The Management Points of Increasing Phosphorus Fertilizer in Spring Peanut

The amount of basal fertilizer should account for 80% to 90% of the total amount of fertilizer. Some peanut farms only use basal fertilizer, and they can also obtain high yields without topdressing at a later stage. Basal fertilizer can be used for high quality fertilizer from 1,000 to 3,000 kilograms per acre.

Peanut requires more phosphorus than normal crops and has high absorption and utilization of phosphate fertilizers. Tests have shown that applying 10 kg of calcium phosphate per acre results in significant yield increase, and the aftereffect is obvious. When fertilizing phosphate fertilizers in a weak manner, adding 2.5 to 5 kg of urea per acre as a seed fertilizer can better exert the effect of increasing phosphorus production. However, fertilizers and seeds must be isolated when applying seed fertilizers so as not to harm the seeds and affect their germination and emergence.

Peanut applies 10 kg of calcium sulfate per acre, which can not only regulate the pH value of the soil, increase the nitrogen fixation capacity of the rhizobia, but also improve the nitrogen nutrition, promote the development of the pods, and reduce the empty fruit and rotten fruit.

Artificial inoculation of peanut rhizobia can make peanut early nodule, multiple nodules, and improve the nitrogen fixation ability of peanut plants. At present, the peanut rhizobia agent (rhizobium fertilizer) promoted in production generally uses 25 grams per acre. When using it, add appropriate amount of water into a paste and mix the seeds, and pay attention to mix with the seed and prevent sun exposure. Also avoid mixing or contacting with bactericides.

Greenhouse Drip Irrigation System

Fertigation is using your irrigator to fertilise the plants and soils as you water, which is the most efficient and advanced practice of fertilization. Aid of pressure system (or natural divide terrain), the soluble solid or liquid fertilizer, according to the soil nutrient content and crop fertilizer regularity and characteristics of species, with the fat of with irrigation water, through a controlled water supply pipeline system, supplying, the compatibility, water through the pipe and drop head form drip irrigation, uniform, regular, quantitative, infiltration area crop root growth and development, make the main root soil always stay loose and appropriate moisture content, at the same time according to different crop fertilizer characteristics, environment and soil nutrient content in soil; Crops in different growth phase water requirement, the different development stages of the fertilizer rule is the demand of design, the water and nutrient timing quantitative, provided directly in proportion to the crops.
