Embodiment

[0026] The embodiment of the present invention provides a method for cultivating rice. The method includes making seedlings to be transplanted, selecting full-grained rice seeds for dry seedling cultivation, and obtaining the seedlings to be transplanted when the seedlings reach 4 to 5 leaves; in practical application In the seedlings, 200ppm paclobutrazol was sprayed from the stage of one leaf and one heart to the stage of two leaves.

[0027] Plowing and fertilizing management, plowing the rice fields to be planted and applying soil and miscellaneous fertilizers according to the standard of applying more than 6000kg of soil and miscellaneous fertilizers per mu; and applying compound fertilizer base fertilizer one day before transplanting, and the proportion of each nutrient in the compound fertilizer base fertilizer for N:P 2 o 5 :K 2 O=2:1:2, the total nutrient content is 40%;

[0028] transplanting, such as figure 1 As shown, the obtained seedlings to be transplanted a...

Abstract

The invention discloses a rice cultivation method. The method includes the steps that seedlings to be transplanted are manufactured; tillage and fertilizer application management are conducted; transplanting and planting are conducted; field fertilizer application management is conducted. According to the method, liquid silicon potassium is sprayed to leaf surfaces in the inverse fourth leaf stage and in the inverse second leaf stage respectively according to the amount of 200 mL/mu; when the number of stem tillers reaches 85% of the predicted ear number one leaf age before the critical period of effective tillers, drainage and water treatment start, jointing is conducted till rice is ripe, then moistening irrigation is conducted, and alternation of wetting and drying is conducted. According to the cultivation method, the yield of super rice can be increased, ventilation and light-pervious performance on the lower middle portions in the later stage of breeding can be improved, rice blast of super rice is reduced, jointing is conducted till rice is ripe, then moistening irrigation is conducted, alternation of wetting and drying is conducted, and the aims of high yield of super rice, sheath blight prevention and rice blast prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a rice cultivation method resistant to sheath blight and rice blast. Background technique [0002] Super rice varieties have the advantage of high yield potential. In 2014, the yield of super rice reached 1026.7kg / mu, but the super high-yield cultivation technology matching super rice is relatively backward. The main goal of super high-yield cultivation technology of super rice is: It is a super-high-yield rice technology that has greatly improved the yield of the variety and takes into account both quality and resistance. [0003] Sheath blight is a fungal disease caused by Rhizoctonia solani. It is one of the most common major diseases of rice. Generally, the early rice is heavier than the late rice, which often causes the grains to be not full, the empty shell rate increases, and the serious ones can cause the plants to fall and die. Rice blast is one of the important ...
