Guilin rohango's high-yielding technology
- torifan wait
The country's rohango growing areas are mainly located in guangxi, guangdong, hunan and jiangxi, with yongfook county, longsheng county and quiuing district of guilin being the origin centres of rohango and growing for over 300 years. The climate conditions in quillin, the ecological environment are appropriate for the growth and development of rohango, and the variety of resources is extremely rich. In recent years, an efficient business model has been introduced, with rohango growing and expanding rapidly throughout the state, xingan, yang, quiang, quim, with a base area of over 16,666. 7 hm 2, with a gross product of over 100 billion yuan. The rohango industry has become one of the leading sectors in the rural economy of the city of guilin. Rohango is a drug of dual-use chinese medicine, which has the effect of warming the lungs and coughing, and often has a good effect on respiratory infections. The supply of and demand for its unique drug rationality has contributed significantly to the development of the rohango industry. In 2020, the area under rohango was 200 hm 2, with a production of 0. 32 million, with a production value of more than $100 million; the main areas of production were puangjiang commune, phoenix town, grand west town, two rivers town, zhou wan town and county-wide town. To improve the development of the rohango industry, a summary of the high-yield cultivation techniques in rohango, taking into account soil, climatic characteristics and production in the quinoc region, is provided for information purposes。
1 land selection
The selection of the rohango plant takes into account the following three factors: first, adequate light, a backwind with trees, high temperatures and easy water drainage; second, strong and fertile soil of yellow or black gravel, which is not suitable for cultivation; and third, plants such as mountain medicine, watermelon, pumpkin, tomato, tobacco, etc., which are not suitable for fertilizers, which are not suitable for cultivation; and, third, plants such as grasshoppers, pumpkins, tobacco, etc., which avoid planting plants that are exposed to the effects of leaf-based virus disease, resulting in the loss of production or even harvest。
2 base manure preparation
Before planting, 2,000 kg of pig and cow dung, 100 kg of manure, 100 kg of phosphorus fermentation, 100 kg of fermentation, and 3 to 4 kg+ 10 g of boron are used as base weight。
3. Reclamation of land
For an abandoned mountain or or orchards suitable for the planting of rohango, the trees must be cut off from the ground at the summer fall festival, then the whole garden must be dug up at the end of the autumn 30 to 40 cm, the soil must be tanned, fertilized over winter, fertility and pests eliminated. In the second year, the whole garden was replanted once in the first month of planting, and the earth was broken into a dredge, which was 180 cm wide and 30 cm high, with 40 cm wide drains to rise high, after the above operation had been completed, and the pre-sprung herbicide was finally covered。
4 cultivation
4. 1 timing of cultivation
Cultivation in the area of guiang is usually held between 20 march and 30 april, requiring a steady return of temperature to above 15°c, with a better choice of warm and clear day. Late planting leads to long periods of slow growth。
4. 2 cultivation density
The range is 180 cm %ud7 (220 - 250) cm, with 150 - 170 acres。
4. 3 crop varieties
In recent years, the quillin region has chosen to grow such excellent groups of seedlings as the reds, the greens, and the crowns of the guangxi agricultural academy of sciences。
4. 4 methods of cultivation
First dig a 30cm wide, 20 cm deep, and then apply 3 to 4 kg of fully fertilized base fat to the ground in each pit, covering 10 to 15 cm in isolation from the ground, so as not to plant seed and touch the fertilizer with burns。
When planting the rohan seedlings, first the base of the seedlings on the nutrition cup is contained with the left finger and medium finger, then the right hand is put on the left hand, and then the cup is removed; then the seed and the soil are taken into the established den with both hands, with 10 cm and more covered in the soil, and the earth is pressed down and the membrane is covered. The recommended membrane cultivation can increase the temperature of the ground, the rapid growth of seedlings and the prevention of weeds, save labour costs for weeding, while fertilization is not easily lost and increase fertilizer utilization。
After planting, the water is fixed in a timely manner, at the four corners of 10 cm from the seedling, with 4 50 cm or so long bamboo sticks, placed under a two-headed sheet of thin membranes, which is compacted around the bottom. Packages are used to protect against the cold and to protect against pests and seedlings, to effectively promote the early growth and survival of young children。
The general configuration of pollination trees is organized at a ratio of 2 males per 100 plants。
5 bus
By may, the shed had been set up, requiring it to be high around 2 m to facilitate farming operations such as fertilization, spraying and artificial pollination. Choose to use a 2. 4 m long cement stake, press the 2 m%ud73 m stand, bury 40 cm in the soil, with a vertical latte on the top, pick a few iron wires to be buried deep in the soil in thunderproof rain, and then lay a nylon net。
6 shrimp management
