Problems solved by technology

Long-term large-scale application of chemical fertilizers leads to soil compaction, deterioration of aggregate structure, decline in fertility, and deterioration of physical and chemical properties
At present, the reasonable utilization rate of straw resources in my country is low, only 20%-36% is used as feed and fertilizer, and the burned and discarded straw is as high as 45%-60%. The phenomenon of crop straw burning is serious, which not only wastes organic fertilizer sources, but also seriously polluted the environment
However, returning straw to the field is limited by the low efficiency of natural decomposition of rice straw

Embodiment 1

[0026] A high-yield planting method for double-cropping rice, comprising the following steps:

[0027] (1) Seed selection and processing:

[0028] a. The indica-type two-line hybrid rice "Lingliangyou 268" was selected for the early rice, and the three-line hybrid mid-maturing late indica "H You 518" was selected for the late rice;

[0029] b. Before sowing, sterilize the seeds with ultraviolet radiation for 30 minutes, soak them in warm water for 2 hours, and perform ultrasonic treatment at the same time, then soak them in potassium permanganate solution for 15 minutes, wash them with water, and finally mix with them in a ratio of 500:1. Lactobacillus for seed dressing;

[0030] (2) Early and late rice sowing

[0031] a. Raise early rice seeds in late March or early April. The amount of early rice seeds per acre is 2.5kg, and the seedling age is controlled at 30 days. Rotate the paddy field in the middle and late April, and then mechanically transplant the early rice seedli...

Abstract

The invention discloses a high-yield planting method for double-season rice. The high-yield planting method comprises the steps of seed selecting and processing, early and late rice seeding, straw returning to field and the like. According to the method, an appropriate amount of straw is mechanically smashed and returned to the field to be utilized on the spot, base fertilizer containing a microorganism degrading bacterium agent is prepared to increase the composting speed of the straw, and therefore influences on next-stubble crops are avoided; nutrients are released according to season differences by combining different water and fertilizer conditions, and therefore the nutrients can effectively fertilize and improve soil or be absorbed and utilized by the crops.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a high-yield planting method for double-cropping rice. Background technique [0002] Double-cropping rice is a rice farming system in which two crops of rice are planted and harvested in one year in the same paddy field. The growth period of double-cropping rice is short and the effective tillering period is short. Therefore, it is necessary to ensure high yield and high quality. There is a certain demand for nutrition. With the improvement of agricultural intensification, the amount of chemical fertilizers applied to farmland continues to increase, and the amount of organic fertilizers decreases rapidly. Long-term large-scale application of chemical fertilizers leads to soil compaction, deterioration of aggregate structure, decline in fertility, and deterioration of physical and chemical properties. At present, the reasonable utilization rate of straw resources in my coun...
