What causes the low peanut yield?

In the process of peanut planting, seedlings died and the yield was low. For various reasons, we should separate them.

Let's talk about the soil where peanuts grow. Soil is the key to plant growth, and the most suitable soil for peanut planting is sandy soil. Sandy soil has good permeability and low residue, and peanuts are suitable for absorbing nutrients and expanding fruits in this soil. The ph value of most sandy land is also suitable for peanut growth, about 6.8~7, which is more suitable for peanut to absorb nutrients.

There are many reasons for the birth and death of flowers, such as continuous cropping and soil acidification, which make the roots unable to absorb nutrients. Herbicide can also cause dead seedlings, so everyone must pay attention. In the process of peanut continuous cropping, a large amount of chemical fertilizer is generally used as base fertilizer, which causes soil pollution and acidification, and the root system of peanut seedlings is inherently weak and easy to cause death.

Peanuts also die during their growth. Mainly infected with root rot and underground pests. Dipping roots with bright shield or metalaxyl before planting can prevent root rot. The birth and death of flowers are mainly the problems of soil and roots. Roots can better absorb nutrients, which will reduce the number of dead seedlings.

There are also many reasons for the production of peanuts. For example, the variety of peanuts is particularly critical, and the yield of good varieties is naturally high. In the process of planting peanuts, we must bear in mind that when using base fertilizer, we must make good use of medium and trace elements. Peanut grains lacking medium and trace elements are not full, which easily leads to a decline in yield. At the same time, when using base fertilizer, a certain amount of diammonium phosphate and potassium fertilizer can be added appropriately.

Diammonium phosphate can promote root growth and better absorb nutrients from soil. Potash fertilizer for peanuts and tubers can be supplied from the beginning, so that the fruit can be absorbed better and faster and the yield can be increased. In the later stage of peanut fruit expansion, potassium dihydrogen phosphate can be sprayed on the leaves to promote the absorption of phosphorus and potassium fertilizer. Adequate nutrient supply will make peanuts high yield and high quality. When the soil temperature is stable above 15℃, it is suitable for sowing, the sowing depth is about 5 cm and the plastic film coverage is about 3 cm.
