Using mulching membranes for winter celery, compared with no mulching, the output of celery is increased by more than 30%. The petiole is soft and tender, and the quality has been obviously improved. Generally, it can be mentioned in the morning for 7-10 days. The price is good, and the operation is simple. low. Celery hi cool and weak light. After the film is covered, the light is weakened, which is beneficial to the growth of celery. Not only is the virus disease light, but also it grows young; celery is relatively hardy, but due to the low temperature during the winter season, the growth is slow or basically stops growing, and sometimes it also suffers from freezing injury, resulting in bad rot. handle. After the floating, the temperature of the soil and the temperature in the field are increased to a certain extent, so that it can resist freezing injury and promote the growth of celery. Celery growth density, but also easy to cover the floating film. Floating membrane coverage includes: 1, mulching With ordinary mulch, such as the film used for early rice breeding, the shed film removed from the shed can be used. The film must be clean so as not to affect the light transmission performance. Placing the mulch on the plants, the membrane edge is flush with the rim, ie, the top of the rim is not covered, exposing around, which is conducive to automatic temperature regulation and prevents the membrane from overheating and burning seedlings. The four corners of the film are fastened with strong ropes, and the other end is respectively tied with stones or red bricks to prevent the wind from blowing the film away. By adjusting the length of the rope, the membrane surface is slightly shaped like a turtle to facilitate drainage. If water or snow collects on the membrane, remove it in time. Under normal circumstances does not remove the film. If you need to top-dressing, you can open the film, drench fertilizer solution. After top-dressing, the celery plants are dried on the water and evaporated to prevent excessive temperature in the field. With the growth of celery, the membrane follows the float, and attention should be paid to adjusting the length of the rope or the position of the pressing brick, and it is generally necessary to remove the membrane in mid-February. 2, floating film cover The floating membrane is a special plastic film directly covered on the concentrated ground of vegetables. The thickness is 0.02 mm and the width is 1.5 to 2.0 meters. A large number of small holes are evenly distributed on the membrane to naturally adjust the water, gas and heat inside and outside the membrane to make the membrane. The internal temperature is not too high, the temperature will not be too large. This film can prevent low temperature, frost, but also can prevent high temperature burning seedlings and diseases caused by excessive temperature. The membrane can be used on celery, the floating membrane is naturally placed on cultivated leeks, and the membrane hangs down in the gingival sulcus. It can be compacted around the earth. Its management method is the same with the membrane floating cover. 3, floating net coverage Optional SZW?12, SZW?4 silver gray network coverage. This kind of net has better light transmission, but it can also prevent maggots and virus diseases, and it can also prevent frost. Coverage: December to February. The net cover was placed on the celery plant and compacted with soil on all four sides. As the net floats, adjust the position of the pressure block.
