What kind of fertilizer should be used to grow peanuts?

Peanut is one of the main cash crops in our country, the planting area in our country is also quite large, rich in fat and protein and other nutrients, the nutritional value of people is extremely high, fertilization in the process of peanut growth is essential, good fertilizer is to improve the yield and quality of peanuts premise, let's take a look at planting peanuts with what fertilizer!

Principles of Peanut Fertilizer Requirements

1, a large number of elements: peanut nitrogen phosphorus and potassium ratio requirements for 3: 0.4: 1, nitrogen is the most, followed by potassium, phosphorus is the least, for this reason in a large number of element fertilizer topdressing should be mainly nitrogen, potassium appropriate.

2, trace elements: peanuts on calcium, sulfur, magnesium and other elements demand the most, calcium can promote peanut plants to accelerate growth, sulfur can improve the protein content of nuts, magnesium can promote the normal formation of peanut chlorophyll.

Principles of Fertilization for Peanut Planting

1. Organic fertilizer is mainly used, inorganic fertilizer is supplemented: organic fertilizer has complete nutrients, can increase soil aggregate structure, improve soil physical and chemical properties, and is beneficial to rhizobia activities, increase nitrogen sources, and use with chemical fertilizer to reduce the loss and fixation of inorganic fertilizer.

2. Apply enough base fertilizer and appropriate topdressing: organic fertilizer is used as base fertilizer. Under the condition of applying enough base fertilizer, it should be timely and appropriate topdressing with quick-acting fertilizer according to the growth situation. At the same time, nitrogen, phosphorus, potassium and trace fertilizer should be reasonably matched, and foliar fertilizer should be sprayed according to the growth in the middle and late stages.

What kind of fertilizer is good for planting peanuts?

1. Base fertilizer: base fertilizer includes base fertilizer and seed fertilizer. The fertilizer applied in combination with cultivated land before sowing is called base fertilizer, and the fertilizer applied intensively in sowing ditch or hole opening is seed fertilizer. Peanut base fertilizer accounts for more than 80% of the total fertilizer, should be mainly organic fertilizer combined with nitrogen, phosphorus and other fertilizers, the specific application method varies with the type and quantity of fertilizer, generally should be scattered and concentrated combined, most of the soil preparation before sowing for base fertilizer, leaving a small part combined with sowing concentrated furrow or hole application. In order to improve the efficiency of phosphate fertilizer, phosphate fertilizer and organic fertilizer can be stacked for 15~20 days before fertilization. The effective rhizobia can be increased by seed dressing with rhizobia agent when peanut is seeded. In addition, trace elements needed by peanut can be supplemented by seed dressing or seed soaking with 0.2~0.3% ammonium molybdate or 0.01~0.1% boric acid aqueous solution.

2, topdressing: according to peanut growth should be timely topdressing, seedling topdressing should be carried out before the beginning of flowering, general topdressing urea 80~100 kg/square kilometer, calcium superphosphate 150~200 kg/square kilometer, trenching strip application. After flowering, gypsum powder 300~400 kg/square kilometer and calcium superphosphate 150~200 kg/square kilometer can be applied to increase phosphorus and calcium nutrition in the fruiting period. Under the condition of defertilization and no topdressing in the pod bearing stage of peanut, 0.2% potassium dihydrogen phosphate and 2% urea can be sprayed on the leaves for 1~2 times, which can protect the roots and leaves and improve the seed setting rate and full fruit rate.
