Imported Bio-based Stabilizers Broadly speaking, stabilizing chemicals that increase the stability of solutions, colloids, solids, and mixtures are called stabilizers. It can slow down reactions, maintain chemical equilibrium, reduce surface tension, and prevent light, thermal, or oxidative decomposition. Generalized chemical stabilizers come from a wide range of sources, mainly according to the design purpose of the formula designer, you can flexibly use any chemical to achieve the purpose of product quality stability.

Author: Wangchong Fu et de force premature aging is a common phenomenon paddy crop sowing rape plate cultivation is the main obstacle to limit further enhance seed yield and quality of. Insufficient basal fertilizer, no timely topdressing, soil compaction, poor root extension, excessive planting density, uncoordinated population and individual growth, lack of nutrients, unbalanced nutrients, drought or waterlogging, frost damage, pests, etc. Get rid of premature aging. The rape leaves with senescence and premature senescence are purple or purple green, the new leaves are small and straight, the leaves are thin, the leaves are few; the stem base is small and thin, the bark is shrinking, the skin color is blue with purple, sometimes the plants are atrophic; the root group is stunted Roots stretched poorly, roots and crowns were not prosperous, and even black roots appeared; growth was slow, and normal field plots usually require 8 to 10 days for a true leaf and 14 days for a power-off field plot. To prevent premature dehydration of direct-seeded rapeseed in paddy field, measures should be taken such as reasonable dense planting, cultivating loose soil, spring fertilizer application, removing gully root, dressing fertilizer outside roots, and preventing and controlling pests. Proper close planting and reasonable close planting can reach seedlings, seedlings, and seedlings, and give full play to the advantages of groups and individuals. The planting density was determined based on the difference in rapeseed varieties and soil fertility. The hybrid varieties were smaller than the conventional varieties, and the high fertility field blocks were smaller than the middle and low fertility field blocks. Hybrid rape varieties were planted in medium soil fertility plots, conventional varieties were planted in high fertility plots, and planted 9000-10,000 plants per acre; mid-low fertility plots were planted with 10,000-1.2 thousand plants per acre. The cultivator loosens the soil and fertilizes the seedlings in the middle of the hour, promotes the occurrence and subduction of secondary roots in the middle and late stages, increases the proportion of new roots, strengthens the vitality of the roots, and controls the ability to resist lodging in the middle and late stages. Spring fertilizer Lashi according to the situation of rapeseed deficiency, targeted nutrition supplements. Appropriately increase the amount of fertilizer, increase phosphorus and potassium fertilizers and boron fertilizer, and promote steady growth. The returning green manure and manure used in the spring will be applied in the winter. The urea per hect may be 10-15 kg, the superphosphate 20-30 kg, the potassium chloride 7-8 kg, and the human waste 250-350 kg. , Or 25% compound fertilizer 25 to 30 kilograms, 7 to 10 kilograms of urea, 250 to 350 kilograms of human waste, plus water pouring. After clearing the roots of the gully, it is necessary to dredge the “three ditch†two or three times before returning to the green convulsions after freezing to ensure that there is no stagnant water in the fields during rainy weather. At the same time, the loose soil in the ditch covers the roots of the roots between the rows and promotes the stable growth of the roots and prevents lodging. Outside the root topdressing fertilizer top dressing, can supplement the lack of nutrients caused by long flowering knot angle, so as to increase the number of pods and increase grain weight. In general, 0.5% urea aqueous solution and 0.2% to 0.3% potassium dihydrogen phosphate solution 50-60 kg are sprayed per mu. Disease Prevention and Control Pest control attention to rape sclerotia, aphids, cabbage caterpillars and other pests and diseases.
