The characteristics of agricultural non-woven seedling raising

Rice seedlings are usually covered with agricultural film for thermal insulation, which has good thermal insulation performance, but the temperature of the seedbed rises rapidly, and the temperature difference between day and night is large, which requires frequent ventilation and hardening, which is time-consuming and labor-intensive.

Therefore, many areas have begun to explore the use of non-woven seedlings, which can effectively provide better light, temperature, humidity and other environmental conditions for the growth of seedlings.

The characteristics of rice seedlings using non-woven fabrics:

1.Both heat preservation and ventilation, the temperature of the seedling body changes gently, and the seedlings are strong, which is manifested in many roots and thick stems.

2.It saves labor and time, and the non-woven seedlings are laid flat to reduce the operation links such as watering and ventilation. Due to the permeability of the non-woven fabric itself, the temperature buffer is stable and the temperature in the bed is uniform.

3.The reduction of pests and diseases, especially the pests, can reduce the pollution of pesticides to the environment.

4.The use cost is low, the recycling is convenient, and the non-woven fabric can be used 2-3 times continuously, reducing the pollution of the agricultural film to the environment.

5. The non-woven seedlings have high seedling completion rate, short slow seedling period after transplanting into the field, high tiller rate and ear formation rate, which is conducive to high yield.

Precautions for using non-woven seedling raising:

1.When using non-woven seedlings in spring, due to the low temperature, mulch should be placed on the non-woven fabric or first covered with mulch and then a layer of non-woven fabric to keep warm. The mulch can be taken out when the green head of the seedlings reaches 1 leaf and 1 heart.

2.The non-woven fabric has good permeability. Pay attention to water replenishment. Generally, water once every 7-10 days after the valley falls, and then keep half-ditch water in the future, and the board surface should not be watered.

The coverage should not be too tight, otherwise the growth of the seedlings will be affected if the seedlings grow larger for more days.

3.On the one hand, non-woven can reduce the occurrence of diseases in the seedling stage, and on the other hand, hinder the harm of pests, but it cannot prevent the occurrence of pests and diseases. Pay attention to more observations in the field, and prevent and treat diseases in time.

4.Before transplanting, the cloth should be uncovered in time, or the seedlings should be uncovered in time at about 3 leaves, 1 center to 4 leaves, and topdressing should be applied once according to the leaf color of the seedlings after uncovering.
