When peanuts enter the fruit ripening stage (late growth stage), the new leaves no longer increase, and the middle and lower leaves begin to turn yellow and fall off. Prevention of premature detachment of the upper middle leaves, maintaining a large green leaf area, maintaining a longer functional time; enhancing leaf photosynthesis intensity, increase photosynthetic efficiency; speed up nutrients in the stems and leaves to the pods to run, increase the operating rate when peanuts The focus of post-field management.
There are many causes of premature detachment of upper leaves in peanuts. The main ones are the premature defermentation of defertilizers, and the more severe the sandy nature; the harm of leaf spot disease, especially net spot disease and brown spot disease, will spread rapidly once they occur. Within days, a large number of leaves were shed; premature and over-spraying of the conditioners, especially BJ (P9) and P333 (PP333) and conditioners containing this ingredient, were more severe. Long-term accumulation of water may also cause early defoliation.
The prevention of early defoliation can take corresponding measures for different reasons. In general terms, it can be sprayed for 2 to 3 times with 10 to 12 days of spraying with foliar fertilizer and broad-spectrum fungicides rich in phosphorus and calcium, and it also has a certain amount of premature defoliation caused by the prevention of premature defertilization and leaf spot. Relieve the effect of delaying defoliation. The author's experiments and practices have proved that spraying Taiwan's "Jia Tai-Feng" quick-calcium or Canadian-made "Arcadian" seaweed extract or Jinan-produced "Da Di" peanuts treasure, mixed with mancozeb zinc (or Dasheng M45), Or thiophanate-methyl, etc., all have a good effect of delaying defoliation, increasing the fruit-filling index, and fruiting degree of pods. Paying attention to the discharge of water in the ground and phreatic layer diving in time is an effective measure to prevent early defoliation caused by pests.
Other Agricultural products
Agricultural products" means agricultural, horticultural, viticultural, and dairy products, livestock and the products thereof, the products of poultry and bee raising, the edible products of forestry, and any and all products raised or produced on farms and processed or manufactured products
An agricultural product is a product you get when you cultivate plants or animals to sustain or enhance human life. Food is the most widely produced agricultural product, and, in fact, the global per-person food supply (as measured in calories per person) has risen more than 20 percent in the past 50 years.
But people also use a vast array of agricultural products every day for other uses, ranging from the clothes we wear to the paper we write on.
1, [agricultural products]: in the production of agricultural items such as rice, wheat, sorghum, cotton, tobacco, sugar cane and so on.
2, according to Agricultural Product Quality Safety provisions of Article II of
agricultural products is the primary products from agriculture, that is
obtained in the agricultural activities of plants, animals, microorganisms and
their products.
3, World Trade Organization (WTO) agricultural product categories will be defined as "including live animals and animal products, vegetable products, fats and decomposition products, food and beverages." Definition of this concept is relatively broad. "PRC Agricultural Product Quality Safety" agricultural products defined as "animals, plants, microorganisms and their products directly processed." Since agricultural products are the main source of food, but also an important source of industrial raw materials, agricultural products into edible agricultural products and non-food agricultural products
