How to master mechanical weeding techniques?

1) Closing and weeding: Before sowing, the big ducklings are installed in the cultivator, and the wing-shaped teeth are allotted to fully close the shallow cultivating and weeding. After the cultivator is towed with nails, the soil is crushed and flattened after cultivating. To protect droughts and improve drought control, the grass-killing effect can reach more than 85%, especially in severe weeds. 2) weeding weeds: divided into seedlings before and after the seedlings. Pre-emergence: It is the use of light or medium-sized nails for weeding, using the difference between the fragile period of weed growth (white bud single root) and soybean emergence. Miao Qiang has the advantage of less injury and more grass. Before using the seedlings must catch three links. One must be timely, that is, in the germination of soybeans to the cotyledon arch, from the surface 2 cm below the time; second is the selection of suitable equipment, according to the degree of tightness, ground pine used light equipment; hard to use medium-sized nails; Is to adhere to standard operations, seedlings in the direction of rampant or cross-cutting as well, should not Shunshun. Post-emergence spasm: It is a weeding method that must be adopted in the case of severe grassland shortage and should not be widely used. 3) Mongolian soil: It is a weeding measure that uses the characteristics of strong bean sprouts' arching ability and weak weeds' arching soil. It is an emergency method to suppress grassland and fight for grassland initiative in the event that the grass and seedlings are brought together. If the soil is high in humidity, the soil is heavy and the quality of the soil is poor, this method should not be used. 4) Weeding between the seedlings: In the soybean seedling stage, the cultivator is used for cultivating the eye mower and weeding the grass while weeding. This measure has the characteristics of loose seedlings, soil, elimination of seedlings, and less injuries. Weeding between the seedlings, we must grasp the timing of weeding according to the conditions of the seedlings, the grass and the lyrics. The depth of tooth decay, generally 2-4 cm is better, too deep injury more than seedlings, superficial shallow grass killing effect. 5) cultivating soil (1) Number of cultivating: Soybean cultivating times, usually 3-4 times. The first cultivator was conducted when the first compound leaf was unfolded; the second cultivator was conducted when the plant height was 25-30 cm; and the third cultivator was conducted before mulching. The number of times and time are not fixed. It is necessary to be flexible due to the conditions of grass, seedlings, and weather conditions. (2) The depth of cultivator: The first cultivator depth should be 15-18 cm, or 18-20 cm deeper than the furrows. The ditch and ridge should have thicker live soil layers. The dust plow soil should not be less than 5 cm. . The depth of the second cultivator should be 8-12 cm. This cultivator can be operated at high speed to increase the effect of pressing the grass between the soil and the seedlings. The third time is still 8-12 centimeters. It is better to keep the soil clean and prevent the roots from being damaged or cultivated into small ridges to facilitate mechanical harvesting. However, in the low-lying areas, attention should be paid to high ridges to facilitate drainage. The depth change of the above three cultivators is generally deep- shallow- shallow. (3) Cultivators: Qiyu Plow Type III, Sanyu Plow, etc. 6) Medicinal herbicide: Herbicide is sprayed or sprayed by hand to achieve the purpose of eliminating weeds.

Remove dirt and excess oil within the pores, and remove aging skin, making skin fresh and clean. Mask hydrating agent, will lock the moisture in the membrane, soften cuticles and help the skin to absorb nutrients, Mask quickly soothe the skin, eliminate fatigue and restore the skin's luster and elasticity. Pristine liquid containing plant extracts to soften skin tissue, promote skin metabolism, for dry or dehydrated skin. White Water mask can thoroughly remove dead skin cells, while having clean water and instant whitening effect, make the skin smooth and reproduce young, white and transparent.


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.
