早稻收割前后,抓好稻底田菁的管理工作,这是获得田菁高产的重要一环。针对田菁后期生长的特点,在管理上应注意下面几个方面: 一、肥水管理。这时,由菁植株已较高大、枝叶繁茂、内部海绵组织增长很快,故需水需肥特别多,因此要灌深水。可结合夏耕,在田菁行间犁沟囤水;早稻收割后,每亩施过磷酸钙10至20斤,以加速田菁的生长。二、防治虫害。田菁枝叶繁茂,要特别注意防虫。如斜纹夜蛾幼虫为害,常可在二、三天内,把田菁叶子吃光。所以要及早检查,及时防治。对常见的害虫,如斜纹夜蛾、豆螈蜻、蚜虫和卷叶虫等,每亩用百分之九十的敌
Before and after the harvest of early rice, do a good job in the management of the rice field Jing, which is an important part of the high yield Tian Jing. For the characteristics of the growth of late Jing Jing, management should pay attention to the following aspects: First, fertilizer and water management. At this time, by the cyanine plant has been tall, lush foliage, the rapid growth of the internal sponge tissue, so water needs special fertilizer, so to irrigation deep water. Can be combined with summer farming, furrow furrow between Tian Jing line storage; early rice after harvest, the application of calcium phosphate per acre 10 to 20 pounds in order to accelerate the growth of Sesbania. Second, control pests. Tian Jing lush foliage, pay special attention to pest control. Such as Spodoptera lupus larvae damage, often in two or three days, the leaves of Jing Jing eat. So check as soon as possible, timely prevention and treatment. On the common pests, such as Spodoptera litura, soybean nymphs, aphids and leaf roller insects, with 90 percent per mu enemy
