With the delay of rice maturity, the development of rapeseed direct seeding in recent years has been greatly affected. In order to expand the live rapeseed cornucopia and stabilize the rapeseed production, Jiangcheng has conducted experiments and demonstrations of autumn broccoli and field rapeseed in the past two years and achieved good results. In 2010, in the autumn broccoli field, we planted Ningza No.21 rapeseed. In early June of the following year, rapeseed was harvested in 165-220 kilograms per mu, with an average yield of 194 kilograms per mu, which was higher than the average annual output of 189 kilograms per year in Jiangdu City. . Ningza 21 is cold-resistance, lodging-resistance, disease-resistance, and strong anti-cleft-angle, suitable for live broadcast and mechanized rapeseed harvesting. The following points should be noted in the podcasting of autumn broccoli.
Appropriate cropping in appropriate period The broccoli field that was harvested from late October was selected and the symbiosis period with rape was controlled at about 20 days. The suitable sowing date for Jiangdu rapeseed is in early October and no later than October 20. Use 0.25-0.3 kg per acre to ensure that the basic seedlings per acre are between 20,000 and 40,000, and the actual harvest density per mu is about 25,000. Use a 50 mg/L solution of uniconazole for seed dressing, air dry and sow. Before sowing, a horse race was planted on a dry land and speed irrigation was conducted. The next day was broadcast. Attention should be paid to picking broccoli while clearing the sorghum. When the sorghum is clear, it is necessary to timely replenish and replenish the seedlings to ensure that the seedlings will pass winter.
Scientific Fertilizer Fertilizer The field of broccoli field is fertile, and cultivar rapeseed requires less fertilizer than paddy field cultivars. The principle of fertilization is to apply basal fertilizer, supplement seedling fertilizer, reapply fertilizer, skillfully apply fertilizer, and apply boron fertilizer during flowering. In the general growth period, 18 kg of pure nitrogen, 4 kg of phosphorus pentoxide, and 6 kg of potassium oxide are required per acre. The proportion of base fertilizer and alfalfa fertilizer on nitrogen fertilizers is 6:4. Basal fertilizer before sowing with 45% of compound fertilizer 25 kg, borax 0.5 kg, applied to the broccoli between the lines (part of the compound fertilizer seed dressing); Miao Fei rape seedlings in the 3-leaf period of 5 kg of urea per acre; After returning green, the initial stage of convulsions (late February to early March) applies fertilizer, 10 to 15 kg of urea per mu, and 5 kg of potassium chloride; depending on the condition of the seedlings, flower fertilization usually applies 3 to 5 kg of urea per mu; Control Sclerotinia and spray the instant soluble boron fertilizer to increase the seed setting rate and 1000-grain weight.
In addition to chemical and pest control broccoli fields generally intensive cultivation, weeds base less, in addition to generally after the harvest of broccoli weeds out. Monocotyledonous weeds were controlled with quizalofop-pray spray, dicotyledonous weeds were used for herbicide control, and dicotyledonous weeds were mixed with the two drugs. With spray control. The broccoli field is fertile and the planted rapeseed grows vigorously in the early stage. It is particularly important to control the antifreeze. Generally at the end of November and early December, when rape is in the 5-6 leaf stage, 15% paclobutrazol WP can be sprayed with 30-50 grams of water per acre to promote dwarfing of the seedlings, enhance cold resistance, and ensure safe wintering. In the symbiotic period of rape and broccoli, the low-toxicity and low-residue pesticides should be used in the control of the yellow-striped flea beetle and cabbage caterpillar.
Mechanized harvesting of Ningza 21 has good anti-cracking properties and is suitable for mechanical harvesting. Generally, the harvest is delayed 4 to 5 days after the artificial harvesting, and when the green kernels are below 5%, it is harvested to ensure that the loss rate is similar to manual harvesting.

Due to people's attention to their own health, Plant Extract medicines have natural sources and less side effects compared to chemical medicines, and plant extract medicines have also attracted attention.
Pharmaceutical grade plant extracts are for the purpose of curing diseases. The same plant extract product can be divided into medical grade and Health Care Grade according to different purposes. Pharmaceutical grade plant extracts contain a single active ingredient and have a high content of active ingredients. Health-care grade plant extracts require low active ingredient content and play a preventive and protective role. In the future pharmaceutical products, medicines derived from natural plant extracts will occupy a very important position.
