How to do well rice transplanting? Management skills of Rice transplanting during transplanting period

In southern China, rice planting must first plant seedlings, and then carry out rice transplanting, so people must prepare for rice transplanting in advance and learn the cultivation techniques of planting rice with less money. The following are detailed cultivation techniques.

At the present stage, most of the leaf age of rice seedlings has reached 2.5 leaf stage, and rice farmers have just begun to try to transplant rice, and they will enter the transplanting period in more than ten days. At this time, rice farmers should prepare in advance before transplanting (the leaf age is 3.1-3.5 leaves, it takes 3-4 days). In seedling management, attention must be paid to the following aspects:

First, do a good job in the grouping management of seedlings with different leaf ages and different growth and development, ensure standardized control of seedlings and strict control of large seedlings, and increase natural ventilation in greenhouses with earlier sowing dates and older seedlings. Young seedlings with late sowing date are doing a good job in preventing early panicle and bacterial wilt (bacterial wilt). All shanty areas should be equipped with full-time personnel management methods to ensure immediate natural ventilation and seedling refining, strict temperature control and humidity control, ensure that the seedlings are not steep and long, and do not transplant over-aged seedlings.

Second: to do a good job of draining water and strengthening the root of squatting seedlings, when the seedlings enter the 3.1-3.5 leaf stage, it is necessary to drain water squatting seedlings and make them in an unbearable condition without withering, so as to facilitate good hair, quick return to green and early heading after transplanting.

Third: 3-4 days before transplanting, drain the water and strengthen the roots of squatting seedlings, and do a good job of "three belts" before transplanting (integrate the total area of transplanting seedlings every day, and implement the "three belts" of seedlings in batches. )

The "three belts" at the seedling stage means "carrying fertilizer", "medicine" and "a lot of bacteria" to the seedling stage before transplanting big trees. With very little capital investment, it can produce a very good practical effect of gaining weight and preventing moths.

With fertilizer: one day before transplanting, 150 grams of diammonium 120 per square meter should be applied at the seedling stage, and a little water should be poured after application. How many plates of seedlings can be planted the next day, and how many plates of seedlings should be given diammonium on the first day. The seedling tray of diammonium should be unveiled the next morning, and the seedlings should not be rolled up the night before to avoid burning the seedlings. Taking diammonium at seedling stage can increase the utilization rate of diammonium, improve the disease resistance of rice seedlings, promote root growth and promote early heading.

Take medicine: prevent leaf miners and negative mud insects; especially the steep growth of seedlings, diseased seedlings, weak seedlings, after transplanting is very easy to produce diseases and insect pests! That is to say, using 18 grams of "imidacloprid" or imidacloprid with 30 jin of water in every 360-inch greenhouse 2-3 days before transplanting can prevent the production of Guangzhou Honda leaf miner to a certain extent. Save time and make good use of it!

There are a lot of bacteria: prevent ultra-low temperature frost injury and promote green. Rapid repair of transplanting injury to the rhizome, increase the total number of roots, reduce the green period, advance to heading, both can resist the ultra-low temperature freezing injury in the spring transplanting period, improve the drought resistance of the seedling itself, balance the growth and development, and build and stimulate the seedling self-immune system software again. A certain amount of high-quality biological agent can be applied in addition to the application of diammonium. Rice seedlings with intestinal probiotics can accelerate the rate of turning green, promote heading and improve the utilization rate of organic fertilizer in Guangzhou Honda after transplanting.

When transplanting rice, we should do a good job in cultivation techniques in advance, which is beneficial to the growth and development of rice transplanting seedlings and prevent diseases and spend less money.
