A kind of cultivation method of perennial rice

Abstract

The invention discloses a cultivation method for perennial rice. The perennial rice variety with strong perenniality and stable yield is selected for dry seedling cultivation; transplanted into the paddy field, and the paddy field is managed with fertilization and controlled water drying; Water-dried field, the field is not flooded and the relative soil humidity is 35% to 55%. Apply root-preserving and germination-promoting fertilizer within 20 to 25 days after earing; when harvesting perennial rice in the one-season rice area, keep rice piles of 15cm to 25cm for overwintering ; In the double-cropping rice area, when the early rice harvests the perennial rice, keep the rice pile 2cm to 5cm for late rice production, and when the late rice harvests the perennial rice, keep the rice pile 15cm to 25cm for overwintering; Keep 2cm to 5cm of rice piles; before the perennial rice enters the overwintering period, sow intercropping crops around the rice piles of perennial rice. The method increases the yield of perennial rice through fertilization while taking into account the quality of the rice. The reserved rice piles provide sufficient nutrition for winter axillary bud dormancy, and intercropping with other crops during the overwintering period improves the survival rate of the rice piles and increases planting benefits.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and relates to a technical method for the survival rate of perennial rice piles and a high yield, in particular to a cultivation method for perennial rice. Background technique [0002] Perennial rice is a rice variety that can be harvested continuously for many years (multiple seasons) once planted. Perennial rice utilizes the axillary buds of its underground stems (below the soil surface) after harvesting to survive the winter safely and re-grow, and restore normal rice production capacity in the next year (season), and then realize the production of perennial rice. Perennial rice is a new rice product. The measured yield of single-cropping rice is 500 kg / mu-600 kg / mu, and the measured yield of double-cropping rice is 1,000 kg / mu-12,000 kg / mu (early rice + late rice). From the second production season From the beginning, it is no longer necessary to purchase seeds, seedlings, tra...

AI Technical Summary

Problems solved by technology

[0008] The above-mentioned technical problems have hindered the popularization and application of perennial rice to a certain extent. In order to solve the above problems, after the research and development of the inventor's team, an effective solution to the low yield of perennial rice and the low survival rate of rice piles between early and late rice has been invented. 1. A cultivation and management method with low survival rate of overwintering rice piles. This method improves the survival rate of early and late rice piles and overwintering survival rate of perennial rice, and solves the problems that perennial rice seedlings are not uniform, can not be fertilized normally at the same time, and can be normally controlled by diseases and insect pests. , greatly improving the yield and quality of perennial rice as a whole
