Embodiment 1

[0021] One mu of low- and medium-yield winter idle field, good water source, transplanting seedlings within 20-40 days of age, transplanting density of 7 × 7 inches, and the number of transplanted grains is 1-2 grain seedlings; one-time planting and whole field Fertilization rate: apply 10kg ammonium bicarbonate; apply 50kg superphosphate or calcium magnesium phosphate fertilizer; apply 15kg potassium sulfate, and apply the above fertilizers at one time when the seedlings are planted and the whole field, that is, no fertilization will be applied in the future. The water level of the paddy field should not exceed 5cm. When the middle rice is tillered, the field should be dried several times in a timely manner, and a large dose of river sand should be mixed with the herbal medicine.

Embodiment 2

[0023] One mu of low-yield winter idle field, good water source, transplanting within 20-40 days of seedling age, transplanting density of 8 × 8 inches, and the number of transplanted grains is 1-2 grain seedlings; once when planting the whole field Fertilization rate: Apply 15kg ammonium bicarbonate; apply 50kg superphosphate or calcium magnesium phosphate fertilizer; apply 5kg potassium chloride plus 10kg potassium sulfate, and apply the above fertilizers at one time at the time of planting and whole field, that is, no fertilization will be applied in the future. . The water level of the paddy field should not exceed 8cm. When the middle rice is tillered, the field should be dried several times in a timely manner, and a large dose of river sand should be mixed with the herbal medicine.

Embodiment 3

[0025] One mu of self-producing green manure field in low-to-mid-yield winter, good water source, lush green manure growth, and return all green manure to the field, transplant the seedlings within 20-40 days of age, the transplanting density is 7.5×7.5 inches, and the number of transplanted grains is 1-2 Grain seedlings; one-time fertilization amount when planting and whole field: apply 3kg ammonium bicarbonate; apply 50kg superphosphate or calcium magnesium phosphate fertilizer; apply 15kg potassium sulfate; apply the above fertilizers at one time when planting and whole field Finished, that is, do not fertilize in the future. The water level of the paddy field should not exceed 5cm. When the middle rice is tillered, the field should be dried several times in a timely manner, and a large dose of river sand should be mixed with the herbal medicine.

Abstract

The invention provides an environmentally friendly yield-increasing cultivation method of hybrid middle-season rice, comprising the following steps of sowing and culturing seedling, transplanting, fertilizing and managing paddy field. By scientifically fertilizing, reasonably irrigating and reasonabe thick planting, the method reduces and precludes a third tillering of the middle-season rice, andimproves the air permeability and the light transmission of rice paddy, thereby improving resistance to diseases and insects without or with a little pesticide and realizing the environmentally friendly yield increasing of the middle-season rice,. The method also can shorten the vegetative period of the middle-season rice and extend the reproductive stage of the middle-season rice. Compared with the traditional cultivating method, the method features more regular and symmetric millet sprays, fuller and more regular grain, higher milled rice rate and better rice quality, and is a real environmentally friendly yield-increasing cultivation method of hybrid middle-season rice.

Description

technical field [0001] The invention relates to a cultivation method of hybrid medium rice, in particular to an environment-friendly and yield-increasing cultivation method of hybrid medium rice. Background technique [0002] Medium and low-yield fields refer to fields with poor sunlight, poor air permeability, poor soil fertility, poor soil quality, cold soaking, slightly higher altitude, slightly lower temperature, and rampant pests and diseases. ,low quality. Improving the yield and quality of rice in low- and medium-yielding fields is an urgent problem to be solved by many scientific and technological workers and the general public. In order to achieve the purpose of increasing production and income, the method commonly used by the people at present is to use a large amount of fertilizers and pesticides, and the most used fertilizer is urea. The disadvantage of this method is that it will not only increase the production cost of farmers, but also the rice contains pest...
