掌握花生的适宜采收 period 对于提高花生产量和质量具有重要关系。在采收花生时，必须注意种子的选择，以确保花生在来年能够丰收。花生的适合采收期和保留技术如下：
首先，及时采收。由于花生是在地面开花、地下成长的作物，外部难以判断荚果是否饱满成熟。同时，花生持续开花、持续结荚，因此荚果的成熟度也不一致。采收过早或过晚都会影响产量和质量。因此，确定花生的适宜采收期尤为重要。通常，花生的适宜采收期可以从以下三个方面看出。
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.
