First, there are a number of reasons for the problems: First, after the artificial harvest of rice, farmers do not sun-straw straw, more rain in autumn, straw piled up in the fields for a long time, become wet, soft, and rotten. After sowing, the straw is not covered, and the thick and solid cover of the grass will affect the emergence of the seedlings. Birds that are not covered with grass will eat it. The second is that the farmer directly spreads the ammonium bicarbonate to the field surface and then sowing, because the seeds are contacted with ammonium bicarbonate to burn seed and burn seedlings.
The reasons for the lack of fertilizer: First, farmers used ammonium bicarbonate to mix 50 kg/mu and superphosphate 20 kg/mu, and then spread the field surface directly on sunny days, and then planted. Although the amount of base fertilizer was enough, ammonium bicarbonate was rapidly decomposed. Ammonia volatilizes, resulting in severe shortage of wheat seedlings. Second, the amount of the base fertilizer itself is insufficient, if the top dressing is in case of little rain in winter, the use of urea to catch rain may not catch the opportunity of rain. Nitrogen topdressing cannot be achieved.
Second, the solution to prevent the emergence of less seedlings should be harvested after the rice, the straw picked up, sunny airing, raining and concentrated stacking, after wheat sowing, straw cover as thin as appropriate, cover uniform, strict cover, a straw covered 1.5-2 acres Mu is appropriate.
To prevent shortage of fertilizer for the prevention of burning seeds and burning seedlings, wheat is usually used as wheat-free fertilizer or compound fertilizer in order to prevent rain and water from being used in winter, and it is not convenient to top-dress fertilizer. The proportion of base fertilizer is slightly larger, and the proportion of top dressing is slightly smaller, and nitrogen is available per acre. Phosphorus, potassium ternary compound fertilizer 15 kg, urea 10 kg, and then sowing. Farmers applying ammonium bicarbonate can disperse ammonium bicarbonate in urine water or in clean water at the dosage of 50 kg/mu. The superphosphate is applied at a dosage of 20 kg/mu and then sowed. A rainy day before January to see seedlings with fertilizer once with urea 5 kg / mu.
Third, the machine received rice fields block wheat no-tillage Note: First, early removal of rice straw field, concentrated on the side of the field, pay attention to timely drying, in order to ensure adequate coverage of grass. Doing so can make the weeds in the field fully contact the herbicide liquid when weeding; secondly, it can prevent the wheat grain from falling on the straw when sowing; 3, it can avoid that the straw meets the decay of rain, and the straw is not enough when covered, and after sowing, If rice straw can be covered tightly and evenly, it will accelerate the death of weeds in the field, prevent the occurrence of weeds, and the rate of emergence of young wheat seedlings will be high. The second reason is that due to the rolling of the combine harvester, in addition to normal open trenches around the fields, it is necessary to level the fields to facilitate field drainage.
1. Decomposition: biodegradable excess body fat, flat meat, all kinds of stone decomposition, promote the decomposition of food digestion and absorption.
2. Blood purification: Arrange internal environment, purify the blood and improve physical fitness - decomposition, eliminate waste, the blood becomes acid.
3. activation: the pituitary gland to stimulate cell regeneration, a recession is not easy to remember, can not afford to skin wrinkles, youthful beauty delay human aging.
4. Anti-inflammatory antibacterial effect: enzymes can strengthen the fight against white blood cells and remove invading bacteria and purulent matter, the cells speed recovery and enhance wound healing
5. hangover, hangover prevention.
6. For picky eaters, do not like to eat fruits and vegetables children the best nutritional supplements and energy sources.
It contains nutrients more easily absorbed by the body, containing amino acids, polysaccharides, protein components, vitamins B, C, E, and trace elements needed by the body. Long-term use, long-term preservation.
Help prevent hardening of the arteries, lower cholesterol, fat decomposition and excretion of non-ferrous metals and radioactive elements and balance the body's composition, help prevent cancer and other diseases, promote blood circulation and metabolism, recuperate, enhance physical fitness, health protection.
Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
