If the cultivation of the same or the same family of crops in the same field for many years will result in different degrees of decline in yield, deterioration of quality, breeding of diseases and pests, deterioration of reproductive status, etc., this phenomenon is called continuous cropping obstacles. "Valley, definitely," is the truth. The harms of planting millet year after year are mainly:
First, the serious occurrence of millet diseases is caused by continuous cropping, which forms a special soil environment, which inhibits the growth and reproduction of beneficial microorganisms, and the harmful microorganisms will multiply and the soil will change. After the millet replants, some diseases, especially the white ones, occur more severely because the disease is a soil-borne disease, and planting diseases will increase year after year.
Second, it is easy to cause grass barley grass barley grass is associated with the weeds, cereal barnyard grass buried in the soil, can still maintain the germination force for many years, as long as the soil surface can be turned to germinate, cereal barn grass more than alive, strong vitality, early maturation, Easy to threshing, so continuous cropping is likely to cause grass shortage.
3. "Autotoxicity" It is obvious that certain crops may release some substances through the aboveground leaching, root exudation, and decomposition of crop residues, which may inhibit the growth and development of plants of the same or lower locust or the same family. The phenomenon is called autotoxicity. Millet root system developed, strong suction fertilizer, planting year after year will consume a large amount of the same nutrient elements in the soil, resulting in exhaustion, resulting in imbalance of nutrients, adverse to the birth of millet, will also affect the next crop.
Therefore, millet cultivation must be carried out in a reasonable crop rotation to regulate soil nutrients, restore soil fertility, and reduce pests and weeds. Especially in the severely affected areas, it is best to plant millet three years later. The millet's top crop is the best in legume crops, corn, wheat, and sweet potatoes.
