In recent years, cotton disease has become the first problem affecting cotton production, especially in the cotton seedling stage, if encountering low temperatures, rainy and other adverse climates, it is easier to cause a large area of ​​disease to occur. Miao replanted. Grasping the following points can effectively prevent the occurrence of cotton seedling disease.
I. Appropriate late sowing on the basis of deep plowing before winter, when the 5 cm ground temperature stably passes 14 °C and can quickly reach 16 °C, sowing is appropriate. Generally, the cotton film is planted around April 25th. High ground temperature can shorten the seedling emergence. Time, reducing the consumption of nutrients in the ground, is conducive to the formation of strong seedlings.
Second, the balance of fertilization and fertilization soil recommended conditions where the soil can be applied to formula fertilization, soil what elements will make up for lack of, so as to avoid economic waste. Can not measure soil fertilization recommended Mushi organic fertilizer not less than 1500 kg, base fertilizer can be used in the following formula fertilizer: General cotton field can be applied 35% (14-16-5), 30% (12-8-10) of the compound Fertilizer; 40% (13-12-15), 45% (18-12-15) of compound fertilizer can be used for old cotton fields with low potassium fertilizer in recent years; 45% of nitrogen fertilizer can be used in large quantities (15) -12-18) compound fertilizer.
Thirdly, the seed coating agent used to select coated seeds for seed coating contains various components for insecticidal, bactericidal and regulating seed growth and development. It can effectively prevent and control underground pests and kill pathogens in the soil around the seed. Can effectively reduce the occurrence of cotton seedling disease.
Fourth, after the emergence of deep cultivating cotton, in case of low temperature or after the rain should be timely and deep cultivating, which is conducive to scattered phlegm and humidity, increase soil permeability, increase the temperature, while maintaining the lower lyrical, can also stimulate the emergence of cotton roots The new root promotes its roots and raises its disease resistance.
Fifth, the use of chemical comprehensive prevention and control In order to expand the scope of sterilization, enhance control effect, can be mixed with two fungicides, while improving the growth of seedlings, promote the robust growth of cotton seedlings, can also be used with two kinds of nutrient spray. The fungicide can be used: 50% carbendazim 25 grams, 72.2% Precise 25 milliliters (to prevent cataplexy, epidemic disease mainly) 80% ethyl allicin (the product of aluminum, iron and other metals or alkaline substances can be easily decomposed Failure) nutrition regulator can be used: E lead 20 to 40 mg, brassin lactone 1 g, 85% gibberellin 0.7 to 1 g. The above amount is based on the sprayer for each 12.5 kg capacity. Pay attention to the weather information and try to spray a preventive medicine before each rain, or spray it 1-2 times in the rain.
Nuts can generally be divided into two types: one is seeds, such as sunflower seeds, pumpkin seeds, peanuts, etc.; the other is tree nuts, such as pistachios, hazelnuts, cashews, walnuts, pine nuts, walnuts, chestnuts, almonds. And the macadamia and pecans that have been very hot in the past two years. These nut foods contain more protein, calcium and a variety of vitamins, which can provide the body with a variety of nutrients needed by the brain and body.
In general, a nut is a closed fruit classification of a nutrient-covered woody or leathery hard shell. The skin is hard and contains one or more seeds. It includes two types of tree nuts and fruit seeds, walnuts, chestnuts, pistachios, almonds, etc., which belong to the fruit seed class.
