First, increase production efficiency: generally can increase production 15% -20%.
Second, the technical points
Drip irrigation with water fertilization, uniform fertilization, reduce nitrogen volatilization and deep leakage, improve fertilizer utilization, should use "eat less and more meals," the principle of fertilization. Fertilizer 3-4 times during the whole growth period, the first topdressing, combined with dripping water, 2-3 drops of urea at the 2-3 leaf stage, 3 kg/mu of potassium sulfate, 8 kg/mu of urea during the jointing stage, and drop in booting stage Urea 5 kg / mu, filling urea, potassium dihydrogen phosphate 2 kg / mu, to prevent dry hot air, increase the weight, improve quality.
Third, pay attention to matters
1. Injecting chemical fertilizers will cause corrosion to the filters, valves, etc. Each time after the completion of injection, be sure to add sufficient time to flush the entire system. There should not be any fertilizer solution remaining in the system. Fertilizer tanks should be cleaned after each injection.
2. If a suction pump is used, the fertiliser tank is best equipped with a stirrer. Fertilizer should be mixed before each fertilizer and fertilizer to accelerate dissolution.
3, not a lot of fertilizer. With drip irrigation, it is best to use a small amount of multiple methods. Applying too high a concentration of fertilizer to the soil is detrimental to the growth of the crop.
4. All fertilizers to be injected must be soluble. Also pay attention to the reaction between different fertilizers. Precipitates from the reaction may clog drip irrigation systems. Nitrogen fertilizers rarely cause plugging. The possibility of blockage caused by phosphate fertilizers is very high. Be careful. Injecting phosphoric acid is usually the safest. Potassium fertilizers can be quickly dissolved and generally do not contain plugging problems.
Fourth, suitable areas: Wheat cultivation areas are suitable for promotion and application.
The freeze dried food is the abbreviation of vacuum freeze-dried food, also known as FD food. Due to the special place of freeze-drying.Therefore, the color, flavor, nutritional composition, appearance and shape of the original fresh food can be maintained to the greatest extent; In addition, freeze-dried products can be stored at room temperature for more than 5 years without preservatives, and the finished products are light and easy to carry and transport. It is an excellent method for processing tourism, leisure and convenient food. Freeze dried food, a former aristocrat known as astronaut food, has quietly entered people's life.
Freeze Dried Fruit uses the vacuum freeze-drying method of the freeze dryer to freeze the water in the fruit in advance, and then sublimate the frozen water in the fruit in the vacuum environment to obtain the freeze-dried fruit. In short, extract the water in the fruit at low temperature to retain its original nutrition.
Freeze dried fruit is fast freezing and vacuum ice dehydration. It preserves the original color, aroma, taste, nutrients and the appearance of the original materials. It has good rehydration and does not contain any additives. It is an ideal natural hygienic food.
The freeze dried apple slice refer to a snack which are made of apple and popular in daily life.
