Although the application rates of boron and molybdenum fertilizers are small, their physiological effects and yield increase effects cannot be underestimated. In the high-yield areas of peanuts, there are various levels of trace element deficiency, which has become a non-negligible factor in limiting peanut production. Therefore, in the fertilization of peanuts, the use of large and medium-sized elements and trace elements should be applied in order to achieve the purpose of increasing the output of peanuts. Organic Rice
refers to the Rice planted in the process of planting rice, using
natural organic cultivation methods, and completely using natural
farming methods. Organic rice must be a good
quality rice variety recommended by the planting improvement field, and
chemical fertilizers, pesticides and growth regulators cannot be used
during the cultivation process. Organic Rice Organic Rice,Organic White Rice,Gift Boxed Organic Rice,Golden Gift Box New Rice Ningxia Saiwaixiang Food Co., Ltd. , https://www.nxswxfood.com
Micro-fertilizer has a very important role in the growth and development of peanuts. Reasonable application has the effect of low input and high output. Although farmers understand this, they are blind when applying and often do not achieve the purpose of increasing production. Therefore, in the production practice, it is necessary to apply scientifically according to the demand of peanuts for micronutrients. Boron fertilizer: The commercial boron fertilizer is mainly boric acid and borax, which can be applied to the base and foliar spray. When the critical value of boron deficiency in soil is 0.5%, 500 grams of boron fertilizer is applied per acre. When applying basic fertilizer before planting peanuts, it is mixed with large and medium-sized elements or high-quality farmyard fertilizers. The application of boron fertilizer once at the first flowering stage and full flowering stage of peanuts can increase production by more than 16.8% per acre. Molybdenum fertilizer: Commercial molybdenum fertilizer is mainly ammonium molybdate, which can be used for seed dressing and foliar spraying. The seed dressing concentration is 0.2%. The 0.3% ammonium molybdate solution was sprayed once on the first flowering stage and the full flowering stage of the peanuts, and the yield increase effect was especially obvious. The yield per hectare increased by about 20%.
