Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for cultivating and planting lodging-resistant rice, which solves the problem that rice is prone to lodging during the growth process. After the rice is lodging, the stems and leaves overlap each other, and only a few leaves can be irradiated by sunlight. , seriously inhibit photosynthesis and the formation of photosynthetic products, flower pollination and grain filling cannot be smooth, and some rice varieties that are prone to lodging will seriously affect the rice yield.

Embodiment 1

[0031] Step 1: Basic work before rice cultivation: Use purified water to clean and sterilize all agricultural instruments involved in cultivation and planting, then wipe the cleaned instruments with a dry cotton towel, and then enter the standby state, and some machines are turned on to preheat ;

[0032] Step 2: Preparation of rice seeds and clay before cultivation: After selecting the rice seeds, soak the seeds for 40 hours, take them out, dry them, sterilize them, and select sticky mellow soil. Sieve to make nutritious soil, and prepare human and animal manure as biological fertilizer, and sieve after 30 days of composting;

[0033] Step 3: Rational seedling raising: Use special rice promoter and control agent to raise rice seedlings. The promoter and control agent are evenly mixed in the nutrient solution and added to the cultivation soil and fertilizer in time. The distance between them is 8cm;

[0034] Step 4: Optimized fertilizer and water management at the seedling s...

Abstract

The invention discloses a cultivation and planting method of lodging-resistant rice, which specifically comprises the following steps: step 1: basic work before rice cultivation, step 2: preparation of rice seeds and clay before cultivation, step 3: rational seedling cultivation, and step 4: The optimized fertilizer and water management at the emergence stage, step 5: the optimized water management at the emergence stage, the invention relates to the technical field of lodging-resistant rice. The cultivation and planting method of lodging-resistant rice, through the joint setting of step 1 and step 3, the staff can fully clean and disinfect the agricultural equipment, so that the rice can obtain a relatively stable seedling environment when raising seedlings, and avoid microorganisms from affecting the rice. For the damage of seedlings, use special accelerators to grow rice seedlings. Rice accelerators contain high-activity accelerators and large, medium, and trace elements to promote the development of roots, increase photosynthetic rate, increase effective tillers, increase the number of grains per spike, and increase carbon The nitrogen ratio promotes vegetative growth.

Description

technical field [0001] The invention relates to the technical field of lodging-resistant rice, in particular to a cultivation and planting method of lodging-resistant rice. Background technique [0002] Rice is a cereal crop belonging to the genus Oryza, and the representative species is rice. Rice lodging refers to the phenomenon that the upright growing crop is skewed in pieces due to natural factors such as wind, hail and heavy rain or the influence of external forces, or even the whole plant falls to the ground. Lodging can reduce the yield and quality of crops and make harvesting difficult. When crops such as wheat and rice are seriously lodged, the yield will be seriously affected, and even the harvest may be lost. Lodging mostly occurs after crop jointing and in the middle and late stages of crop growth. In the process of rice cultivation, different degrees of lodging often occur. There are two common types: one is the lodging of the base, and the other is the lodgi...
