Rapeseed is one of the main oil crops in China. The cultivation method is divided into seedling transplanting and no-tillage direct seeding. At present, most of the planting regions mainly adopt seedling transplanting methods. Its main measures are as follows;
1, fat enough to fill up, strong seedling transplanting, reasonable close planting. No matter if it is nursery seedlings or field seedlings, it must be sufficient to get enough food and the soil is free of pests and diseases. To plant according to the time of agriculture, and to spray a new high-fat membrane to protect the effectiveness of fertilizer protection, prevent pests and diseases, and promote strong seedlings. When transplanting, select erected seedlings with well-developed roots and healthy plants to plant them in a reasonable and dense plant. After transplanting, a new high-fat film should be sprayed to protect the leaf surface, protect the bottom of the plant, prevent pests and diseases, effectively promote the healing and rapid growth of root wounds, and effectively prevent winters.
2, weeding living soil, fat and protect, strong body strong moss. After returning to spring, it is necessary to carry out cultivator and weed control, prevent soil compaction, protect soil, eliminate water and fertilizer competition, and spray new high-fat membranes to enhance the above-mentioned functional effects. In the bud stage, spraying strong seedlings to strengthen the physiological function of crops, in order to enhance the unobstructed transport of the body's nutrient, strong seedlings, promote the absorption of nitrogen, phosphorus, potassium and trace element supplementation, conducive to the formation of Leiye, improve rapeseed by powder, The quality of fertilization increases the weight of grains, promotes the rapid and robust growth of fruits, and lays the foundation for a good harvest.
3, prevention and control of pests, materialization and use, focusing on results. Rapeseed has suffered many disasters throughout its life, and the pests and diseases are complicated. In the seedling stage, the prevention and control of pests and downy mildew such as cabbage caterpillar, aphid, earthworm, earthworm, etc. should be strengthened. The flowering period is mainly to prevent sclerotinia and prevent leggy, and in the infestation stage, it mainly strengthens the control of aphids and white rust. For the prevention and control of these pests and diseases, in addition to the use of highly targeted agents, new high-fat membranes should also be added, and the control effect should be doubled.
