Embodiment Construction

[0028] The method for cultivating paddy rice of the present invention operates according to the following technical procedures:

[0029] 1), dry seedling raising

[0030] (1) Variety selection: select mid-to-late maturing varieties with high quality, high yield, strong stress resistance, and good comprehensive traits;

[0031] (2) Growth period limit: sow on May 5-10, transplant around June 20, seedling order is 40-45 days, mature before October 10, and the whole growth period is 150-155 days;

[0032] (3) Seedling field selection: The seedling field should choose dry soil with flat terrain and good drainage, preferably a vegetable garden. The seedbed soil should be loose and fertile, with good water and air permeability, high organic matter content, strong water and fertilizer supply capacity, and weakly acidic PH4 .5~5.5;

[0033] (4) Fine soil preparation: winter plowing before winter plowing or 10-15 days before sowing, plowing and harrowing, the finer the soil preparati...

Abstract

The invention discloses a rice cropping method. Based on thin seeding, dried breeding and seedling strengthening and spaced planting on small mound, the method changes the traditional nitrogen application proportion that base fertilizer:tillering fertilizer:earing fertilizer:granular fertilizer is equal to 50 percent:15 percent:35 percent:0 percent, to 40 percent:15 percent:35 percent:10 percent. The method also properly reduces previous nitrogen application amount, increases nitrogen application amount in middle and late stages, reduces ineffective tillering and tries for large ears and large amount of grains; the method changes the traditional method that K fertilizer is only used as a base fertilizer rather than additional fertilizer to adopt the K fertilizer as both the base fertilizer and the additional fertilizer so as to improve the disease resistance and fall resistance of rice as well as maturing rate, and increase dry grain weight. The rice cropping method is characterized by good quality, high yield, high efficiency, low consumption and the like.

Description

technical field [0001] The invention belongs to the technical field of rice cultivation, and relates to a method for cultivating rice. Background technique [0002] Traditional rice cultivation methods include "V"-shaped cultivation, reverse "V"-shaped cultivation, three-dry cultivation and dry-raised sparse planting and other cultivation techniques. In terms of fertilization and promotion and control, the traditional cultivation of N fertilizer is "single saddle". Cultivation method, K fertilizer is only used as base fertilizer and not as top dressing. The cultivation methods of the prior art have technical problems such as poor quality, low yield, low efficiency and high consumption. Contents of the invention [0003] The purpose of the present invention is to solve the technical problems such as poor quality, low yield, low efficiency and high consumption in the cultivation method of the prior art, and provide a method for cultivating rice to overcome the deficiencies ...
