Rice field cultivation management technology

After rice is planted, it enters the field management stage. As the saying goes, “three points are planted in seven points,” and whether management techniques are in place or not has a great impact on the yield. The core of Daejeon’s cultivation and management is “reusing fertilizers as early as possible”. This can promote the early growth of young seedlings, promote effective early delivery and lay the foundation for high yield. (1) After the planting, keep the “inching water” in the field, which will help turn green seedlings back to green. (2) After 5 to 7 days after planting, re-apply "sub tiller fertilizer." For the poor quality seedlings transplanted, the emergence of the field for seedlings can be extended appropriately. (3) “Sub tiller fertilizer” is mainly based on the application of quick-acting fertilizer ammonium bicarbonate, and the application amount shall account for 40 to 50% of the recommended amount of soil testing formula. General field block ammonium bicarbonate 30-35 kg / acre, general calcium 30 kg / acre; high yield field ammonium bicarbonate 35-40 kg / acre, calcium 30-30 kg / acre, mixed application. (4) The method of “fertilizing manure” using a combination of chemical fertilizers, insecticides, and herbicides is commonly referred to as “three guns ring together”. At the same time to achieve the purpose of fertilization, insecticide, weeding, improve labor efficiency.

Plant extract is a kind of product that takes plant as raw material, uses appropriate solvent or method. According to the use needs of the final product, through physical and chemical extraction and separation process, directional acquisition and concentration of one or more effective components in plants, without changing the structure of its effective components. The product concept of plant extracts is relatively broad. According to the different components of the extracted plants, they form glycosides, acids, polyphenols, polysaccharides, terpenoids, flavonoids, alkaloids, etc.
