Problems solved by technology

[0004] At present, the conventional fertilization of rice is mostly based on nitrogen, phosphorus, and potassium fertilizers, especially the use of heavy nitrogen fertilizers, and the use of medium and micro-fertilizers is underestimated, which has brought serious problems in agricultural production. Sufficiently meet the nutrients needed for rice growth

Embodiment 1

[0019] (1) Soil properties: the soil type is sandy soil, and the soil fertility is above average.

[0020] Rice for testing: the variety is Denong Zhengcheng Seed Industry "6326" (indica rice).

[0021] Design of the experiment: Two treatments were set in the experiment, two repetitions were made, the area of ​​the plot was 0.2 mu, and a protection row was set up in the plot.

[0022] Treatment 1: special fertilizer for rice (N, P, K content 13-7-5) 30kg / mu; topdressing urea 10kg / mu at turning green tillering stage, special fertilizer for rice (13-7-5) 15kg / mu; topdressing at booting stage Apply urea 8kg / mu. Treatment 2: basal application of compound fertilizer (N, P, K content 18-10-12) 30kg / mu; topdressing urea 10 kg / mu and compound fertilizer (18-10-12) 15 kg / mu at turning green tillering stage; booting Topdressing urea 8 kg / mu.

[0023] Other field management measures were the same.

Abstract

The invention discloses special fertilizer for rice. The special fertilizer for the rice comprises urea, monoammonium phosphate, potassium chloride, compound sodium nitrophenolate, fermented animal manure, turf, silicon fertilizer, zinc fertilizer, attapulgite and decomposed stone powder according to a mass ratio of 250:150:80:0.12:250:120:5:10:100:35. The fertilizer provided by the invention increases content of protein, amino acids, vitamins and medium trace elements such as zinc, calcium and iron, and integrates organic fertilizer and inorganic fertilizer together. By adding trace elements of the silicon fertilizer and zinc fertilizer, the fertilizer is comprehensive in nutrients, reasonable in proportions, and mutually assistant in slow-fast action; and fertilizer efficiency is stable and long. Compared with conventional fertilizer, the fertilizer provided by the invention can increase the yield of the rice by over 8%.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a rice special fertilizer suitable for rice planting areas. Background technique [0002] Rice is the most important food crop in my country. There are two peak periods of fertilizer demand in rice growth, namely the tillering period and the booting period. The level of rice yield is closely related to the comprehensive factors of rice variety, soil, climate, fertilization, water, and pest and weed control. Among these factors, the influence of fertilization on rice yield plays a very important role. This is because fertilizer is the material basis for increasing rice production, and the application of fertilizers, especially nitrogen, phosphorus, potassium, zinc, and silicon fertilizers, can greatly increase rice production. Through rational fertilization, on the one hand, the contradiction between rice growth requirements for nutrient elements and soil fertilizer supply can be coordinated to a...
