There are many peanut growers who say that when they harvest their own peanuts, there are many fruit pods. However, there are many empty shells or seeds that are not full. Their occurrence seriously affects the yield of peanuts. The key is that when farmers grow peanuts, There is no less watering, no fat, and planting soil is OK. But there is still a shell phenomenon. It really kills the peasants. I don’t know where the problem has occurred. So how do you prevent this peanut empty shell or not full? Let's take a look today. What are the reasons for the appearance of peanut shells? Peanut shell phenomenon is caused by many reasons, related to peanut varieties, soil acidity and alkalinity and climatic conditions. These factors are controllable factors, as long as the growers can prevent them before they grow peanuts. Today, Xiaobian mainly talks about the phenomenon of peanut shell caused by fertilizer deficiency, and this reason can be prevented in the peanut management process. Peanut empty shell or grain is not full due to calcium deficiency and boron deficiency. Peanut deficiency and boron deficiency can cause poor development of peanut pods, affecting grain development, delaying flowering and affecting pod formation. Therefore, we pay attention to peanut planting management process. The use of calcium and boron fertilizers can completely reduce the shelling rate of peanuts, thereby increasing peanut yield. So how do farmers add calcium and boron fertilizers to reduce the shell rate? 1. Add organic fertilizer Organic nutrients are all nutrients, which can provide peanuts with all-round nutritional supplements. It is recommended that farmers with conditions can increase the application of 1500 to 2000 kg of decomposed organic fertilizers as a base fertilizer in an acre of land, especially for heavy-duty plots. 2. Increase the application of calcium fertilizer According to the acidity and alkalinity and the degree of barrenness of the soil block, we can choose the fertilizer needed. Generally, the amount of superphosphate applied per acre is 25~35 kg. When planting peanuts, it can also be used to apply 30 kg of calcium sulfate in the peanut needle. To supplement the calcium needed for peanuts. 3. Foliar spray The three times of peanuts are necessary for farmers in the peanut planting management process. Therefore, it is recommended to add calcium and boron fertilizers during the pre-peanut and the lower needle period. Generally, the soil uses 0.2% in the initial flowering period. The borax solution can be used for 2 to 3 times of top dressing. Usually one acre of land, 16L sprayer with 30 grams of water spray can be used, it is recommended to use once in the pre-emergence and before flowering, can increase the yield of peanuts 10%. If it is the peanut shell caused by premature aging of peanuts, how to prevent it? At the same time, peanut premature aging is also the main cause of peanut yield reduction. In addition to scientific fertilization and suitable watering, in the later stage of peanut, it is recommended to spray 0.2% urea and potassium dihydrogen phosphate on the foliar surface, 2~3 times, preferably every Spray once every 7 days. At the same time, reasonable control is carried out. Unsuitable control of Wang is easy to cause premature aging of peanuts, which in turn affects the normal development of peanuts. It is recommended that everyone control the use of uniconazole, although the price is higher than paclobutrazol, but the safety is better, and it is not easy to cause phytotoxicity. The standard for controlling Wang is that peanut meal is not more than 40 centimeters. It is easy to cause dead seedlings too early, and it is too late to increase production. As can be seen from the above, the daily peanut peanut shell may be related to fertilization and premature aging. For farmers, if there is a shell phenomenon in peanut planting, it means that the yield is low, which directly affects the income of farmers. Therefore, farmers must pay attention to the phenomenon of peanut shells. The specific prevention measures can be based on the contents of Xiaobian. .
