Abstract
The invention discloses a compartment furrow fixed three-surround three-dimensional intensive cultivation method for rice and relates to the rice super high yield cultivation technology. The compartment furrow fixed three-surround three-dimensional intensive cultivation method for the rice comprises steps such as rice varieties selection, soil preparation, fertilization, seedling culturing, plantation, irrigation and insect disease prevention. According to the compartment furrow fixed three-surround three-dimensional intensive cultivation method for the rice, super rice varieties having high tillering capacity, being resistant to diseases and having large rice ears and high yield are selected, rice seedlings are raised in a plastic plug seedling method, furrows and compartments are formed according to fixed compartment width, the plough layer thickness is increased, the seedlings are planted in a double-triangular shape, soil testing and formulated fertilization is performed, the fertilizer is set according to production, the fertilizer is applied reasonably, meanwhile moisture balancing management is performed, roots are promoted through steam, tillering is promoted and ears are increased through roots, large ears and more grains are obtained, finally a pest and disease damage integrated control method of unifying prevention and control, integrating prevention and treatment and putting emphasis on the prevention is adopted. Compared with a traditional rice plantation method, the compartment furrow fixed three-surround three-dimensional intensive cultivation method for the rice has the advantages of enabling average rice yield of per mu to be increased by 304.1 kg and income per mu to be increased by 912.3 yuan and being remarkable in economic benefit.
Description
technical field [0001] The invention belongs to the plant cultivation technology in the field of agricultural technology, in particular to a super-high-yield cultivation method of rice. Background technique [0002] my country's current population has exceeded 1.4 billion, and it is a big food consumer. At the same time, my country's per capita arable land area is less than 1.4 mu, which is less than half of the world's per capita arable land area. As my country's economy continues to grow at a high speed, urban development and basic construction occupy a large amount of arable land, resulting in a substantial reduction in agricultural arable land in many provinces. It will be an irreversible trend for a long period of time that the population increases year by year and the area of arable land decreases year by year. It is estimated that by the 1930s, my country's population will reach 1.6 billion, and the per capita arable land will drop to less than 1 mu. How to produc...
