"Covering" species of onion benefits
Winter cucumber cultivation in winter is usually planted after mid-October, and gradually pulled in mid-June in the following year. Idle time after pulling is as long as 3 months. Welsh onion at the end of March a small arch shed nursery, seedling age of 65 days or so, after the planting of cucumber in the greenhouse after the planting, harvest in October, use this "vacant" time for a turn of green onions, can kill at one stroke.
1. To increase income, select plants with compact plants, thick leaves, solid stems, long stems and white stems, and strong heat and disease resistance. The output per mu can reach about 2,500 kg.
2. Reduce the damage of root-knot nematodes Weeping onion has significant inhibitory effect on root-knot nematodes. Planting green onions can effectively reduce the density and quantity of root-knot nematodes, and reduce the harm to the crops.
3. Effectively reduce the hazards of continuous cropping obstacles Continuous cropping of the same crops in the same plot can easily lead to continuous cropping failures in greenhouses, especially soil-borne diseases. Changes in microbial flora can be caused due to the inhibition and killing of rustling root exudates on soil bacteria. And quantity, to reduce the harm to the next crop.
Planting points:
1. Rational application of fertilizer per acre cooked poultry, livestock manure about 3 cubic meters, potassium sulfate compound fertilizer 30 kg, 20 kg of diammonium phosphate, borax 1.5 to 2.5 kg.
2. Broad line dense planting uses 6 to 7 leaves, 40 cm high seedlings. North and south to open ditch, ditch 15 to 20 cm, spacing 8 cm, spacing 3 cm, planting 2 ~ 25,000 per acre around. When planting, 70% thiophanate-methyl mycoside can be used to irrigate the roots, and when the onions are inserted, they should stand upright.
3. Top dressing, watering, planting, watering, watering, white water, initial growth, watering 2 or 3 times. Scallions are prosperous for a long time, pouring water every 4 to 5 days, and stopping watering 10 days before harvest. In the early stage of light blue-green growth, combined with watering, each application of 15 kg of urea per acre. Onion Baiwang combined long-term cultivation of soil and watering, top-dressing 50 kg of potassium sulfate compound fertilizer three times, and spraying 0.5 times of borax solution once every 10 days.
4. Timely soil combined with fertilization after watering, usually in light blue long-term cultivation of soil 4 to 6 times, each about 3 to 5 cm soil, the soil buried in the leaf sheath, do not bury the leaves, and to avoid harm to the root system.
5. Pest control Weeping onion disease is mainly downy mildew and purple spot, sprayed with 75% chlorothalonil wettable powder 600 times, once every 10 days, even sprayed 3 times.
Can use 2.0% of avermectin EC 7000-9000 times to control green onion and flies, pay attention to spray when adding penetrant, or add 1000 times detergent to increase adhesion and improve efficacy.
Cucumber
Netherlands cucumber for female is more, mainly for greenhouse cultivation, unlike most outdoor cultivated varieties, they can not through pollination fertilization can finish the development of the fruit, but does not form a fully developed seeds.Early female system has the advantage of fruit maturity, high yield.The characteristics of this type of melon is: melon, one section one melon, section 1, 2 and more than 1 section melon melon.And, if appropriate management level, high yield potential is very big, 667 square meters of single crop yield can be over 10000 kg.1 year can be 2-3 times.
