Problems solved by technology

[0005] The technical effect of the present invention is: it solves the problems of raising seedlings of machine-transplanted rice in double-cropping rice areas, such as early rice seedlings are thin and weak, not easy to pack roots, easy to be infected with blight, and late rice seedlings are easy to grow excessively and aging. Special physical and chemical products for seedling raising with comprehensive effects of nutrition, chemical control, packing, and disease prevention, realizing the "fool" of machine-transplanted rice seedling raising technology

Abstract

A special nutrient for factory mechanical transplanted rice seedling rising includes a special nutrient for early rice seedling rising and a special nutrient for semi-late and late rice seedling rising. The special nutrient for early rice seedling rising comprises, by weight, 4.33 parts of monoammonium phosphate, 2.33 parts of urea, 3.33 parts of potassium chloride, 6.00 parts of bentonite, 0.21 part of thiophanate-methyl, 0.50 part of imidacloprid, 0.17 part of rooting agents and 0.017 part of uniconazole. The special nutrient for semi-late and late rice seedling rising comprises, by weight, 4.33 parts of monoammonium phosphate, 2.33 parts of urea, 3.33 parts of potassium chloride, 6.00 parts of bentonite, 0.17 part of thiophanate-methyl, 0.50 part of imidacloprid and 0.05 part of uniconazole. The nutrient is a special physical and chemical product for seedling rising and integrates supplying nutrition, chemical control, packing, disease prevention, capable of improving seedling quality and output, favorable for realizing normalization, standardization and simplification of factory mechanical transplanted rice seedling rising.

Description

technical field [0001] The invention relates to a special nutritional agent for machine-transplanted rice factory seedling raising. Background technique [0002] At present, the products used in rice seedling raising on the market are mainly paclobutrazol, uniconazole, seedling strengthening agent, dry nursery nurse, seed dressing agent, etc. Among them, paclobutrazol and uniconazole are mainly used to control the growth of seedlings; The growth is mainly strong, and the dry nurse is a slow-release fertilizer for seedling growth; the seed dressing agent is mainly for preventing diseases and insect pests. Most of the above-mentioned seedling products have single functions, and it is difficult to cultivate robust double-cropping rice seedlings suitable for machine transplanting. In the double-cropping rice area in southern my country, due to the special ecological and climate environment, machine-transplanted early rice seedlings must solve the problems of heat preservation an...
