I. Varieties selection. High-yield, integrated and resistant varieties of oil and vegetable varieties, such as oil research 2020, oil oil 20 and oil research 50。
Ii. Finely grounded and seeded. To the extent possible, seedbeds should have been made of plots that had not been grown in the previous year, either oil or cross-flower vegetables, high terrain, flat soil level, soil dysentery, medium fertility, good water conditions, no shade around them, no swollen disease and the source of the disease。
Iii. Deplantation. 1 - the ploughing plant is moved to the field, which is then ploughed down, tilling the field to the ground level, opening the trunks of the ditches, the gutters, the gutters, the ravines, the ravines, and the gutters, ensuring that the troughs are open and can drain and dry. Per acre decomposed farmers are fat for 1,500 kg, urea for 15-20 kg, calcium for 30-40 kg, potassium for 8-10 kg, and pelicans for 0. 5-1 kg, which are applied evenly when fattening up to the whole of daejeon: 35-40 days old, oil grafts for a “five-leaf one-heart” period are transferred to the whole field, with a planting density of around 6,000 (40 cm and 28 cm). 2. No-cultivation: before planting, the removal of excess weeds or returning to the paddy, and the removal of obscurants such as too long slurry from the soil, can increase the density of the plant, as appropriate, to approximately 6,000-7,000 acres (at a distance of 40 cm and a distance of 24 cm-28 cm)。
Iv. Following fat. In the case of fertilizers, oil-supplied oil-supplied on a long-term basis, using 5-8 kg of urea for acreage; in the case of fertilizers in due course to increase the number of branches and buds, the application of fertilizers can be accompanied by an appropriate increase in potassium fattening and 4-6 kg of acres to promote the growth of oil-supplied vegetables and increase their resistance and resistance to disease. In the case of lack of boron soil, the field in which the bottom fertilizer is not applied shall be sprayed one or two times during the bud, so as to prevent the impurity of oil and vegetables。
1. Agriculture. Prevention and control of oil and vegetable diseases and pests through a combination of green and general control strategies; timely removal of agricultural crop diseases, weeds and agricultural waste, bringing out of the fields for centralized treatment and reducing the number of disease (worm) sources; timely drainage of trenches, reduction of field moisture and reduction of disease incidence. 2. Immunization induction. In the third leaf of oilseeds, choose red. Sprays such as acetate, acetate, carbino-vellose, and a few dbc are used to increase resilience。
(vi) harvesting in due time. Some 30 days after the end of the oil season, 70-80 per cent of the all-field herbs are yellow and green to light yellow, and the main course of the central ace seeds take place when they are inherently colored, and the harvest is dried up 5-7 days later. Where conditions exist, the harvest can be completed in one-time with a joint harvester, while the oil straws are crushed to pieces。
