Rice seedling tray nursery technology method

Rice seedling tray seedling technology methods: land preparation, seed treatment, seedling, transplanting, disease control.

1, land preparation

Rice is suitable for growth in fertile soil. When using rice seedling trays to raise seedlings, you need to mix field soil and sand to make nutrient soil, and then apply rotted fertilizer on the nutrient soil to make it more fertile, and then put the nutrient soil into the seedling trays and sterilize it at high temperature to promote the healthy growth of rice.

2, seed treatment

When planting rice, choose full, intact seeds, and then soak them with carbendazim for a period of time to eliminate germs on the surface of the seeds to reduce the rate of infection. The rice grains are then left to dry in the sun, turning them over every three hours to allow them to germinate quickly.

3, seedling

When using rice seedling trays for seedling, you need to sprinkle the seeds inside the trays, and only two seeds can be sprinkled in each tray, then water the trays once, and then put the trays into a greenhouse, and control the temperature inside the greenhouse at around 25 degrees, in order to promote the vigorous growth of rice.

4, transplanting

When planting rice, the plants need to be inserted into the soil when they grow to 8 centimeters high. It can be transplanted manually or inserted by machine, pulling out weeds in the paddy field in time to avoid weeds and rice robbing nutrients, and regularly spraying insecticides on the rice to eliminate snails and other pests.

5, disease control

Ribbons are the main disease in the seedling stage. The main cause of the disease is low temperature and humidity, temperature difference, soil alkali, insufficient light, sowing too much seed, seedling thin and weak and many other factors, which seriously affects the quality of rice seedlings, and even affects the rice yield, so it must be taken as a comprehensive prevention and control measures, focusing on prevention.

In addition to paying attention to temperature and water management during the nursery period, fungicides and plant growth regulators are sprayed during the three-leaf period to prevent chlorosis and to promote root development and control growth.
