The latest course on Seedling raising and transplanting techniques and methods of Rice

Rice is a very important food in our life, it is cultivated almost all over the country, and it is an indispensable crop. The main planting method of rice is to raise seedlings and transplant. First of all, it is necessary to do a good job of raising seedlings in order to ensure the seed setting rate and increase the yield of rice. So what exactly should be done when growing rice? The following editor has brought you the techniques of raising and transplanting rice seedlings. Let's have a look!

1. Seedbed management

Before raising seedlings, we should first apply sufficient fertilizer in the seedling bed to ensure that there is fertilizer in the whole tillage layer as far as possible, and the base fertilizer is mainly farm manure, compound fertilizer and micro-fertilizer. Then do a good job in disinfecting the seedbed, eliminate the germs in the soil, and take preventive measures for various diseases such as blight and cotton rot. Spray disinfectant comprehensively and evenly, and then do a good job of seed selection. It is mainly hybrid rice with high yield, high tillering rate and strong disease resistance. Control the amount of seeds according to the planting area, do a good job of soaking seeds and accelerating germination, put the exposed seeds at room temperature and cool for about 12 hours.

2. Sowing seeds at the right time

The time of sowing and raising seedlings should be about 4 weeks before transplanting, and the seeds should be pressed into the soil to increase the contact area between seeds and soil. Sow and then cover the fine soil. After sowing the seedbed to do a good job of heat preservation and moisturizing work, it is best to carry out a shed, every 60cm or so to insert a bow bar, the distance is controlled at about 35 cm. Then fix it with soil and easily build the greenhouse. The temperature in the shed should be controlled at about 31 degrees, not too high or too low, in a suitable environment, can effectively improve the growth ability of seedlings.

3. Timely transplanting

When transplanting, we should first plan the planting density in the field, and then raise the seedlings in the position of about two centimeters of soil to prevent seedling injury. Transplanting with soil can not only ensure fertility, but also prevent floating seedlings. When planting, the wide row and narrow plants are the main ones, and the ridges are inserted smoothly. The transplanting quantity should be controlled according to the soil fertility. When transplanting rice seedlings, we should also pay attention to control the depth, the depth should not exceed 2cm. Then do a good job of management, and the seedlings basically do not return to green after transplanting, so the time of maturity can be about 1-2 weeks in advance.

4. Post-planting management

Reasonable management should be carried out after seedling transplanting, and proper topdressing and tillering fertilizer should be applied after planting for about a week. Improve soil fertility, ensure adequate nutrition for seedling growth, promote seedling tillering, and then make rational use of herbicides to do a good job of weeding to prevent weeds from grabbing the growth of seedlings. Then according to the growth of rice, reasonable topdressing of panicle fertilizer, grain fertilizer and other fertilizers. To meet the nutritional needs of rice growth, moisture should also be reasonably adjusted according to the growth of rice. The suitable growth environment is very helpful to the growth of rice.

The above is a brief introduction of rice seedling transplanting technology. The work of raising rice seedlings is very important, and we should also do a good job in management. if it is not managed properly, it will have a great impact on the yield and quality, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
