Mastering the proper harvest period of peanuts has a great relationship with increasing the yield and quality of peanuts. While harvesting peanuts, we must pay attention to the selection of seeds to ensure that the peanuts will be harvested in the coming year. The suitable harvesting period and retention techniques for peanuts are as follows:
First, timely harvest. Since peanuts are crops that bloom on the ground and are underground, it is difficult to see from the outside whether the pods are full and mature. At the same time, the peanuts are continuously flowering and continuous pods, so the maturity of the pods is also inconsistent. Harvesting too early and too late will affect yield and quality. Therefore, it is particularly important to determine the suitable harvest period of peanuts. Generally, the suitable harvest period of peanuts can be seen from the following three aspects.
1. Look at the growth period. The growth period of a typical peanut variety is about 125 days.
2, look at the temperature. If the average temperature of day and night is below 12 ° C, the peanuts have stopped growing and can be harvested.
3. Look at the plants. Under normal circumstances, when the peanuts enter the late stage, most of the nutrients in the plants have been transported to the pods. The plants are aging, the top stops growing, the upper leaves turn yellow, and the base and middle leaves fall off. At this time, most pod seeds If you are full, you can harvest.
Second, retention skills. Pay special attention when selecting seeds: choose the pods with the characteristics of this variety, the same mature, the branches are neat, and the results are concentrated and full. Plants with the following symptoms cannot be used for seeding:
1. Plants that are late in maturity. This plant was poorly developed in the early stage, and it grew too late in the later stage. This plant not only had a late result, but also had fewer results and a poor fullness.
2. Plants that are prematurely debilitated. Peanut pods are not yet mature, but the aboveground plants are prematurely declining, and the accumulation of organic matter in the kernels is not sufficient. The seeding rate is not high, but the characteristics of the variety are not lost, and the variety is degraded year by year, which directly affects the yield.
3. Diseased plants. Plants with blight, leaf spot, and flower rust disease, the pods used for seeding not only spread the disease, but also mostly pods and sorghum seeds.
