When will the latest peanuts mature? A sign of peanut maturity.

Peanut is a very common crop in China, and it is also a very important oil crop. In our country has a wide range of planting area, peanut yield is very high, in planting, we should pay attention to the maturity of peanuts timely harvest. If the harvest time is not appropriate, it will affect the yield of peanuts. When are the peanuts harvested? The following small series brings you the sign of peanut maturity. Let's take a look together!

I. Maturity time

Peanuts mature at different times. It depends on factors such as the planting area and planting time of peanuts. And the peanut variety planted is also a major factor affecting peanut maturity. Under normal circumstances, the growth cycle of peanuts is about 3-5 months. And if it is some of the late maturing peanut varieties, then the maturity time will generally be a little longer, about half a year. Another is that if the planting is early, then the harvest time will be early, on the contrary, it will be late, these are the things that need to be paid attention to when harvesting peanuts.

II. Signs of maturity

1. Plant appearance

Peanut in the mature period into the harvest, its plants and stems and leaves will have a greater change. Depending on the appearance of the plant, the day-opening and night-closing of the upper leaves of the plant will gradually disappear or become insensitive. The leaves in the middle and lower parts will start to change color and gradually turn yellow. The color of the stems will gradually turn yellow-green and begin to wither. As the plant withers and softens, the plant will change from compact to loose. Careful observation, the plant still has 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 judge whether the peanut is ripe according to the maturity of the peanut pod. Different varieties of words, judgment criteria are also different. For example, if it is a small fruit type early-maturing peanut variety, then the full fruit rate should be guaranteed at more than 75%. The full fruit rate of medium fruit type varieties should be 65%, and the full fruit rate of late fruit type varieties should also be 45%. Carefully observe the pod, there are obvious reticulation, the internal sponge layer gradually shrinks and cracks, and the seeds are full, then they 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. Different conditions, different harvest time

In addition, we also need to determine the picking time of peanuts according to the actual situation of peanuts. For example, if the fertility of the soil and the planting varieties are the standards, then the poor fertility of the barren land and the early varieties are generally harvested first. On the contrary, good fertility plots and late-maturing varieties should be properly late harvest. If you want to keep your own seeds, then harvest them earlier than normal peanuts. We should pay attention to good weather changes when harvesting, avoid rain, prevent peanuts from getting wet, and reduce planting benefits. And because the moisture content of fresh peanut pods after harvest is as high as 50%, in order to prevent mildew, it is necessary to dry them in time.

This is a brief introduction to when peanuts ripen and the signs of peanut ripeness. Today's introduction is here, this article is for reference only, I hope to be able to help everyone!
