Peanut calcium deficiency easy shell
Peanut products are one of the foods that people love very much. The demand for peanuts has increased year by year. When growing peanuts, the shell ratio is relatively high, which directly affects the output and quality of peanuts. The cause of peanut shells is related to the variety. Generally large peanut series easily produce empty shells, while small peanuts pearl series rarely appear empty shells.
The more important reason for peanut shells is caused by calcium deficiency. Peanuts are hi calcium crops and require about 2.7 kg of calcium for each 100 kg of pods produced. In particular, the development of pods requires calcium to enrich the kernels in order to increase the fullness. After the calcium deficiency of peanuts, the development of pods is poor, affecting the development of kernels and forming empty shells. The causes of calcium deficiency in peanuts are as follows:
(1) Soil factors. One is the lack of organic fertilizer in the soil, but do not pay attention to calcium fertilizer application, resulting in calcium in the soil, causing calcium deficiency. The second is the acidic or acidic soils such as red soil and yellow brown soil. The active calcium contained is generally low, showing calcium deficiency.
(2) Climate factors. High temperature and rain cause loss of calcium in the soil. Drought or water in the soil can impede the absorption and utilization of calcium in the root system.
(3) Excessive potassium. Excessive application of potash will affect the absorption and utilization of calcium in the roots, resulting in calcium deficiency in peanuts.
(4) Calcium deficiency in the fruit layer. Peanuts are hi-calcium, and their ability to absorb calcium in roots is limited. Especially after the flowering period, a large amount of calcium needed for the growth and development of peanut pods mainly depends on the absorption of calcium from the soil by the fruit and young fruit itself. Therefore, after the needle is in the crusting stage, even if the underlying soil layer in the root system is not deficient in calcium, the lack of calcium or insufficient calcium in the layer of soil where the fruit is located will also affect the formation of pods, resulting in the empty shell of the peanut.
In addition, there are too many nitrogen fertilizers. In order to increase yields, some farmers are blindly applying nitrogen fertilizers instead of phosphorus, potash, and organic fertilizers. This is not conducive to nitrogen fixation in root nodules, but it also leads to long-term growth of the shoots and overgrowth of stems and leaves, and insufficient nutrition in the underground. Will produce empty shells.
Organic mung bean starch is a kind of powder formed by the precipitation of mung bean after soaking and grinding with water. Our organic mung bean starch follows the traditional processing ideas and combines modern industrial technology to achieve a more efficient, safer, and more hygienic processing level. The characteristics of mung bean starch are sufficient stickiness, low water absorption, white and shiny color.
Mung bean (Vigna radiata) is a plant in the legume family. Mung beans are mainly grown in India, China, and Southeast Asia. The Chinese have grown mung beans for nearly 2,000 years. They are ubiquitous in China, and there are many types, and numbers. Mung beans are also grown in other countries/regions in South Asia, North America, Brazil, and Europe. The main provinces for mung bean cultivation in China are Anhui, Henan, Hebei, Hubei, Liaoning, Shanxi, Shaanxi, and Sichuan.
The nutritional value of mung bean starch is very high, and its uses are also very wide. For example, mung bean starch has antibacterial, antibacterial, hypolipidemic, antitumor, and detoxification effects.
Mung bean starch contains a considerable amount of oligosaccharides (pentosan, galactan, etc.). These oligosaccharides are difficult to be digested and absorbed because the human gastrointestinal tract does not have a corresponding hydrolase system, so mung bean starch provides a lower energy value than other grains and has an adjuvant therapy effect for obese and diabetic patients.
