Ten kinds of cottonseeds should be used for planting

First, the severe disease of cottonseed wilt disease, Verticillium wilt is a chronic disease that restricts cotton production, and cottonseed is the carrier of pathogens, the bacteria can spread rapidly with the cottonseed, so the cotton seed in areas with severe wilt disease, verticillium wilt, Can not be transferred to the light cotton area, but can not be transferred to disease-free cotton area. Second, the pre-fushi and late-autumn peach cottonseeds Fuchi and late autumn peach growth maldevelopment, poor maturity, boll weight, seed germination rate is low, growth is weak. The third is to remove the peach buds of cottonseed Some cotton farmers for the development of a more full-fledged peach, still have the habit of robbing peach buds. All cottonseeds that have taken out peach shoots cannot be grown because they are not fully mature. The fourth is that spraying ethephon on cottonseed and spraying ethephon can promote the early maturing of cotton for 3 to 4 days, but the damage to cottonseed is large, which results in incomplete development and cannot be planted. Fifth, the degraded cotton varieties are out-of-breed crops. The out-cross rate is about 8%. Some cotton farmers have not changed new varieties for many years. The purity of cotton varieties is only 70%-80%, and the quality is seriously degraded. Continued use will lead to a reduction in production. Decline in quality. Sixth, cottonseeds stored together with pesticides and chemical fertilizers Some farmers often store cottonseed with pesticides and chemical fertilizers in a warehouse for a long period of time. Due to poor ventilation, toxic gases emitted from pesticides and chemical fertilizers can damage the normal physiological function of cottonseeds, resulting in a sharp germination rate. Less. Seventh, the storage age of cottonseed stored for more than six months is generally more than 80%. In the absence of low-temperature refrigeration equipment, the lifespan of cotton seeds is inversely proportional to the storage age. That is, the longer the storage age, the shorter the life of cotton seeds. . Eightthly, cottonseeds that have been sunburned on the cement drying field are exposed to cotton seeds with high water content on the cement drying field, which can easily cause the physiological dysfunction of the cotton seeds. Part of the cottonseeds are dull and their germination capacity is lost. Nine is the coating cotton seed that the mechanical damage is overweight cotton seed finishing, the mechanical damage rate should be controlled within 2%. Seeds with more than 2% seedbreaking rate are heavily affected by drugs and have a great impact on the germination rate. If the rate of seedbreaking is too high, it is not suitable for seed use. Tenth, degraded seed cotton seed often found in large and white hairy white seeds and hairless light seeds, thin hair seeds, green seeds, thin green seed, seed, etc., these are degraded seeds, the comparison of long fibers above Short, poor quality. Using these seeds to sow the resulting offspring, the yield is reduced and the quality of the fiber is reduced. Therefore, a strict selection must be made before sowing to eliminate these seeds.

The best quality red Fuji apple with a diameter of 80mm is selected. Natural green, pollution-free, sweet and juicy pulp, high quality red Fuji.

Organic apple, as its name implies, is from the organic agricultural production system, according to the organic certification standard production, processing, and certified by the independent organic food certification body and Apple products. Apples produced according to the organic food planting standards and production and processing technical specifications and certified and certified by the organic food certification organization. In the process of production and processing of apple, the use of synthetic substances such as pesticides, fertilizers, herbicides, synthetic pigments, hormones and other synthetic substances are absolutely prohibited, which conform to the requirements of the ecological system.
