Special fertilizer for direct seeding of lodging-resistant rice

Abstract

The invention provides a special fertilizer for direct seeding of lodging-resistant rice, and relates to the technical field of rice planting. The special fertilizer for direct seeding of the lodging-resistant rice is characterized by comprising the following components in parts by weight: 70-80 parts of organic matters, 10-16 parts of inorganic matters, 3-5 parts of microelements, 2-4 parts of chlormequat chloride, 10-15 parts of cake of camellia oleifera, 1-2 parts of potassium permanganate, 1-3 parts of potassium fulvic, 0.01-0.03 part of an organism growth regulator, and 0.1-0.5 part of a root and seedling promoter. The root and seedling promoter comprises the following components in parts by weight: 2-3 parts of ethylmethane sulfonate, 1-3 parts of brassin, 1-3 parts of quinoline carboxylic acid ethyl ester, and 1-3 parts of daminozide. The special fertilizer has good germination accelerating effect, high emergence rate, low height and deep root, has good lodging resistance and high earbearing tiller percentage, and yield and quality are improved.

Description

Technical field: [0001] The invention relates to the technical field of rice planting, in particular to a special fertilizer for lodging-resistant rice direct seeding. Background technique: [0002] The direct seeding cultivation technology of rice refers to a cultivation method in which rice seeds are directly sown in the field without raising seedlings and transplanting. Rice direct seeding has the advantages of labor-saving, labor-saving, and seedling-saving. It is a light and simplified new technology for rice farming. Direct-seeding rice is a rice farming method that directly sows rice seeds into the field without the need for seedling raising and transplanting. Direct seeding cultivation can alleviate the contradiction of seasonal labor force, save a lot of labor, reduce labor intensity, and is suitable for farmers who are in short supply of labor. [0003] However, direct seeding of rice also has many disadvantages. In the prior art, the fertilizer formula used for ...

AI Technical Summary

Problems solved by technology

[0003] However, direct seeding of rice also has many disadvantages. In the prior art, the fertilizer formula used for direct seeding fertilization is relatively simple, with more nitrogen fertilizer, the root system of rice in direct seeding fields is shallow, the top edge is strong, the straw is relatively thin and tall, and it is easy to lodging in the later stage

The land where rice is sown contains more alkaline metals or more heavy metals, which is not conducive to the growth of rice and will also reduce the quality of rice
