About 90% of Putian, Nanzhao County, Henan Province, implements dry rice seedlings. However, there are different degrees of dead seedlings each year. The following methods are proposed to prevent or reduce the dead seedlings of dry seedlings. Improve the quality of seedbeds and prevent them from killing them. First of all, we must adhere to the principles of fertilizer, looseness and thickness in Putian, and choose fertile dry land for seedbeds. Secondly, improve the quality of fertilization, fertilize early in the spring, use organic fertilizer as the main fertilizer, apply the seedbed in advance, apply compound fertilizer 30 days before sowing, and use more than 15 cm depth of tillage to fully mix the soil fertilizer. . After fertilizing the seedlings sowing until the 5 leaves basically do not have to apply topdressing, 5 leaves after the lack of fertilizer symptoms can be combined with a small amount of irrigation to the fertilizer. Such a paddy field can improve the quality of seedbeds and also prevent the occurrence of fertilizer damage, which is conducive to making the seedlings neat and consistent and improve their resilience. Remove the film timely to prevent the dead and dead plants. After 5-7 days of sowing, the first complete leaf is uncovered when it is unfolded, which is conducive to cultivating strong seedlings and strengthening the resistance of seedlings, and at the same time, reducing or preventing the death of dead and dead seedlings. The film removal time should be determined according to the weather. On sunny days, the film must be removed in the early evening. After uncovering the film, it must be poured in a timely manner. It is best to remove water from the edge of the film. The cloudy film can be removed before 10:00 in the morning. Effectively prevent the occurrence of bruising. Shade and cool, prevent burning seedlings. In the spring, the weather is fickle and the temperature changes are relatively large. Attention should be paid to the weather forecast. When the average daily temperature reaches 20°C or less and the film removal time is not reached, straw must be stamped on the film to stabilize the film temperature at 35°C. In the following, high temperature is prevented from sprouting. Prevent pests and diseases. It is mainly used to control subterranean insects and the emergence of early seedling blight. In the past, there were seedling rooting phenomenon in Putian. Before sowing, it used 1000 times of phoxim EC and about 250 kg of uniform spraying. After the film was exposed to a large temperature difference in temperature, spraying the enemy with 2000 times liquid in advance could effectively prevent the emergence of blight.
