Facility cucumber less poultry manure
Fertilization principle
Facility cucumber advocates the application of high-quality organic compost, the old vegetable shed should pay more for composting with more straw, less fertilized manure, and the application of organic and inorganic fertilizers and straw returning. According to the soil fertility conditions and the application amount of organic fertilizer, comprehensive consideration of environmental nutrient supply, appropriate adjustment of nitrogen, phosphorus, potassium fertilizer application.
After planting, the seedling stage should not be frequently topdressed, nitrogen fertilizer and potassium fertilizer should be applied in stages, a small number of times, avoiding the application of compound fertilizer with high phosphorus content, high-nitrogen compound fertilizer in the early stage, and potassium fertilizer in the middle and late period.
When the acidification of vegetables is serious, an acidic soil conditioner such as lime should be applied in an appropriate amount.
Advocate the application of water and fertilizer integration technology to achieve water control and fertilizer control, improve quality and increase production costs.
Fertilization advice
The seedling fertilizer is added to the decomposed organic fertilizer, and the phosphate fertilizer is applied. 60-100 kg of decomposed organic fertilizer is applied per 10 m2 seedbed, 0.5-1 kg of calcium magnesium phosphate fertilizer, 0.5 kg of potassium sulfate, and 0.05%-0.1% urea is sprayed according to the seedling condition. The solution was 1-2 times.
The base fertilizer is applied with 4 to 5 square meters of high quality organic fertilizer.
The production level is 3000-6000 kg (per mu, the same below): nitrogen fertilizer 12-20 kg (pure, the same below), phosphate fertilizer 5-9 kg, potassium fertilizer 15-24 kg. The production level is 6000-9000 kg: 20-28 kg of nitrogen fertilizer, 9-15 kg of phosphate fertilizer, 24-36 kg of potassium fertilizer; the yield level is 9000-12000 kg: 28-36 kg of nitrogen fertilizer, 15-18 kg of phosphate fertilizer, 36-48 kg of potassium fertilizer; The production level is 12,000-15000 kg: nitrogen fertilizer 36~45 kg, phosphate fertilizer 18~24 kg, potassium fertilizer 48-60 kg.
All organic fertilizers and phosphate fertilizers were used as base fertilizers. The initial flowering period was mainly controlled. The nitrogen and potassium fertilizers of autumn and winter glutinous rice and winter spring glutinous rice were divided into 7 to 9 times of topdressing, and the nitrogen and potassium fertilizers of wintering glutinous rice were divided into 10 to 14 times. High potassium compound fertilizer or water soluble fertilizer. The amount of nitrogen fertilizer applied per time does not exceed 4 kg.
Appropriately increase planting density, build a reasonable population, and increase fertilization effects.
