Second, there are too many effective spikes
The third is improper fertilizer and water management, partial application of early nitrogen fertilizer
According to the survey in 2010, more than 70% of the lodging fields use more than 270kg / h㎡ of pure nitrogen as base tillering fertilizer. Due to excessive nitrogen application in the early stage, rice grows vigorously, is shaded, and the population is large, which increases the risk of lodging in the later stage
In addition, due to mechanical damage, the exchange of nutrients in plants is blocked, which further strengthens the premature senescence of roots and leaves, affects photosynthesis, and reduces photosynthetic substances, resulting in incomplete filling, decreased thousand-grain weight, increased grains, and decreased seed setting rate.
Second, the quality of rice has declined
The ears of rice have been in a high-humidity environment for a long time, and some rice grains have mildewed and germinated, the gloss of the rice is poor, and the quality and yield of the rice are reduced.

Embodiment 1
[0020] A method for cultivating rice resistant to lodging, comprising the following steps:
[0021] 1) Select lodging-resistant varieties: In terms of variety selection, varieties with short internodes, moderate plant height, thick stems, upright leaves, short leaves and well-developed root systems should be selected;
[0022] 2) Extended row transplanting, reasonable and sparse planting, adopt wide row narrow planting method, row spacing is 13cm×23cm, planting density is 18,000 holes / 667㎡; basic stem seedlings should be controlled at 72,000 seedlings / 667㎡. Adopt the planting method of wide rows and narrow plants, expand the distance between transplanting rows and reduce the number of basic seedlings, improve the ventilation and light transmission between groups in the middle and late stages, make the stem and leaf tissues old and healthy, ensure the robustness of the plants, slow down the occurrence of pests and diseases, and improve the lodging resistance. The distance bet...
Embodiment 2
[0028] It is basically the same as Example 1, the difference is that step 2) transplanting in extended rows, reasonable and sparse planting, adopts the planting method of wide rows and narrow plants, the row-to-plant spacing is 13cm×23cm, and the number of seedlings in the planting density is 18,000 holes / 667 ㎡, Step 4) The ratio of basal tiller fertilizer to ear grain fertilizer is 5.5:4.5.
experiment example
[0030] The paddy rice that adopts above-mentioned embodiment 1, 2 plantation, effective panicle increases 10.2%, total grain increases 10.2%, solid grain increases 10.5%, seed setting rate increases 10.3%, thousand grain weight increases 10.1%, theoretical yield increases 10.9%, actual yield increases 10.9% %, the rice is of high quality and tastes good.

Abstract
The invention discloses a method for cultivating paddy rice in a lodging resistance way, comprising the following steps of (1) selecting a lodging resistance variety; (2) implementing row-expanding transplant and rational sparse planting; (3) rationally irrigating to keep the alternate dry or wet status of a paddy field; (4) rationally applying fertilizer to optimize nitrogen fertilizer management; (5) enhancing control on plant diseases and insect pests, i.e. enhancing control on rice planthopper, banded sclerotial blight, rice joint blast and chilo suppressalis; (6) after the occurrence of lodging, timely adopting remedial measures, i.e. timely ditching for water discharge, implementing the foliage top dressing of foliar fertilizer, and bunching and strengthening after lodging. By the adoption of the method for cultivating the paddy rice in the lodging resistance way, as the resistance against external environmental conditions is enhanced, the lodging resistance capability of the paddy rice can be improved; after suffering natural hazards such as typhoon and rainstorm, the paddy rice grows well; therefore, available spikes are increased by 10.2%, total grains are increased by 10.2%, and filled grains are increased by 10.5%; the maturing rate is increased by 10.3%, the thousand grain weight is increased by 10.1%, the theoretical yield is increased by 10.9% and the actual yield is increased by 10.9%; in addition, the rice grains are excellent in quality, the cooked rice is tasted good, and the economic benefits are obvious.
Description
technical field [0001] The invention belongs to the technical field of rice cultivation, in particular to a cultivation method for rice lodging resistance. Background technique [0002] Rice is the largest food crop in Jurong City, with an annual planting area of 31,100 hm 2 Left and right, due to the popularization and application of new varieties and new technologies, its output and benefits have been greatly improved. However, due to frequent natural disasters in recent years, a certain area of lodging occurs every year, which affects the improvement of the overall level of rice production and benefits throughout the year. The thousand-grain weight of rice is only 19.95g, and the seed setting rate is 75.8%, which is 6.45% lower than that of normal fields. g, 17.7%, germination on the rice spikes at the bottom of some fields. The lodging harvest time is 7-10 days earlier than normal fields, which further increases the yield loss and affects the quality of rice. [0...
