[0003] The Chinese invention patent with the application number 201710144850.2 discloses a special fertilizer for rice with nitrogen and potassium slow-release function and its application. Through the combination of nitrogen and potassium binary controlled-release fertilizer and other granular fertilizers, one-time fertilization prolongs the time of nutrients in water. Although it can meet the nutrient needs of rice growth, the ratio of nitrogen and potassium in the nitrogen and potassium dual controlled release fertilizer is fixed (2:1), and the release period of nitrogen and potassium in the nitrogen and potassium dual controlled release fertilizer is the same, so it is suitable for a single rice variety , not suitable for promotional applications
[0004] The Chinese invention patent with the patent number ZL201410175904.8 discloses a slow-release compound fertilizer for machine-planting rice. The coated slow-release components of the slow-release compound fertilizer include resin-coated compound fertilizer, resin-coated Diammonium, resin-coated potassium chloride, resin-coated urea for 2 months, and resin-coated urea for 3 months. Although this slow-release compound fertilizer only needs one fertilization, it prolongs the time of fertilizer supply and realizes nutrient release and crop nutrition. The advantage of synchronous absorption, but each component is resin-coated slow-release fertilizer, without quick-acting ingredients, the cost of fertilizer is too high, and the early-stage quick-acting nutrients are seriously insufficient, which will seriously affect the early tillering of machine-transplanted rice and affect the number of ears per mu. Seriously affect the output, and because of the full-coating treatment, the price is extremely high, and it lacks practical production and application value

Abstract

The invention relates to a lodging-resistant controlled release blend bulk fertilizer for direct-sowing rice. The preparation method specifically comprises the following steps: blending quick-acting nitrogen phosphorus and potassium particles, anti-floating resin coated urea and resin coated potassium fertilizer as well as medium trace elements such as boron, zinc, magnesium and the like accordingto a certain ratio, thereby obtaining the product. Due to continuous and uniform release of low-concentration nitrogen in the resin-coated urea, pitch of the rice can be shortened, inhibition of high-concentration ammonium nitrogen on root system growth is avoided, and the root system of the rice is advanced; and the resin-coated potash fertilizer can achieve effects of improving the hardness ofstraws, promoting fullness of rice grains and improving the quality of the rice. The resin urea and the resin potash fertilizer achieve a synergistic effect on the rice, the lodging resistance of therice can be greatly improved, topdressing can be decreased by 1-2 times, the fertilizer utilization ratio is improved, and the fertilizing amount is reduced.

Description

technical field [0001] The invention relates to the technical field of slow-release and controlled-release fertilizers, in particular to a lodging-resistant and controlled-release mixed fertilizer for direct-seeding rice, a preparation method and application thereof. Background technique [0002] Southern rice is one of the most important food crops in my country, and direct seeding, as a primitive rice cultivation method, was gradually replaced after the emergence of rice transplanting technology. However, due to the labor-saving, labor-saving, and cost-saving features of direct-directed rice, and the fact that direct-directed rice has no damage to the seedlings and the process of turning green after planting, the growth period can be shortened; There is no need to raise seedlings to shorten the planting time in the field. Therefore, compared with rice transplanting technology, large farmers prefer to use direct seeding to grow rice. At present, in my country, direct-direc...
