About 90% of Putian now practices dry rice seedlings. However, there are different degrees of dead seedlings occurring every year. The following methods can prevent or reduce dead seedlings. Improve the quality of seedbeds and prevent them from killing them. First, choose a fertile dry land for the seedbed. Second, early fertilization, mainly organic fertilizer, applied to the seedbed in advance, 30 days before sowing application of compound fertilizer, and many times the depth of cultivator should reach 15 cm or more, so that the soil is fully mixed and mix well. After fertilizing the seedlings sowing to the first five leaves before basically do not topdressing, five leaves after the fertilizer deficiency symptoms can be combined with a small amount of irrigation to the fertilizer, both to improve the seedbed quality, but also to prevent the occurrence of fertilizer damage, help to promote the seedlings neat and consistent, improve disaster resistance ability. Remove the film timely to prevent the dead and dead plants. 5-7 days after sowing, the first complete leaf is uncovered when unfolding, which is conducive to cultivating strong seedlings and strengthening the resistance of seedlings, and at the same time, it can also reduce or prevent the death of dead seedlings and standing dead seedlings. The film removal time should be determined according to the weather. On sunny days, the film must be removed before the evening. After uncovering the film, it must be poured in a timely manner. It is best to remove the film while uncovering the film. The film can be removed on the cloudy day before 10:00 am. Prevent the occurrence of bruising. Shade and cool, prevent burning seedlings. In spring, the weather is changeable. When the average daily temperature is above 20°C and the time for film removal is not available, straw must be stamped on the film to keep the film temperature below 35°C to prevent high temperature burning. Prevent pests and diseases. It is mainly used to control the underground pests and the early emergence of seedlings. In the past, there were seedling rooting phenomenon in Putian. Before the seeding, the phioniulic emulsion was uniformly sprayed with 1000 times liquid 250 kg. When the temperature difference after uncovering the film is large, the enemy should be sprayed 2000 times ahead of time to effectively prevent the occurrence of blight.
