Peanut fruit ripening period management technology

The full-fruit ripening period of peanuts means that half of the plants have full pods until the majority of the pods are full and full, and the varieties are different in duration, the precocious ones are shorter, and the late maturity is longer. The added fruit weight during this period was over 60% . In this period, strengthening field management can greatly increase production.

 

The growth of the main stem and the growth of the lateral branches gradually stagnated, and the nutrients accumulated in the vegetative organs rapidly transferred to the reproductive organs, accelerating the fullness and fullness of the pods, and the middle and lower leaves gradually yellowing. During this period, the vegetative growth was stagnant and the reproductive growth was gradually strong.

 

Watering

 

This period is mainly based on reproductive growth, accounting for 22-32% of the total growth period , and it is appropriate to maintain 50%-60% of the maximum water holding capacity in the field . If it is less than 40% , it will seriously affect the fullness of the pod, resulting in reduced yield. It is considered to be one of the key periods of water demand; if more than 70% is also unfavorable for pod development or even mildew and deterioration, the short dormancy period will cause the pod to lose its economic value and reduce yield in the soil.

 

Fertilization

 

At the same time, this period is also a critical period for fertilizer. After the peanut enters the ripening stage, the ability of absorption and nitrogen fixation is weakened, often leading to early defoliation due to de-fertilization, and the ability of leaf surface absorption is enhanced in the later stage. Nutrients are supplemented several times in time, and phosphorus and calcium are sprayed. The main foliar fertilizer, or the nutrients required for the comprehensive supplement of the crops, is high in absorption and utilization.

 

 

Disease prevention

 

Leaf spot disease is one of the main causes of premature aging of peanuts. Once it spreads rapidly, it often falls off a large number of leaves in a few days, causing early decay of production. It can be sprayed with “Peanut formula first person Liu Zhaobao peanut three times medicine”, the third time Prevention and treatment, no premature aging to improve the peanut fullness rate is a strong guarantee.

 

Drainage

 

In the late stage of peanut growth, there is more rainwater, and there is too much water in the ground and the soil tillage layer. It is also one of the causes of early defoliation. In severe cases, it may cause rotten fruit loss, and it is necessary to eliminate field water and plough layer diving in time.
