In the south of China, rice planting needs to be planted first, and then rice transplanting is carried out. Therefore, we need to prepare rice transplanting in advance, and learn the field management techniques of planting rice with less money. The following is a detailed field management method.
At present, most of the seedlings of rice seedlings have entered the 2.5-leaf stage, and rice farmers who have been tested have begun to enter. After more than ten days, they will enter the transplanting stage. At this time, rice farmers should prepare for transplanting (the leaf age is 3.1 in this period). ~3.5 leaves, take 3 to 4 days). Seedling management work needs to pay attention to the following aspects:
I. Do a good job in the classification management of seedlings of different leaf ages and different growth conditions, to achieve standard control of small seedlings, strict control of large seedlings, and to increase the amount of ventilation in the greenhouses with early sowing and early seedlings, and to make younger seedlings with late sowing date. It is good to prevent early ear and blight (green wilt) work. Each shed area should be managed by a special person to ensure timely ventilation and refining, strict temperature control and humidity control, to ensure that the seedlings are not long, and that they are not inserted when they are inserted.
Second: do a good job in controlling water and seedlings. When the seedlings enter the 3.1-3.5 leaf stage, they should control the water seedlings. When the seedlings are not wilting, they will be in a state of hunger and thirst, so as to facilitate the rooting, good returning, and tillering after transplanting. early.
Three: 3 to 4 days before transplanting, it is necessary to control the roots of water and seedlings, and do a good job of “three belts†before transplanting (in combination with the daily transplanting area, the “three belts†of seedlings are implemented in batches.)
The "three belts" of the seedbed are to give the seedbed "with fertilizer", "with medicine" and "with bacteria" before the seedling transplanting. With a small investment, it can produce a good effect of fattening and insect control.
With fertilizer: one day before transplanting, 120-150 grams of diammonium per square meter of seedbed, after pouring a little water, how many seedlings can be inserted the next day, how many seedlings will be applied to the first day. The seedling plate of diammonium should be uncovered the next morning, and the seedlings should not be rolled up the night before to prevent burning. The seedbed with diammonium can increase the utilization rate of diammonium, improve the disease resistance of rice seedlings, promote rooting and promote early tillering.
With medicine: prevention of leaf miners and negative mud worms; especially the seedlings, seedlings, weak seedlings, easy to occur after transplanting! It is to prevent the occurrence of Honda leaf miner to a certain extent by using 18 grams of "pyridone" or 30 ppm of imidacloprid water per 360 m2 greenhouse before 2-3 days before transplanting. Save labor and save money!
Carrying bacteria: Preventing cold damage and promoting return to green. Rapidly repair damaged roots of transplanted plants, increase the number of roots, shorten the returning stage, and enter the tillers early. It can also resist the cold damage during spring transplanting, improve the self-resistance of seedlings, balance growth, rebuild and activate seedling autoimmunity. system. A certain amount of high quality biological fungicide can be applied while diammonium is applied. The rice seedlings have beneficial bacteria. After transplanting, they can accelerate the speed of greening, promote tillering, and improve the utilization rate of fertilizer in Honda.
When transplanting rice, we must do field management in advance to help the growth of rice transplanted seedlings, and to prevent pests and diseases from spending less.
