When will the peanuts ripen? A sign of peanut maturity.

Peanut is not only a very common crop in China, but also a very important oil crop. There is a wide range of planting areas in China, and the yield of peanuts is very high. When planting, we should pay attention to the timely harvest of peanuts. If the harvest time is inappropriate, it will have an impact on the yield of peanuts. So when will peanuts be harvested? The following editor brings you the symbol of peanut ripeness, let's have a look!

First, maturity time

The ripening time of peanuts is different. According to the planting area of peanuts, planting time and other factors. And the cultivated peanut variety is also one of the main reasons that affect the maturity of peanut. Under normal circumstances, the growth cycle of peanuts is about 3-5 months. And if they are middle-and late-maturing peanut varieties, then the ripening time is generally a little longer, about half a year. In addition, if the planting is early, then the harvest time will be early, on the contrary, it will be late, which should be paid attention to when collecting peanuts.

II. Signs of maturity

1. Plant appearance

After the peanut matures into the harvest period, the plant, stem and leaf will have great changes. According to the appearance of the plant, the diurnal opening and night closing phenomenon of the upper leaves of the plant will gradually disappear, or become insensitive. The leaves in the middle and lower parts will begin to change color and gradually turn yellow. The color of the stem will gradually change to yellowish green and begin to wither and soften. Because of the softness of the plant, the plant will change from compact to loose. If you look carefully, the plant still shows signs of lodging, and this time represents the maturity of peanuts, but also to the best time for peanut harvest.

2. Pod maturity

We also need to judge whether peanuts are mature or not according to the maturity of peanut pods. If the variety is different, the judgment standard is also different. For example, if it is a small fruit type of early-maturing peanut varieties, then the fullness rate should be more than 75%. On the other hand, the full fruit rate of mid-mature varieties of medium-fruit type should be 65%, and that of ordinary late-maturing varieties should be 45%. Careful observation of the pod, there is an obvious net pattern, the internal sponge layer gradually shrinks and ruptures and the kernel is full, then it should be harvested in time. If the harvest is too late, it will have a great impact on the quality and yield of peanuts.

3. The harvest time varies with different conditions.

In addition, we have to determine the picking time of peanuts according to the actual situation of peanuts. For example, if you want to take the soil fertility and planting varieties as the standard, then the poor fertility of barren land and early-maturing varieties generally have to be harvested first. On the contrary, the plots with good fertility and late-maturing varieties should be harvested late. If you want to keep your own seeds, the peanuts will be harvested earlier than the commonly used peanuts. During harvest, we should pay attention to good weather changes, avoid rain, prevent peanuts from getting wet, and reduce planting efficiency. And because the pod water content of fresh peanuts after harvest is as high as 50%, in order to prevent mildew and rot, it should be dried in time.

The above is a brief introduction of when peanuts mature and the signs of peanut maturity. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
