Why are the latest peanuts aged prematurely?

Peanuts and melon seeds in our country's status is similar, are very common small snacks and food to entertain guests. However, peanuts are still one of the most important oil plants in China, so the planting area in China is very extensive. But as peanuts grow longer, the problem of premature senescence becomes more and more serious. Premature senescence can make all functional leaves of peanut wither early, and the stem will die. What causes premature peanut aging? Let's take a look below!

1. Single variety

The variety is single, and the same variety is used for too long, which makes its species degenerate, and its resistance decreases seriously or even loses. Because peanuts are a conventional seed, there is no need to change seeds every year, and peanut seeds are relatively expensive, many farmers keep their own seeds for standby, a few years do not change seeds. Even if they changed seeds, they would not buy a large number of seeds. They would try a small amount of seeds first, and then keep their own seeds, so as to cycle. Many farmers are like this. For several years, only one seed has been planted, resulting in the simplification of varieties. The genetic genes are worse year by year, and finally the resistance is completely lost, which will definitely cause premature senescence of peanuts.

2. Nutrient imbalance

The imbalance of nutrient ratio in soil or the lack of timely topdressing in the middle and late stages of planting, especially the lack of trace elements such as calcium, did not supplement in time, resulting in serious reduction of peanut resistance. Although everyone now fertilizes peanuts and has improved compared with before, there are still many people who do not fertilize according to the fertilizer requirements of peanuts. They only know that compound fertilizer and urea need to be applied, but basically ignore the application of trace elements. Moreover, many farmers are worried that peanut growth is too vigorous to cause late lodging, only long seedlings do not bear fruit, no nitrogen fertilizer is applied, resulting in serious fertilizer shortage and poor growth and premature aging of peanuts.

3. Chemical weeding

Many friends will use acetochlor to remove weeds, and it is a long-term excessive use, causing peanuts to suffer phytotoxicity at the seedling stage, and the growth and development of roots are seriously hindered. Later, they die because of premature aging of their roots. Acetochlor does solve a big problem for farmers in weeding, but it also brings a lot of side effects to peanut growth. When farmers use it, they worry that the dosage is insufficient, or the grass will continue to grow, so they do not hesitate to increase the dosage. Such blind application of drugs will not only make peanuts suffer from phytotoxicity and premature aging, but also make weeds produce certain resistance, and have no effect on weeds in the later stage.

4. Improper hormones

Peanut is a kind of crop with vigorous growth. In order to prevent peanut from flourishing, growers will use multi-effect fruiting to control peanut growth, although it will have certain effect. However, multiple-effect fruiting not only controls the growth of stems on the ground, but also inhibits the growth of roots and fruits underground. Experiments have shown that the use of multi-effect fruiting control of the growth of peanuts relative to the use of multi-effect fruiting peanuts, premature mortality is higher. Therefore, when controlling the flourishing of peanuts, it is necessary to control the flourishing and prevent the premature aging of peanuts in the later stage.

The above is the reason for premature senescence of peanuts. The premature senescence of peanuts will seriously affect the yield and quality of peanuts, and finally directly affect the economic interests of farmers. To select disease-resistant varieties, pay attention to changing seeds, do not plant the same seed for several years in a row. Balance fertilizer, control acetochlor dosage, but also need scientific and reasonable use of multi-effect triol, to control prosperity and prevent premature aging win-win.