When the seed is up to 0. 5 cm, the thin membrane bags are removed, and the side buds are often removed, so as not to affect the growth of the seedling. After planting, around 6d, the 1st leaf can be applied either to the first leaf or to the rare earth, to prevent the emergence of rigid seedlings, 5-8 cm to the seedlings, and every 7 d thereafter, to control the principle of “a small number of times, from thin to thick, from close to far” to prevent the application of fertilizers from being too close to the seedlings base and in high concentrations. Usually, after planting 15 d, the pits start to go after fat。
7 orthopaedic cuts
7. 1 the chicken method
In time to remove the side sprouts and curls before the main chickens are mounted, when the height is 30 cm, a pole is inserted to lead the main chickens to the stand, and when the main chickens grow to 6-8 leaves, the top is taken up by 4-5 knots, the heart is taken out by 2 first-degree chickens; the first-stage chickens grow to 6-8 leaves, the top is taken up by 4-5 knots, each of which is taken to the heart, and the second-stage chickens are taken by 2-3 bars. Let all the three-stage chicken huts grow in one direction. After the sapling, we're going to trim, we're going to cut all the thin branches, we're going to lay the vines, we're going to get to ventilation, light, air。
7. 2 top control
In general, the second- and third-stage chickens are the main result branches and are seeded when they grow to 4-15 leafs; if they do not, a short cut of the third-stage chicken leaves 3 leaves when they grow to 7-8 leaves, allowing them to grow the lower-stage chickens, and a timely roofing process is carried out for 8-10 seed branches per outcome, in order to concentrate nutrients to provide sufficient seed growth and promote early flowering。
7. 3 characteristics of results
From mid-june to mid-august of each year, the most productive period for the flowering of rohango. In general, from mid-june to mid-july, and from late august to mid-september, the two most desirable periods for the rohango outcome were periods when fruit and fruit were thick and internal seeds were particularly strong. In late july and mid-august, high temperatures affected by adverse weather conditions resulted in poor seeds, low sit-in rates and small fruit。
8 fertilizer management
(b) first-time pursuit of fat: 2. 25 kg of manure for each man with decomposition and water-coated manure during planting around 7 d. Second fat chase: 4. 5 kg of human urine per man with decomposition and hydrocortification at 50 cm height. The third fat chase: entering the flower season in mid-july, re-activated flower fattening, 0. 5 kg of manure, 0. 5 kg of manure, 8 kg of manure, 0. 3 kg of compound fat, which is applied in a shallow ditch at a distance of 50 cm from the main dry. The 4th follow-up: during the period of rapid growth and expansion of a large number of fruits in the months of august and september, a further run of fertilizers, 0. 5 kg of manure per decomposition, 0. 5 kg of cylindrium to water, 0. 3 kg of compound fertilizers, and an open shallow ditch at 50 cm from the main dry。
9. Pollination
9. 1 flour harvesting
It's usually appropriate to pick a male at 5:00 to 9:00 a. M. While he's waiting to be released or even opened. Take it and put it in the shade。
9. 2. Pollination methods
The male petals are removed and attached to the home-made bamboo poles, so that the female column is softly covered with a male pole,1 a male can pollute 10 to 20 female flowers, or spray pollination under the guidance of a technician。
9. 3 timing of pollination
In general, 1 d can pollen 500 to 800 plants per person and pollination must be done in the morning, preferably from 7:00 to 11:00 a. M. The incidence of pollination is low in the afternoon. And pollination requires that the sprouts be grafted to the top in a timely manner and that all the thin branches be cut, so that the dispersive light can contribute to high productivity through the sheds, otherwise the fruit will be smaller because of the many vines and the few shades。
10. 1 cyclops
(b) in early may and mid-july, 3. 2 per cent of avilin 500 times its fluid was used for planting pits with thin fat water。
10. 2 cotton bellworms
Sprayed polygonal virus 750 times the fluid for cotton bell bugs in may-august。
10. 3 fruit flies
During the month of august and november, fruit flies were treated with yellow stickers or sweet vinegar。
10. 4 cucumbers, red spiders, aphids, foliage, elephants, elephants
From late april onwards, every 7-15 d time a pest such as cucumbers, red spiders, aphids, foliages, elephant nose worms, walruses was prevented and 90% of trichlorfon 1,000 times the fluid, 3. 2% of avilin 750 times the fluid or 80% of dichlorvos cream 800 times the cream sprayed 3-4 times。
10. 5 frosty, disease
Excretion of frosted urine manganese zinc or alkyl in the months 4 to 5。
10. 6 anthrax
Between may and june, 800 times more was sprayed in amishda to combat anthrax。
10. 7 viruses
The first is to strengthen the management of fatty to grow strong seedlings and to increase the resistance of plants to disease; the second is to spray sugar or hydrochloric acids and treat viral diseases by 1,000 times。
10. 8 bacteria
The application of agro-chainicillin is 1,000 times the liquid for the control of bacterial corneas。
10. 9 decomposition, atrophy, leukemia
Sprayed with aphrodisiac, abdomen and abdomen。
10. 10 decay
In the period between may and july, the use of agro-chain carcininin, ninnammicillin, mesophyllin, 750 times the root of liquid gonorrhea。
10. 11 ashy
The application of fungus protection is 1,000 times less than asphyxia。
11 harvest
When the fruit is actually pollinated, 60 to 70 d, the fruit handle is yellow and can be harvested when fully mature. When harvesting, be careful to take it lightly, cut it with scissors, flatten the wreath and avoid damage. When the fruit is recovered, it is distributed on board and sold and baked in due course。
