Peanuts are inconvenient for topdressing due to mulching cultivation and underground results. Most of them are fertilized one time before sowing, resulting in prolonged lodging in the early stage, early defermentation and premature aging, increased leaf spot disease, early leaves, poor pod filling, and affecting yield and quality. Fertilizer effect post-shifting technology refers to the use of slow-release fertilizers, organic fertilizers, organic-inorganic compound fertilizers, bio-organic fertilizers and other slow-release long-acting fertilizers, delaying the fertilizer efficiency period, enhancing the fertilizer efficiency in the middle and late stages, and controlling the prolonged period to prevent premature defamation and premature aging. Improve fertilizer utilization and reduce pollution of the environment to the environment.
Increase production and increase efficiency: generally increase production by more than 10%, and increase the rate of profit by 2 percentage points.
Technical points 1. The spring-sown peanuts are covered with plastic film, and the high-yield grain fields are subjected to two-time production such as summer live film or wheat field interplanting. The rotation is changed, the deep cultivation in autumn and winter is deep, and the organic fertilizer is added to fertilize the soil.
2. Coated controlled release fertilizer was used. The sulfur-coated or resin-coated urea with controlled release period of 3 months is applied in a ratio of 1:1 with ordinary urea, and then combined with phosphorus and potassium fertilizer. High-fertilizer land needs to exert fertilizer effect later, and the proportion of controlled-release fertilizer can be appropriately increased. The dry land needs to exert fertilizer efficiency earlier, and the proportion of controlled-release fertilizer can be reduced. The general fertilization quantity is: high fertility plot of about 500 kg per mu, 4000-5000 kg of organic fertilizer, 12 kg of phosphorus pentoxide, 12 kg of pure nitrogen, 10 kg of potassium oxide; medium fertility of 350-400 kg per mu. The plot, the application of organic fertilizer 3000 kg, phosphorus pentoxide 6-8 kg, pure nitrogen 8 ~ 10 kg, potassium oxide 4 ~ 5 kg. Or use coated controlled release blending fertilizer 40~50 kg/mu.
The organic fertilizer is applied before the cultivated land, and the fertilizer is concentrated in the ridge once in the ridge.
3. Suitable for late broadcast. Spring sowing peanuts were postponed until the end of April to mid-May, and the wheat peanuts were planted in late May, and the summer live broadcasts were broadcast early in mid-June.
4. Choose high-yield varieties and properly close them. The large peanut variety Fenghua No.1 and Shanhua No.9 are 0.80~0.9 million piers per mu, Fenghua No.5 and Shanhua No.7 are 0.9 million to 10,000 piers. Small peanut varieties Fenghua 4, Shanhua 8 and other 10,000 to 11,000 piers, 2 per pier.
5. Other measures are the same as usual.
Suitable promotion areas: Shandong Province and Huanghuaihai area.
Matters needing attention: Drought affects the coated controlled release fertilizer to exert fertilizer efficiency, and should be combined with irrigation when it needs to exert fertilizer effect in case of drought.
