Why peanuts are aged prematurely

Peanuts have the same status as melon seeds in our country, and they are very common snacks and food for entertaining guests. However, peanut is still one of the most important oil crops in China, so the planting area in our country is very extensive. However, with the growing time of peanut planting, the problem of peanut premature senescence becomes more and more serious. Premature senescence can make the late functional leaves of peanuts wither earlier, and the stems will die. What is the cause of premature senescence of peanuts? Let's take a look at it.

1. Single variety

The variety is single, and the same variety has been used for too long, so that its species character is degraded, and the resistance is seriously decreased or even lost. Because peanuts are a kind of conventional seeds, they do not need to change seeds every year, and peanut seeds are more expensive, so many farmers keep their own seeds for reserve, and they do not change seeds for several years. Even if you change the seed, you will not buy a large number of seeds, first a small amount of trial planting, and then keep your own seeds, in order to cycle. This is the case for many farmers. Only one seed has been planted over the past few years, resulting in a homogenization of varieties, genetic deterioration year after year, and finally a complete loss of resistance, which will certainly lead to premature senescence of peanuts.

2. Nutrient imbalance

The imbalance of nutrients in the soil or the lack of topdressing in the middle and later stage of planting, especially the lack of trace elements such as calcium, led to a serious decrease in the stress resistance of peanuts. Although people now fertilize peanuts and improve them than before, there are still many people who do not apply fertilizer in accordance with the law of peanut fertilizer needs, only know the need for compound fertilizer and urea, but basically ignore the application of trace elements. And there are many farmers worry that peanut growth is too prosperous to cause lodging in the later stage, only growing seedlings do not bear fruit, no application of nitrogen fertilizer, resulting in serious lack of fertilizer and poor growth and premature senescence of peanuts.

3. Chemical weeding

Many friends will use Acetochlor to control weeds, and is long-term excessive use, resulting in peanuts in the seedling stage when the drug damage, root growth and development has been seriously hindered. In the later stage, he died of premature senility of the roots. Acetochlor does solve a big problem of weeding for farmers, but it also brings great side effects to the growth of peanuts. When using it, farmers are worried that if they do not use enough, they will continue to grow grass, so they do not hesitate to increase the dosage. Such blind use of drugs will not only cause premature senescence and death of peanuts, but also cause certain resistance to weeds, which has no effect on weeds in the later stage.

4. Inappropriate hormone

Peanut is a relatively prosperous crop, growers in order to prevent the growth of peanuts, will use multiple frustrations to control the growth of peanuts, although there will be a certain effect. However, multiple frustrations will not only control the growth of stems on the ground, but also inhibit the growth of underground roots and fruits. Some experiments have shown that peanuts with multiple frustrations have a higher mortality rate of premature senility than peanuts without multiple frustrations. Therefore, when controlling the growth of peanuts, we should not only control the growth of peanuts but also prevent the premature senescence of peanuts in the later stage.

The above is the cause of peanut premature senility, peanut premature senility will seriously affect the yield and quality of peanuts, and finally directly affect the economic interests of farmers. To choose disease-resistant varieties, pay attention to change, do not plant the same seed for several years in a row. To balance fertilizer and control the amount of Acetochlor, we also need to use multi-effect scientifically and rationally to achieve the win-win situation of controlling prosperity and preventing premature senility.
