Proper sowing: seed dressing with a new high-fat membrane before sowing can repel underground pests, isolate virus infection and increase seed germination rate. The spring can be divided into two sowing dates: from late January to early February sowing, to use plastic film and small arch shed cultivation; in late February to early March sowing, to use plastic film cover cultivation. According to the spacing of 20 cm, ditch and sowing, each trip 5 lines, ditch depth 2-3 cm, with 300 grams per acre species, after sowing cover soil.
Small shed management: take mulch and arch shed cultivation. When the carrot emergence rate reached more than 50%, the seedlings were taken out of the membrane, and then the soil was compacted along the roots of the seedlings with fine soil, and then covered with a small greenhouse film. In mid-March, the temperature in the shed should not exceed 30 degrees. When the temperature is high, the leeward side must be opened to open the gap for ventilation. After the frost in early April, the shed was removed.
Growth management: suitable time seedlings, according to the growth of radish, to ensure a reasonable supply of fertilizer and water, and spray a new high-fat film, to protect the fat retention. At the seedling stage, the fruit is sprayed on the soil to strengthen the nutrient matching function, provide nutrient delivery volume, and prompt the radish to quickly and evenly expand. Timely cultivating and weeding keep the soil loose. In order to prevent the appearance of a blue head, it is advisable to tear off the mulch when the carrots are uncovered, and use the fine soil to remove the roots so that the shoulders are not exposed on the soil surface.
Pest control: Pests and diseases that damage carrots include root-knot nematodes, aphids, black rot, and black spot diseases. In the initial stage of disease, spray the targeted fungicides or insecticides with a 500-fold solution of new high-fat membranes to prevent and control disease. Insects feed on signals and weaken the media, resisting and defending against natural environmental disasters. Reduce pesticide toxins and increase the effectiveness of pesticides or fertilizers.
Polyethylene wax (PE wax), also known as polymer wax abbreviation polyethylene wax. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of wax as an additive can be directly added to the polyolefin processing, it can increase the gloss and processing properties of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax is intermiscible with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber, butyl rubber. It can improve the fluidity of polyethylene, polypropylene, ABS and demultifying property of polymethacrylate and polycarbonate. Compared with other external lubricants, polyethylene wax has a stronger internal lubrication effect.
