I. Preparation for broadcasting
1.Varieties selectionI don't know. Premature, disease-resistant, high-yielding and high-quality varieties are selected, and the main species in the city of bola - no. 54, no. 76, no. 8031, no. 1402; the model - • arable fields: 2186; new cotton 1; gold mine 1565; uusimaa 80; uusimaa 74; uusimaa 75; tsumitsu 509; zuantou 6; uusimaa 52; the main type of seeding in qui river county — uusimaa 54; uusimaa 63; uusimaa 76; uusimaa 1402; model varieties — uusimaa 80; uusimaa 78; uusimaa 67; uusimaa — 508; middle cotton institute 113; k 2725; nh 12026; uusimaa 75. Seeds are required to be 95 per cent pure, 99 per cent pure, 85 per cent budding and < 12 per cent water。
2. All ahead. In the spring, when the surface of the crop is frozen, it is prepared in a timely manner to remain on the air, so that the whole area is “horizontal, loose, broken, clean and clean”. And every time you do that, you pick up the pieces and the pieces。
3. Fabrication. In combination with the fall, all-cultivated areas apply base fat. Acres are subject to decomposed organic fertilizers of 1-2t or oil sludge of 100-150kg, ammonium phosphate of 15-20kg, urea of 8-10kg, potassium sulphate of 3-5kg, zinc sulphate of 1-1. 5kg。
4. Chemical weeding. Chemical weeding must be combined with dredges, with 33 per cent of the acetal lactation 150-180 ml and 3-5 cm deep。
Seed preparation. In order to promote cotton haemorrhoiding, increase the rate of gerontization, two to three days of tan before seeding; carefully select the seeds after sunburning, leaving them full, robust and of the same size; and unpacked seeds are planted in fufu or fragrance. Mifu used 0. 3 per cent of the amount of seed (300g for 100kg seed, 1. 5kg for water, mixed with a water solution); fukudo coats were first cleaned of acids during seed processing (<0. 15 per cent of the acid) and then dryed, fukuoka used 2 per cent of the amount of seed (100kg seed 2000g), and the water mixed with the seed was even with dry bags。
Ii. Sowning
1. Sowing period. Five centimetres of temperature steady enough to sow at 12°c. On 5-20 april and 10-25 april in the city of bola, the general district finished the airing of seedlings in the cotton areas under normal weather conditions for 2-4 days。
2. Sowing methods. 1st membrane line range: 13 cm + 63 cm + 13 cm + 63 cm
+13cm+63cm; average line distance 38cm and range 8. 3-10cm. Four-line line-range configuration of the monolithic: 63 cm+13 cm+63 cm+76 cm with an average range of 38 cm and a range of 8. 3-9 cm。
Three-line line length configuration of the membrane: 76 cm+76 cm+76 cm with an average range of 38 cm and a range of 6. 75-9 cm。
3. Drill belt configuration. Use maze or internal drip irrigation. The drip cord is in the middle of the narrow line of the membrane, with two drip bands in the membrane. The clay uses drip belts ranging from 300 to 350 mm from the drop head to 1. 8 to 2. 2 l per hour from the drip stream; the border soil uses drip belts ranging from 300 mm from the drop head to 2. 2. 6 l per hour from the drip stream; and the sand soil uses drip belts ranging from 250 mm from the drip stream to 2. 6 to 3. 0 l per hour. The location of the drip strip is required to be accurate and moderate, the stream should be lifted up when the maze is laid, and the internal drip strip should be paved with a drip hole。
Seeding. A precision seeding method of 1 grain per cave. Line 3 of the membrane: acre seeding 0. 9-1. 2kg; line 4 of the membrane seeding 1. 2-1. 5kg; line 6 of the membrane seeding 1. 8-2. 2kg。
5. Quality of seeding. A deep 2. 5-3. 0 cm to ensure that seeds reach more than 1 cm. The land is 5-6 cm wide and is heavily suppressed, with a density of 0. 5-1. 0 cm and an empty hole rate of 3 per cent, with an error rate of 5 per cent and a light belt of 5 cm on the side. Direct, accurate, balanced, deep and consistent, to the side。
In order to achieve early growth, the following needs to be done:
1. Slendered soil. After the cotton is soaked, the sheeting must be broken in time and the sapling must be supported by soil production and by seedlings. If the cotton fields are soaked with unsealed soil, it must be sealed in time for the early birth of the cotton。
2. Strengthening farming. According to weather forecasts, when cold rains return, it is necessary to plough in a timely manner, and when it is cultivated, it is necessary to install shreds of earth, which cannot afford large earth blocks, with no “walls”, no seedlings, no saplings, no ditches, and to level off between rows. When dripping cotton fields, they are protected by a bridge or a dirt bag at the service. To promote cotton seedlings by raising the temperature through chinese farming, it is recommended to plant once after each precipitation。
3. Regulation. Accelerant cotton is grown in cotton by 4-5 leafs for the first time, acreage is mechanized with 1 g acetamine to water with 30 kg accelerator, with a strong root and accelerants for the first time, and a second incendiary control is based on the strength of the cotton, with an increase in the use of accelerant acreage of 0. 5-1g as appropriate。
I'm sorry.Pest controlI don't know. Strengthening of insect investigations, application of seal belts around cotton fields, based on the prediction of insects, accurate and timely opening of frequency-interflicted headlights to trap winter-generation cotton bellworms into insects, timely extraction of leaf mites, cotton acupuncture central strains, and tablet selections。
