Problems solved by technology

The disadvantage of this method is that it will not only increase the production cost of the farmers, but also the rice contains pesticides, which are very harmful to people's health

Embodiment 1

[0021] Medium and low-yielding winter fallow field of one mu, good water source, transplanting within 20-40 days of seedling age, transplanting density of 7 x 7 inches, transplanting grain number of 1-2 grain seedlings; one-time when planting seedlings and whole field Fertilization amount: apply 10kg of ammonium bicarbonate; apply 50kg of calcium superphosphate or calcium magnesium phosphate fertilizer; apply 15kg of potassium sulfate, and apply the above fertilizers at one time when planting seedlings and whole fields, that is, no more fertilization in the future. The water level in the paddy field should not exceed 5cm, and the field should be sunned several times at the right time when the middle rice is tillering, and a large dose of river sand should be mixed with the herbs.

Embodiment 2

[0023] Medium and low-yielding winter fallow field of one mu, good water source, transplanting within 20-40 days of seedling age, transplanting density of 8 x 8 inches, transplanting grain number of 1-2 grain seedlings; once when planting seedlings and whole field The amount of fertilization: apply 15kg of ammonium bicarbonate; apply 50kg of superphosphate or calcium magnesium phosphate fertilizer; apply 5kg of potassium chloride and 10kg of potassium sulfate, and apply the above fertilizers at one time when planting seedlings and whole fields, that is, no more fertilization in the future . The water level in the paddy field should not exceed 8cm, and the field should be sun-dried several times in a timely manner when the middle-aged rice is tillering, and a large dose of river sand should be mixed with the herbs.

Embodiment 3

[0025] One mu of self-growing green manure field with medium and low yield in winter, good water source, lush green manure growth, and all the green manure will be returned to the field, transplanted within 20-40 days of seedling 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 seedlings and whole field: apply 3kg ammonium bicarbonate; apply 50kg superphosphate or calcium magnesium phosphate fertilizer; apply 15kg potassium sulfate; apply the above fertilizers once when planting seedlings and whole field After that, no fertilization will be done in the future. The water level in the paddy field should not exceed 5cm, and the field should be sunned several times at the right time when the middle rice is tillering, and a large dose of river sand should be mixed with the herbs.

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, and improves 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 mid-season rice, in particular to an environment-friendly and yield-increasing cultivation method of hybrid mid-season rice. Background technique [0002] Medium and low-yielding 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. This kind of field occupies a considerable proportion in my country, and the rice yield of this kind of field is low. ,low quality. Improving the paddy output and quality of low- and middle-yielding fields is a problem to be solved urgently by many scientific and technological workers and the common people. In order to achieve the purpose of increasing production and income, the method generally adopted by ordinary people is to use a large amount of fertilizers and pesticides, and the most widely used fertilizer is urea...
