Things like crops are not mature in the harvest season, which makes people feel anxious. However, you can't gain without familiarity, can you?
Like peanuts, because they are crops that blossom and bear fruit successively, the fruits produced on the same peanut seedling are different in the morning and evening, including fu fruit and autumn fruit. If harvested too early, some fruits are not ripe and full, and the water content is too large, which will be full after drying, which will directly affect the yield.
But if the harvest is too late, the pods will easily fall into the ground, and underground pests such as grubs will bite them. Once there is a lot of rain, the fruit is easy to rot and even germinate underground.
For example, in our place this year, in the early August of the lunar calendar, most peanuts were ripe, but it rained all day for nearly 10 days, which directly led to the peanut rot and germination in the depression.
When is the best harvest time for peanuts?
It is a great principle that the harvest time of peanuts should be judged according to the growth of plants, the development of pods and the change of local temperature.
1, plant growth.
When the top of the peanut plant no longer grows, most of the middle and lower leaves fall off, the top leaves turn yellow and the stems are yellow-green. At night, the leaves are no longer closed, which means that your peanuts will be unearthed.
I usually stand on the ground, and all I see are plastic film, furrows, and dry and sparse leaves on peanut seedlings. I looked carefully in the field, and there were only a few leaves on the top of a peanut seedling. It was time to start work.
2. Development of pods
Pull out a few peanuts in the field, and more than half (more than 80%) of the peanuts have clear lines. After peeling off the shell, you can see that the seeds inside are full and the seed coat is pink (or has the inherent color of the variety) instead of white, which indicates that it is mature.
If the shell is mostly white, the grain is unclear, the endocarp is white, not black, the seed coat is white, and the kernel is tender, it will take several days.
3. Local climate change
Some people have delayed sowing for various reasons, or because of the region and sowing season (such as peanuts after wheat), it is time to harvest peanuts, but they are not mature yet, depending on the change of temperature.
Peanut is a warm crop. When the average temperature of day and night drops to 65438 02℃, peanut pods will stop developing and will no longer grow. At this time, even if they are immature, you should pull them out, or you will be in danger of frostbite if they are late.
Whether peanuts are ripe or not depends not only on the season, but also on the growth, fruit, temperature and variety.
Why do two different peanuts in the same field ripen sooner or later at the same time?
This is mainly related to the variety. Generally speaking, the late-maturing peanuts sown in northern China have a long growth period and a late maturity time. Under the condition of timely sowing, it should be harvested before June 20th of 10.
However, some middle-maturing and early-maturing varieties are usually harvested in the middle and late September if sown in time.
Of course, due to the early sowing time and early maturity of plastic film peanuts, the harvest time will be advanced accordingly, about one month in advance.
If there is too much fertilizer, especially in plots with too much nitrogen fertilizer and organic fertilizer, the harvest will also be delayed. The peanut fields of Lao Liu's family are all planted with ginger for many years, which delayed the ripening time and delayed the harvesting time by a few days.
However, the plots with incomplete disease control should be harvested because the defoliation time is early, otherwise the fruit will drop and germinate. Land with heavy grubs should also be harvested early, otherwise it will be bitten, fruited, rotted and germinated.
The weather here is fine these days, and the autumn tiger is coming. At noon, the temperature is as high as 30℃ or above, and peanuts are everywhere.
But the colors are different, some are black, some are yellow and white, and some are colorless, because the pods are covered with mud. Although it has been unearthed, it has not been unearthed.
But the price is ok this year. Just sun 1 day is charged at about 2.50 yuan, and sun for 3 days is charged at about 3 yuan per catty. What's the price of peanuts in your place?
