一、问题的提出龙泉公社水稻生产这些年来有很大发展,产量也在逐渐提高。1960年以前,这里水肥条件是差的,水稻品种多是大白谷、背子谷、大李子红、小白谷等低产水稻品种,这些品种的特点是需肥不多,发棵少。每亩栽下2—3万丛,每丛3—4片(合每亩8—9万基本苗)收获时每亩十万穗左右,单产只有四、五百斤。 1960年以后,水肥条件逐年有所改善,推广了发棵较好的“129”、“373”、“云梗二号”,“云梗九号”“310”等优良品种。为了良种良法配套,密植方式
First, the issue raised Longquan commune rice production has developed greatly over the years, production is also gradually increased. Before 1960, the water and fertilizer conditions were poor here. Most of the rice varieties were low-yielding rice varieties such as Da Baigu, Zi Zi Gu, Da Li Zi Hong, Xiaobai Gu and so on. These varieties are characterized by little need for fertilizer and few hair trees. Planted 2-3000 clumps per mu, each bundle of 3-4 (8-9 million per acre basal seedlings) harvest about 100,000 spikes per mu, yield only four or five pounds. After 1960, the conditions of water and fertilizer improved year by year, promoting the better varieties of “129”, “373”, “Yuntan 2”, “Yunjiu 9” and “310”. In order to support good varieties of good law, close planting way
