Problems solved by technology

This is mainly due to the fact that in recent years, in the process of rice production, people have relied more and more on chemical fertilizers and pesticides, and excessive chemical fertilizers and pesticides have led to the deterioration of the rural ecological environment in China, the decline in soil quality, and the weakening of crop resistance, which has a negative impact on rice yield and The quality has had adverse effects, especially the application of chemical substances, which has greatly reduced the nutritional value of rice, mainly due to the lack of some trace elements necessary for the human body. Based on this kind of thinking, after two years of field experiments, we developed A special fertilizer for rice foliage is produced, which can not only increase the yield of rice, but also improve the quality of rice, increase the nutritional value of rice, and meet people's needs

Abstract

The invention relates to a rice leaf fertilizer, in particular to a special fertilizer for rice leaf surfaces and application thereof. The special fertilizer comprises the following components by weight: 2 to 5 percent of chitosan, 7 to 12 percent of composite amino acid, 1.5 to 3.5 percent of middle-weight nutrient element, 0.5 to 1.0 percent of trace nutrient element, 2 to 4 percent of ethylene diamine tetraacetic acid (EDTA) complexing agent, 0.2 to 0.5 percent of surfactant and the balance of water. The special fertilizer for leaf surfaces is of an effective supplement mode except root fertilization, is applied in the rice production process, and plays an important role; and 30 to 40 kilograms of special fertilizer is used in each mu.

Description

technical field [0001] The invention relates to rice leaf fertilizer, in particular to a special fertilizer for rice leaf surface and its application. Background technique [0002] Over the past 30 years of reform and opening up, my country's agriculture has made significant progress. We have used 7% of the world's arable land to feed 22% of the world's population. Both the unit grain yield and the total grain output have achieved world-renowned achievements. Rice is the main crop of my country's agriculture, which plays an important role in the adjustment of my country's agricultural structure and food security. In 2010, my country's rice production has formed a rice industry with Chinese characteristics. However, with the improvement of living standards, people pay more and more attention to the quality of rice, and the process of rice production has also attracted people's attention. The problem of food safety has been placed in front of the government and the people. Th...
