First, pay attention to timely sowing: planting time can be carried out in the local 10-12 days before the final frost, northern Guangdong in the lunar calendar in late February sowing, too late sowing film coating effect is not obvious. Second, pay attention to timely cover film: cover film immediately after planting, from the convenience of cutting the film and increase temperature considerations can choose 0.015-0.018 mm white film, more than 0.02 mm when the fruit needle is difficult to penetrate the film into the soil. Third, pay attention to the application of fertilizers and herbicides: To increase the application of organic fertilizer, available 1000-1500 kilograms of per acre decomposed household fertilizer mixed with 50 kg of high-concentration compound fertilizer, 0.2% urea solution can be used in late growth with potassium dihydrogen phosphate Foliar spray with trace elements. Pre-emergence herbicide can be used 50% butachlor (or 50% acetochlor) 100-150 ml or 72% dole 100 ml per acre after sowing sneezing, if the surface has grown weeds can be mixed with the right amount of future life Herbicides (Glyphosate, Homeostasis, Gram-free) Herbicide. Fourth, pay attention to water management: the appropriate humidity of the soil when sowing is to cling to the soil with your hands, release it is appropriate. In case of a cloudy season, the gutter should be drained in time to prevent rot, roots, and plant diseases from spreading; Fifth, pay attention to cutting the film in a timely manner: After the film is covered with film, the temperature under the film is as high as 50 degrees. After the peanut is sowed 7-10 days later, the cutting of the cotyledon through the topsoil must be promptly cut into the film to induce seedlings. The cutting time should be determined after the cotyledon arch breaks through the topsoil. Before the three true leaves are unfolded, the sooner the better. Six, pay attention to pest control: In the prevention and control of underground pests should consider the use of thiophanate-methyl seed dressing, when sowing granules home drug (carbazole, methyl willow phosphorus, etc.) in the cultivation of the trench; spray when used within the suction , contact with pesticides and stomach poison and both biological pesticides used for prevention and treatment. Seven, pay attention to the timely control of seedlings: 20-25 days after the beginning of flowering time when the plant seal large line control seedlings, 15% paclobutrazol per acre with 50 grams of water 50 kg spray control seedlings. Eight, pay attention to harvest, clean up the residual film: in the lower leaves fall off, the upper leaves turn yellow, the leaves of the sensory fluid movement disappeared when the choice of sunny harvest, promptly after the plastic film recycling concentrated treatment.
Imported Bio-based Plastic Additives
Plastic additives, also known as plastic additives, are compounds that must be added to polymers (synthetic resins) to improve their processing properties or to improve the properties of the resin itself. For example, in order to reduce the molding temperature of PVC resin, to make the product soft and added plasticizer; Another example is to add foaming agent in order to prepare light weight, anti - vibration, heat insulation, sound insulation foam plastics; The thermal decomposition temperature of some plastics is very close to the molding temperature, and the molding cannot be done without adding heat stabilizer. Therefore, the plastic assistant agent occupies a particularly important position in the plastic forming process. A class of auxiliary agents for plastic molding products, including plasticizer, heat stabilizer, antioxidant, light stabilizer, flame retardant, foaming agent, antistatic agent, mildew agent, colorant and whitening agent (see pigment), filler, coupling agent, lubricant, mold release agent and so on. Colorants, brighteners and fillers are not special plastics chemicals, but the general use of materials.
