水稻抛秧是将传统的弯腰手插移植改为抛撒种植,一人一天可抛三四亩,秧苗浅栽早发,具有明显的省工省力、稳产高产特点。近年来,抛秧技术得到大力推广,1996年浙江省推广应用50余万亩,深受广大农户特别是种粮大户的欢迎。其中尤以早稻塑料秧盘育苗抛秧应用较为广泛。现将主要技术介绍如下。1.选择适宜的品种、茬口和田块因塑料秧盘育苗的播种密度较高,故只适用于培育叶龄3.5～5叶、苗高15厘米以内的秧苗。早稻适宜秧龄为25～30天,最长不超过35天。抛栽稻的根系分布比较浅, Rice throwing transplanting traditional bent over the hand to transplant planted planting, one day can throw three or four acres, seedlings planted early, with obvious labor-saving, stable and high yield characteristics. In recent years, thrown seedling technology has been vigorously promoted in Zhejiang Province in 1996 to promote the use of more than 50 acres, welcomed by the majority of farmers, especially large grain growers. Among them, early rice plastic seedling transplanting seedling more widely used. Now the main technical introduction is as follows. 1. Select the appropriate varieties, crop stubble and plots of plastic seedling tray seedling planting density is high, it is only suitable for the cultivation of leaf age 3.5 to 5 leaves, seedling height 15 cm within the seedlings. Suitable for early rice seedling age of 25 to 30 days, the longest no more than 35 days. Throwing planted rice root system is relatively shallow,
