Scientific cultivation method of Taoyou Xiangzhan (indica-variety three-line hybrid medium late rice)

Abstract

The invention discloses a scientific cultivation method of Taoyou Xiangzhan (indica-variety three-line hybrid medium late rice), and belongs to the field of rice cultivation. The scientific cultivation method of the Taoyou Xiangzhan comprises the following steps: S1, processing a rice seedling bed, namely selecting a rice seedling bed, and carrying out processing so as to achieve a regular bottomwidth of 2 m, a groove width of 0.5 m and a groove depth of 0.2 m; S2, carrying out sowing in good time, namely sparsely sowing raised seedlings, scattered-planting on June 17th to June 20th, transplanting with soil-removed big seedlings on June 21th to June 23th and machine transplanting on June 23th to June 25th; S3, processing a rice field, namely planting 10 kg of Chinese milk vetch in a ricefield in May, allowing the Chinese milk vetch to grow and mature in one month, carrying out mechanical plowing so as to have the mature Chinese milk vetch buried, and synchronously applying an organicfertilizer at a dosage of 170-210 kg / mu; S4, carrying out transplanting in good time, namely carrying out rational close planting, scattered-planting with long-age seedlings and transplanting with soil-removed big seedlings controlled within 25 days and machine transplanting controlled within 20 days; S5, carrying out scientific fertilization, namely applying sufficient base fertilizer in line with the rule of heavy application of base fertilizer, early application of top dressing and late application of ear fertilizer as appropriate; S6, carrying out scientific water management, namely sunning the rice field in good time, and managing water in line with the rule of shallow planting in thin water, living stump in deep water and tillering in shallow water; and S7, preventing and treating diseases, insects and pests. The scientific cultivation method of the Taoyou Xiangzhan is capable of ensuring relatively low morbidity, high cultivation efficiency and vigorous growth.

Description

technical field [0001] The invention relates to the field of rice planting, more specifically, to a scientific planting method of Tao Youxiangzhan. Background technique [0002] Tao Youxiangzhan is an indica-type three-line hybrid medium-maturing late rice, with a total growth period of 113.4 days and a plant height of 100.8 cm. Leaf sheaths and lemma tips are purplish red, and fade well in the later stage. The effective panicle per mu is 220,000 panicles, the total number of grains per panicle is 119.5, the seed setting rate is 79.7%, and the thousand-grain weight is 28.8 grams. [0003] However, the existing planting method of Taoyouxiangzhan is unscientific, which leads to a high disease incidence rate of the variety rice, and the growth is not vigorous, which greatly affects the economic benefits. Contents of the invention [0004] 1. Technical problems to be solved [0005] Aiming at the problems existing in the prior art, the object of the present invention is to p...
