First, the autumn pruning: mainly through trimming, remove the upright branches affecting the light, upright branches, increase the photosynthesis of peach leaves, so that the tree body to accumulate more photosynthetic products, for the next year flowering results nutrition. The amount of pruning depends on the age of the tree or growth potential. Second, pest and disease control: the fall of Taoyuan, early, mid-maturing fruit has long been harvested, late-maturing, late-maturing peaches are harvested or have been harvested, so generally farmers believe that the production of peaches is a foregone conclusion, but ignore the autumn pest control. In fact, the prevention and control of pests and diseases in Taoyuan are particularly important in the autumn. After the autumn weather is cold, the bacteria or spores that injure Taoyuan will shed into the soil with fallen leaves or fallen fruit, or there will be branches, bark, etc., and the weather will warm in the next year and then spread with wind and rain. Most of the insect pests also lurk overwintering adults or eggs. Scale insects, leaf miners, and whitefly are still endangered in the orchards. Serious orchards cause large areas of fallen leaves, resulting in less nutrient storage and less flower buds, affecting the annual yield. The main control methods are: 1. Remove weeds, dead branches, fallen leaves, and fruit drop in the orchard, and timely burn or bury it, reduce the amount of pathogenic bacteria, eggs, or overwintering adults. 2. Spray pesticides and fungicides in time. In autumn, the temperature is low, and the decomposition of pesticides is not thorough. Therefore, when the medicine is used in autumn, the concentration of the liquid medicine must be increased to ensure the efficacy. It is best to use insecticides and fungicides with a wide spectrum of pesticides. Third, increase base fertilizer. The autumn basal fertilization time is generally in September, and is mainly based on high-quality farmyard manure, and can be mixed with a small amount of quick-acting fertilizer or cake fertilizer. The general amount of fertilizer is 3,500 to 5,000 kilograms of fertilizer per acre, and the combined application of N, P, and K fertilizers. 100 kg or 200-300 kg cake fat. The scope of fertilization is generally performed in the soil below the peach tree branches, and is applied in full. Peach trees should not be too deep for fertilization in autumn. Generally, the depth of furrow application should not exceed 40 cm. (Jian County Rural Economics Bureau)
In agriculture, Estrous Synchronization is used (particularly in the dairy and beef industries) to facilitate breeding by artificial insemination. We have Progesterone Injection, Cloprostenol Sodium Injection and Testerone Propionate Injection and Estradiol Benzoate to solve farmers' different difficultites in aninal 's estrous synchronization.
