What is the plant spacing and row spacing of machine transplanted rice seedlings, rice transplanter and manual transplanting yield will be different?

The suitable plant spacing for machine transplanted rice is usually 20cm, and the suitable row spacing is usually 30cm, which can be adjusted according to the actual situation. The standard of machine transplanting is to drive the rice transplanter without affecting the transplanted seedlings, and can be inserted normally in the mud and water, when transplanting seedlings, you need to keep the width of the rice transplanter around the field for 1 time, and then from the outside to the inside of the transplanting, and finally to the outside and all around the transplanting of seedlings.

First, what is the plant spacing and row spacing of the machine transplanted rice seedlings

1, the plant spacing of machine transplanted rice seedlings is generally about 20 cm, and the row spacing is generally about 30 cm, which can be adjusted according to the actual situation in the planting process.

2, mechanical transplanting standard for driving rice transplanter can not have an impact on the seedlings have been inserted, and need to be in the mud and water normal transplanting.

3, machine transplanted seedlings can do four sides neat, uniform seedlings, effectively reducing the rate of empty insertion. When transplanting seedlings, you need to retain the width of the rice transplanter to walk 1 time around the field, and then transplant seedlings from the outside to the inside, and finally to the outside and all around the transplanted seedlings.

4, after transplanting seedlings, if you want to make up seedlings, should adhere to? There are seedlings not to make up, lack of 2 to make up 1 hole, lack of 1 hole need not make up? The principle. If the field seedlings missing 1 hole, for the yield generally will not cause a greater impact, that is, do not need to make up too many seedlings.

Second, rice transplanter and artificial transplanting yield will have a difference

1, the use of rice transplanter transplanting and artificial transplanting yield difference, in general, the use of rice transplanter paddy yield is higher than artificial transplanting paddy.

2, manual transplanting, the number of holes per square meter can not be accurately controlled (the number of holes is generally less), and the number of seedlings per hole is not uniform, and the seedling rejuvenation speed is also slower, which reduces the number of spikes per square meter, so that the yield is affected.

3, the use of ordinary rice transplanter, the yield is generally 1.2% higher than the manual transplanting; if the use of high-speed rice transplanter, it is 2% higher than the ordinary rice transplanter yield.

4, manual transplanting and the use of ordinary rice transplanter is prone to serious root tearing, and high-speed rice transplanter transplanting principle is block cut seedlings, and sufficient water, can reduce the damage caused to seedlings, accelerate the speed of its greening, promote seedling tillering, and increase the rate of fruitfulness as well as the number of spikes.
