Non-pollution soybean cultivation technology

First, sowing 1. Sowing period: spring sowing suitable temperature, ground temperature stability is greater than 12 °C, usually in mid-March to late April. Autumn broadcast should be in late July to late August. 2. Seed treatment: Wet seeds such as 58% ledomil or metalaxyl Mn zinc are seeded at 0.4% of the seed weight. 3. Seeding capacity: sowing rate per acre 5kg-6kg. Second, field management 1. Miaomiao: After the two true leaves to the first complex leaves unfolded before the first, according to the required spacing or spacing from the seedlings artificial artificial seedlings, pull out weak seedlings, seedlings, seedlings after a one-time Dingmiao . Control planting density and row spacing. 2. Dressing: Seedling stage (one week after emergence), Mushi urea 5-10kg or 5% human fecal urine, the initial flowering period according to the situation, soil fertility appropriate application of compound fertilizer (10-20) kg, the initial period of scab Appropriate amount of foliar fertilizer spray such as spray Po or potassium dihydrogen phosphate. 3. Cultivated soil: After the seedlings are planted and weeded before flowering, we combine the soil with weeds during weeding and weeding. The cultivating period is 10-15 days. Cultivated weeding should avoid plant damage. 4. Irrigation: Soybean is a crop that needs more water, especially flowering to drum grain stage. If it encounters drought, it should be timely watered, and irrigation should be based on the principle of Run-Tian. It should be rainy days in spring and it should be drained in time after rain. In the trench, it is not suitable for long-term accumulation of water. 5. Pest Control a) Prevention of "Rotten Root Disease": Bean sprouts should always inspect the field after they have three true leaves. Timely removal of the diseased plants, and bring out of the field burned, can use high-efficiency, low-residue fungicides such as 58% radamire or metalaxyl manganese zinc 600 times or 72% Precike water 800 times spray plant base, separated 7-10 days spray 1, even spray 2-3 times, in case of more rainfall on the weather to spray more than 1-2 times. b) Prevention and control of anthrax: In the period from the beginning of the flood season to the grain phase, spraying once every 7 days, spraying 2 to 3 times, using 25% of the medicine to make 100 grams of 1000 times, or 80% of Dasheng 800 times. c) Control Spodoptera litura, Spodoptera exigua, and bean pod entice method: Black light traps can be used to trap adult insects or be seduce with sweet and sour liquid (375 grams of brown sugar, 500 grams of vinegar, 125 grams of white wine, 250 grams of water, 90% of trichlorfon 1g), the lure is mixed evenly, and the pot is placed in a place where the bean field is about 1 meter high and the stand is erected. A pot is set at an interval of 20 meters. A new preparation liquid is added in 5 days and the cover is opened in the evening. cover. Chemical control: The drug control is controlled before the larvae are inoculated before the third instar, and low-toxicity and low-residue high-efficiency pesticides are used, such as Kung Fu 4000 times solution, Tianba 800 times solution, Divide 1500 times solution, Ke Mobao 1500 times solution, optionally one Sprays and pesticides shall be alternately rotated, and pesticides prohibited by law shall not be used. d) Control the blackfly of the bean stem: It is more harmful in the 3-6 leaf stage. When it is first seen, it is sprayed with 40% green rapeseed emulsifiable concentrate 1000 times liquid or 1.8% afording emulsifiable concentrate 3000 times liquid, 7 days Prevention once, continuous 2-3 times. e) Control of whitefly and aphids: Use 10% of Dagong Chen or 10% of net wettable powder to spray 15 grams per mu. Third, the harvest and inspection 1. Stop spraying before 15 days before harvest to reduce pesticide residues. 2. The finished product of green soybean is dominated by barley, which should be collected according to the product standard (contract) in a timely manner before the soybean meal turns from green to yellow. One or two days before harvesting, a rapid inspection method for pesticide residue should be used for sampling inspection. After inspection, it can be collected.

Greenhouse Automatic Proportional Pump

Fertilizer pump mounted directly on the pipe, the kinetic energy of pipe flow to drives the pump to work at a set ratio to suck high erconcentration drug or quantitative fertilizer in to the pump. After mixed with the water and delivered to downstream. No matter How to change the water pressure, Drug or fertilizer will be mixed and discharged according to a certain proportion.
