“in addition to having an economic income, the cultivation of vasectomy can develop tourist agriculture. In the process of planting, the key is to “triple the level” of good breeding, planting and gardening.” in recent days, yuan dang, a farmer at the south gang county agricultural department, has travelled to the village of ishiba, yuanzhou, to teach farmers about planting techniques。
Infants
1 time, area, number of seeds. The birth time depends on the time of planting. It usually takes 20-25 square metres for each acre to grow a seedling bed about 40 days before the planting takes place, with about 30 kilograms。
2 the method of breeding. It can be grown both in open ground and in small arch sheds, usually with small arch sheds. The seedbed shall choose the backwind to the sun, and the east and west to the better. The width, length and management convenience of the seedbeds are appropriate and generally should not exceed 1. 3 m. The archer is about 60 centimetres high。
3 whole fertilization. In general, deep, lax and well-ventilated soil should be selected for chrystal. The topsoil ploughs 20-25 cm, which makes the surface soil soft and thin and flat. Each acre bed is fertilized with 200 kilograms of soil, 2 kilograms of manure for the sole purpose of the chrysanthemum, which is rolled into the ground, where the fertilizer is spread evenly, where it is drawn into the ground and then the soil is fined and levelled。
4 seed treatment. Seeds are selected first, impurities and seed are removed and seeds are fully filled. The selected seeds are tanned in order to kill the fungus and increase the growth rate. Seeds are immersed in hot water at 35°c-40°c for three to four days before seeding, then they are rinsed with fresh water and can sow when the water is dry. In order to prevent the disease during the shrunk season, the drug can be ploughed with methyl tobuzin or enzymes。
Five seed. The seeding should be free of wind and clear. On the day of seeding, the seedbeds are filled with water, which can be sowed once the water has dipped. The seed is sowed with well-treated seeds mixed into the fine sand and distributed in two or three waves over the seedbed. The seeding is followed by a plume of 0. 7-1 cm。
Six seedbed management. The chrysanthemum comes out six to seven days after seeding, so that the temperature in the nursery does not exceed 30°c, so as not to cause the burning of seedlings and rotting roots. When the sapling is up to about 3 cm and the first pair of real leaves spread, attention should be paid to ventilating and preventing the wavelength. The temperature in the seedbed is maintained at 25°c-27°c and should be ventilated at 8-9 a. M., without ventilation at high noon temperatures, in order to avoid the creation of flash seedlings. If the weather cools, the ventilation stops. When the average outdoor temperature is stable at more than 12°c, clear and windless weather should be chosen, the film removed and weeds removed from the nursery. In the event of a shortage of water, water should be sprayed over and filmed and vents increased, and water should not be overloaded in the seedbed in order to preserve the wetness of the dry beds between the beds. The outdoor temperature should be stabilized at 15°c and the membrane seedlings should stop watering about seven days before the planting to prepare for it。
Migration
1 land block selection. Land that is free of internal flooding, easy to drain, light and high organic content is preferred for chrysanthemum cultivation。
2 planting time. The plant was usually moved around 20 may. At the time of planting, it was required to be 0. 3 centimetres thick, 15-20 centimetres tall and 3-4 pairs of real leaves。
3 plantation technology. Cultivation is generally carried out in broad and narrow lines of 70 cm, 50 cm, 25 cm and approximately 4,500 basic seedlings per acre, which are grown by small branches. After planting, water is pouring in, causing early seedlings and early rooting。
Management
After planting, a small number of branches are found when the seedling is 25-30 cm high, and the soil can be taken from the gutter for planting on the base, in order to promote uncertainty of root, prevent invertation and inhibit the growth of the grass under the membrane。
2 integrative trim. The manshin is growing in the summer and is expected to be cut in time to control heights. It's short, it's early and it's easy to control. Due to the length of the flowers, their late growth, and the age of the leaves, the shrouded leaves and flowers shall be sown in time. High- and medium-duper varieties need to stand up and pull double wire to support the stem in case the wind blows。
3 fertilizer water management. It is grown on a sun-rich, loose and fertile soil and does not require extra fertilization after planting. In the case of poor soil, 2-3 urea 0. 3% urea sprayed on the folate in the growing seasons of pregnancy buds and flowering seasons and 0. 5% potassium phosphate added. Because it is more drought-resistant, water is generally not watered, except during particularly dry summers。
4 pest control. The pests and pests of the chrysanthemum are mainly viral diseases, deadness and red spiders. The virus is treated with viral and bacterial poisons; 75 per cent of the disease is treated with bacillus, polybacterium, aluminum and methyl tobuzin; and the red spider is treated with 50 per cent of the milk of malathion at an initial rate of 1,000 times the milk, one in seven days and two in a row. Underground pests are mainly larvae, with a 3% furfuran per acre or 5% phosphorus per grain 0. 75-1 kg combined to be transported into the soil. Red spiders, aphids can be treated with 1. 8% mites and cracks. Precautionary and preventive principles must be upheld in cases of degenerative diseases, plagiarism and root causes. Usually a microbicide is used once during the flowering period。
