How many days of rice growing cycle, with planting methods

For early-maturing varieties, the growth cycle is usually about 60-90 days, and for late-maturing varieties, the growth cycle is usually about 210-240 days. Rice has a high demand for nutrients, and rotted organic fertilizer can be applied during the seedling period to improve soil fertility, urea can be applied during the growth period to promote plant growth and maturity, and potassium dihydrogen phosphate can be sprayed during the spike period to promote seed development. When leaf blight occurs, drugs such as tricyclazole wettable powder can be used for prevention and control, and when rice stem borer occurs, drugs such as diquat emulsion can be used for prevention and control, and other pests and diseases can be medicated according to the corresponding symptoms.

First, how many days of rice growth cycle

1, rice growth cycle

The growth cycle of rice varies according to varieties, early varieties of sowing after 60-90 days or so can be ripe, late varieties of sowing after 210-240 days or so to mature.

2, the conditions of planting rice

(1) to provide nutrients

rice in the growth period of the nutrient demand, in order to improve soil fertility, can be in the seedling phase of the application of rotted organic fertilizer. To promote plant growth and maturity, urea can be applied during the growth period. In order to promote the development of seeds, can be sprayed with potassium dihydrogen phosphate in the tasseling period.

(2) Supplemental light

①Rice is suitable for growth in a light-rich environment, planting should be selected as a sunny field, so that the rice plant receives full sunlight and normal photosynthesis.

② In summer, when the light is too strong, it is necessary to fill the deep water layer in order to provide sufficient water for the rice plant to ensure the healthy growth of the plant.

(3) pest control

When leaf blight occurs, you can spray clean seedling emulsion, tricyclazole wettable powder and other drugs, by the rice stem borer, you can spray trichlorfon emulsion and other drugs, other pests and diseases can be based on the corresponding symptoms of the medication.

Second, rice planting methods

1, soak seeds to promote germination

(1) choose full and full, pest-free seeds as the object of planting, and then soak the seeds in carbendazim solution for 1-2 hours to kill the germs attached to the surface.

(2) After soaking, dry the seeds for a period of time, and turn them every 1-2 hours to speed up the germination of the seeds.

2, land preparation and fertilization

Deeply plough the soil for 30 cm, and then apply sufficient rotted organic fertilizer and cake fertilizer to increase the fertility of the soil and promote the vigorous growth of rice.

3, seedling transplanting

Sprinkle the seeds in the nutrient bowl with nutrient soil to speed up the emergence of seedlings, and transplant them into the paddy field when the height of the seedlings reaches 7-8 cm. You can wear a seedling divider on your thumb while transplanting to fix the spacing between the plants.

4, management methods

(1) After the emergence of weeds, manual pulling or chemical weed control can be used.

(2) During the season of high incidence of pests and diseases, drugs such as chlorothalonil and carbendazim can be sprayed. After rice enters the tillering stage, it needs to be fertilized 2-3 times.
