在推广早稻温室无土育秧中,由于种谷无法固定,随着根苗的生长引起翘根倒苗,用镇压方法虽可制止,但费时费工,且易折断秧苗。又因保水性差,一些秧苗根长苗短,秧苗不够健壮等。为了解决这些问题,我们进行了早稻温室无土盖沙试验。从两年试验情况看来,温室无土盖沙育秧具有不需镇压,减少喷水次数,能起到控根促苗,抑制病害发生,达到提高秧苗素质的作用。试验稻种为南优2号(一般不作早稻,我们试想用早播早插的方法,结合做一次杂交水稻一种两收
In the promotion of early rice greenhouse soilless seedlings, due to the seedless can not be fixed, with the growth of root seedlings caused by Alice root downing, with the suppression method can be stopped, but time-consuming and laborious, and easy to break seedlings. Because of poor water retention, some seedlings are short seedlings, seedlings are not robust enough. In order to solve these problems, we carried out the early rice greenhouse soilless cover experiment. From the two years of trial situation, greenhouse soilless cover seedling with no need to suppress, reduce the number of water, can play a controlled role in promoting seedling, suppression of diseases, to improve the quality of seedlings. The test rice species is Nanyou 2 (generally not for early rice, we try to use the method of early sowing and early planting, combined with a hybrid rice to do a two income
