rice seedling cultivation farming crops film polypropylene non woven fabric agricultural mulch
Rice non-woven fabric is a new kind of high efficiency polystyrene fiber hot pressing covering material. It has the characteristics of heat preservation, air permeability, anti-condensation, corrosion resistance and durability. For many years, rice seedling field has been using plastic film cover seedling, although this method has good thermal insulation performance, but seedlings are easy to grow, the occurrence of bacterial blight and bacterial blight, and even high temperature burning seedling phenomenon, every day to give seedlings ventilation, trouble, seedling beds need a lot of water supplement. Non-woven rice seedling technology is another innovation of rice seedling technology, non-woven rice seedling instead of plastic film seedling. Non-woven mulch can provide relatively stable light, temperature, air and other environmental conditions for the growth of early rice seedlings, and promote the better development of seedlings, thus increasing the yield per unit area of rice. Two years of testing showed that non-woven mulching increased yield by about 2.5%.
Second, advantages and disadvantages
1. Special non-woven fabric with microporous natural ventilation, the highest temperature in the film is 9~12℃ lower than the plastic film cover, the lowest temperature is only 1~2℃ lower than the plastic film, temperature stability, avoid the phenomenon of high temperature burning seedlings in the plastic film cover.
2, rice seedlings with special non-woven cloth cover, humidity change, without artificial ventilation seedlings, can obviously save labor, reduce labor intensity.
3, non-woven permeable, rainwater through non-woven into the seedbed soil, can use natural rainfall and agricultural film is impossible, so as to reduce the number of watering, save water labor.
4, non-woven cover seedlings short and strong, neat, tiller, straight leaves, leaves darker color.
Reduce environmental pollution. The service life of non-woven fabric for rice seedling is 3 years, which is equivalent to agricultural film. However, because it is made by hot pressing of a polypropylene substrate spinning machine, it is more easily degraded than agricultural film under the physical action of sunlight. In addition, it has air permeability and permeability. Even if some debris does enter the soil, it does not have the same negative effects as agricultural mulch that hinder soil water and nutrient transfer, so it is much less polluting than plastic mulch.
6. Increase rice yield per unit area. Because the non-woven dry seedling is strong, it is beneficial to increase the yield of rice, generally increasing by 2~5%.
7. The transmittance of non-woven cover decreases, and the transmittance of plastic film cover and non-woven cover respectively accounts for 76% and 63% of atmospheric light, with little difference between the two. However, under seedling conditions, it accounts for only 61% and 49% of atmospheric light, respectively. This may be because the soil moisture of water seedlings is significantly higher than that of dry seedlings, resulting in more dew, lower permeability and lower illumination. Non-woven mulch is suitable for dry seedlings.
