近年来,随着生产条件的改变,我区夏谷面积不断扩大,已发展到10多万亩。川水地一股亩产可达300斤左右,高的500斤以上。这就为实现两种两收或三种三收、粮食亩产超千斤创造了条件。夏谷生产有三个特点,即“晚,小、短”。晚是种的晚;小是秆低穗小,根茎少;短是生育期短,从麦收后播种到早霜来临,只有90天左右。根据这些特点,为夺取夏谷高产,必须采取“三早一密”的栽培措施。三早(一)选用早熟品种可因地制宜地选用竹叶青、延夏谷、黄沙谷、辽东黄、伏谷、志丹60天等优良品种。(二)力争早播夏谷提早播种是夺取高产的一个关键。我区无
In recent years, with the change of production conditions, the area of Summer Valley in our district has been constantly expanding and has developed to more than 10 million mu. A yield of about 300 kg per mu of Sichuan water, high 500 pounds or more. This created the conditions for achieving two kinds of two harvests or three kinds of crops and three crops per mu for grain production. Summer Valley production has three characteristics, namely “late, small, short.” Late is a kind of late; small straw is low spike, less rhizomes; short is short growth period, sowing from wheat to early frost, only 90 days or so. According to these characteristics, in order to seize the summer grain yield, we must take “three early and one close” cultivation measures. Three early (a) selection of precocious varieties can be selected according to local conditions bamboo Ye Qing, Yan Xia Gu, yellow sand valley, Liaodong yellow, V Valley, Zhidan 60 days and other fine varieties. (B) strive to early broadcast Summer Valley early sowing is a key to winning high yield. My area without
