Preparation method of rice lodging-resistant fertilizer

Abstract

The invention belongs to the field of agriculture, and specifically discloses a preparation method of a rice lodging-resistant fertilizer. The preparation method comprises the following steps: preparing a base fertilizer and a foliar fertilizer; wherein the foliar fertilizer comprises a nitrogen fertilizer and a phosphorus-potassium fertilizer, and the base fertilizer is a slow-release fertilizer.The preparation process comprises the following steps: 1) bonding ammonium sulfate, a silicon-calcium-magnesium fertilizer, zinc sulfate, manganese sulfate, boric acid, ammonium molybdate and ferroussulfate by using an adhesive to prepare core layer particles; and 2) preparing a coating solution from copper sulfate, potassium sulfate and chitosan, and coating the core layer particles obtained inthe previous step with the coating solution to prepare coating layers. According to the invention, two fertilizers, namely the base fertilizer and the foliar fertilizer, are respectively applied to two parts, and the applied slow-release base fertilizer only needs to be applied once, so that the loss of the fertilizer along with watering and rainwater can be reduced, the fertility, especially thefertility of silicon element, is effectively maintained, the foliar fertilizer is additionally applied, excessive one-time application of N fertilizer and the like is avoided, the lodging problem ispowerfully solved, and the yield is ensured.

Description

Technical field [0001] The invention relates to the field of agriculture, in particular to a method for preparing a rice lodging-resistant fertilizer. Background technique [0002] Rice is a kind of herbaceous rice, which belongs to cereals, and is also the most important and oldest kind of food in the rice genus, which is different from dry rice. Rice is the staple food of one-third of human beings in the world, and it is known as the "food of Asia". Rice is the main food crop in my country. The rice-based population in the country accounts for about 50% of the total population. It is also the staple food of people in southern my country. The nutritional value of rice is relatively high. Generally, it contains 75-79% carbohydrates, 6.5-9% protein, 0.2-2% fat, 0.2-1% crude fiber, and 0.4-1.5% ash. Compared with other grains, rice contains The crude fiber is the least, the starch grains are very small, easy to digest, and the digestibility and absorption rate of various nutrients...

Problems solved by technology

Excessive nitrogen supply can easily lead to excessive growth of plants, while insufficient nitrogen will reduce the photosynthesis and other physiological functions of rice plant roots, stems and leaves. Reduced resistance to external environmental conditions, triggering lodging

[0005] Many traditional planting methods are one-time fertilization, and more quick-release fertilizers are used, which can easily cause some fertilizer ingredients to be too much, while others are deficient, especially in the late growth period
