Broccoli Fertilizing and Planting Management Techniques in Autumn and Winter
Broccoli has a good taste and high nutritional value and is favored by consumers both at home and abroad. Whether it is export earnings or the winter season to enrich the people's table, broccoli is a good main vegetable. In addition, the cultivation of broccoli is simple and the production efficiency is good. It is deeply loved by farmers. In this article, the microbiological fertilizer expert Gembab summarized the cultivation characteristics of broccoli as follows: 1. Planting broccoli planting water and fertilizer management Broccoli is a kind of fertilizer-resistant vegetable. During the growth and development, it needs to supply enough nitrogen, phosphorus, and potassium nutrition. Nitrogen fertilizer is the most important factor affecting the yield of broccoli. Before the planting, we must deepen the soil, combine 1500 kg of cow manure per mu, and 30 kg of compound fertilizer, 20 kg of calcium, magnesium, phosphorus, 2 kg of borax, and 5 kg of magnesium sulfate for site preparation. Unbalanced use of basal fertilizers can cause changes in the soil structure. Therefore, we recommend that vegetable growers use some microbial fermentation fertilizers such as dichotomy microbial fertilizers as basal fertilizers because microbial fertilizers can increase the utilization efficiency of basal fertilizer by promoting the decomposition of various elements, and Secreted auxin promotes seedling growth. According to the north-south direction, the sorghum is ditched. When planting for 15-20 days, 7 kg of urea is applied per acre. When 15 plants are planted, 10 kg of urea is applied per acre. When plants are 20 to 21 leaves, 10 kg of urea are applied per mu. Magnesium and phosphate fertilizers. In addition, boron, magnesium and other trace elements have a certain impact on the growth and development of broccoli, so during the ball-bearing period combined with the top dressing fertilizer 2-3 times potassium dihydrogen phosphate, molybdenum fertilizer, borax and other fertilizers. 2. Disease Prevention and Control of Broccoli Planting in Greenhouse When field inspections are conducted in time, and diseases and insect pests are found, measures must be taken to prevent and treat them in a timely manner. In order to ensure the quality of broccoli, try to take physical control methods. If the comprehensive prevention and control measures for the chemical control methods of powder spraying and spraying are to be adopted, the following principles shall be observed: Priority shall be given to the use of green and non-polluting pesticides for prevention and control. The use of highly toxic and high residual pesticides is strictly prohibited, and the use of pesticides and the number of uses thereof are minimized. Strict implementation of safety intervals for the use of pesticides. The main diseases of broccoli are soft rot, downy mildew, and sclerotia. Soft rot disease can be treated with 72% agricultural streptomycin soluble powder 100 times or 30% copper oxychloride suspension 300 to 400 times liquid. Downy mildew may be treated with 400-600 times of metalaxyl or 64% of Kimradomer Mir WP. Sclerotinia disease can be controlled with 50% speed Keling 1200 times. 3. Greenhouse broccoli pest control Pest control as far as possible using light trapping, yellow trapping, insect nets and other physical control methods. The main pests of insect pests include Plutella xylostella, Pieris rapae, and aphids. Plutella xylostella control methods include black light trapping adult worms or Bacillus thuringiensis preparations directly sprayed or diluted at a concentration of 500-800 times to spray control. The cabbage caterpillar can be directly sprayed with a Bacillus thuringiensis preparation or diluted at a concentration of 500 to 800 times, or 500 to 800 times of the liquid of the insecticide of the bacterium No. 6 of the bacterium, or 1,000 times of the solution of diflubenzuron. The locust control can be sprayed with 5% large heroin 1000 times solution. The principle of spraying is to spray once every 7-10 days and spray 2 or 3 times continuously to produce drug resistance for the prevention and reduction of pests and diseases. The drugs should be used alternately. In order to ensure the quality of cauliflower, all medication should be stopped 10-15 days before harvesting. 4. Greenhouse broccoli cultivation and harvesting When the broccoli flower matures, the bud particles are slightly loose for the best harvest period. If high temperatures are encountered, harvesting should be carried out 1-2 days ahead of time. Harvesting should be carried out along with the flower stems; manual harvesting methods should be used, preferably in the early morning or early evening.
