Embodiment Construction

[0033] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0034] An embodiment of the present invention provides a two-stage rice cultivation method, which mainly includes the following steps: soil preparation and fertilization, transplanting, water and fertilizer management and prevention of premature aging.

[0035] The step of fertilizing the soil preparation comprises: first irrigation and land preparation, so that the field reaches flat mud work; then apply base manure to the field, so that the ratio of the three elements of nitrogen, phosphorus and potassium in the growth period of the seedlings in the whole field is 1: 0.45~0.55:0.65~0.75, to meet the needs of optimal tiller population construction in rice. In this embodiment, in the step of fertilizing the soil, the basal fertilizer applied makes the ratio of the three elements of nitrogen, phosphorus and potassium in the growth period o...

Abstract

The invention provides a two-stage cultivation method for rice.The method comprises the steps of soil preparation and fertilization, transplantation, water and fertilizer management, premature senescence prevention and the like.According to the two-stage cultivation method for the rice, on the basis of a two-stage cultivation technology for the rice, construction of populations is formed in the soil preparation and fertilization and transplantation processes, morphology construction is formed through water and fertilizer management and nitrogen element regulation, and function construction is formed in the premature senescence prevention process, so that the dosage of fertilizer and pesticides is reduced, the fertilizer utilization rate is increased, and meanwhile yield increasing and income increasing of the rice are achieved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a two-stage rice cultivation method. Background technique [0002] Rice is the main food crop in my country, with the largest planting area, the highest yield per unit area, and the largest total output. 65% of the people take rice as a staple food. The planting area exceeds 30 million hectares, accounting for 30% of the grain planting area. The output accounts for about 40% of the total grain output. my country's rice production also plays a pivotal role in the world. China has obtained 35% of the world's rice production with 21.4% of the world's rice planting area. It has made positive contributions to ensuring global food security. [0003] Since the founding of the People's Republic of China, my country's rice variety improvement and cultivation techniques have undergone considerable development. The successful selection and application of rice dwarf varieties and ...
