How to transplant rice? I'm talking about artificial transplantation.

1. What are the quality requirements for rice transplanting? How to improve the quality of transplanting rice?

Rice transplanting is a special operation in rice field production, which is highly standardized. Main requirements: the ground is as flat as a mirror, the ridge is as straight as a line, the canal system is matched, the hole rows are consistent, the density is reasonable, and the degree of seedling protection is high. When working in the water layer, there must be strong seedlings, moderate mud rot and loose paste, which is conducive to seedling transplanting and rooting. These five conditions are the basis to ensure the quality of transplanting, and the quality of transplanting was the key at that time: according to the requirements of variety, yield and fertilization level, determine the reasonable planting density, transplanting form and number of seedlings per hole; The seedlings should be rooted underground, and the roots should not be damaged during transportation and transplantation, so that the shallow transplantation does not drift the seedlings, and the transplanting depth should be controlled between 2 and 3 cm, so as to resolutely overcome the deep transplantation and prevent the seedlings from inserting into the nest. After transplanting, it is necessary to supplement it in time, and replanting seedlings is the guarantee to adhere to the quality of transplanting. It is required to complete this operation within 3 days after transplanting, and pay attention to sealing the nest after replanting to prevent the seedlings from drifting again.

2. What is the general density of ultrathin cultivation?

3. What is the general density of seedling throwing cultivation?
