1. Timely tillage, weeding and early top dressing
Weeding and weed control can prevent the reduction of soil compaction and soil conservation, eliminate the competition between fertilizers and water between field weeds and rapeseed, and at the same time destroy the antagonism between soil microorganisms and rapeseed rhizosphere microbes. General Honda Cultivated grass 3-4 times. In line with the principle of "light-deep-light" and unblemished before the rain, it should be done early and diligently. Regular inspections should be made to remove the pennisetum. Topdressing should be done early to promote early-onset, rape seedlings need less growth, seedlings need fertilizer after the bud stage, and the fertilizer effect release is relatively slow and lasting, the re-application of the base fertilizer and early application of fertilizer can just meet the rape Reproductive growth phase of the fertilizer needs; at the same time, the need to combine spraying Spruce Cape 6000 times, supplement six trace elements, promote the absorption of nitrogen, phosphorus, potassium, conducive to the formation of buds. In the fall of 5-8 true leaves during the period of cultivation and weeding, 12.5 kg of potassium fertilizer, 5 kg of phosphate fertilizer and 7.5 kg of urea were applied in the rhizosphere to promote autumn hair. Before the beginning of spring, before the opening of Brassica napus, that is, the opening of the rape line, and then mu 12.5 kg of potassium fertilizer, 5 kg of phosphate fertilizer, urea, 7.5 kg of rhizosphere top dressing to promote spring hair. After the fertilization, the base soil around the root can be timely and concentrated, and the effect of the fertilizer can be concentrated for a long time, and at the same time, the lodging can be prevented at the same time. If rape can be guaranteed in autumn and spring, it will be able to obtain high yield in the later period.
2. Pest control and chemical control
Seedling stage should mainly strengthen the prevention and control of cabbage caterpillars, aphids, tigers, earthworms and other pests. Can be used 1000-1200 times effective treatment. The other major disease during the seedling stage is downy mildew, which can effectively prevent downy mildew by spraying gully or spraying water at a rate of 1500 times in soft water, plus 1000 times of Nail or 1200 times of Mahe every 7 days, and spray 750 times. Mahe is effective in treating downy mildew. Mahe is a new and unique formula suspension agent launched by Singapore Linon, which has a good effect in preventing and controlling diseases and downy mildew. The flowering period is mainly to prevent Sclerotinia and prevent leggy. In the first week after the initial flowering period, the use of soft water 1500 times per mu + stercopic 6,000 times or Philip van 1000 times + pigeons effectively prevent Sclerotinia. In the Qing Lan period, the prevention and control of aphids and white rust are mainly strengthened. Locust control should be sprayed with a high-pressure sprayer over 1000-800 times over a large area. Prevention of rust can be 1200 times every 7-10 days nano xin.
3, timely harvest
When the kernels in the main stem of the plant begin to turn yellow and brown, they can be harvested. The harvest should be sunny morning to avoid the loss of pods. When harvesting fruit sticks should be cut longer, then the sun will be bundled to promote post-harvest. Fine play fine, particles return to storage.
