我队涂地是一九七一年九月关塘门的,总净面积372亩。在近两年试种了大麦、棉花、油菜等主要农作物获得成功后,为了进一步提高单产,我们遵照毛主席关于“还应该因地制宜地积极发展各种绿肥作物……”的教导,一九七三年下半年在涂地试播草子(苜蓿),由于没有经验,季节拖迟,生长不好,去年下半年我们在涂地上又试播了60亩(其中撒播40亩)。据地区农科所在一九七五年四月二十二日测产(测产前两天均为晴天)撒播的亩产7830斤,条播的3400斤,株高达91公分,茎粗也有0.3公分,主根长11公分。并由于草子根系的作用疏松了表土15公分左右。实践的结果打破了过去那种认为草子不能高产,涂地草子更难夺高产
Our team applied land to Kwun Tong Gate in September 1971 with a total net surface area of 372 mu. Following the success of major crops such as barley, cotton and rapeseed in the recent two years, in order to further increase yields, we follow Chairman Mao’s teaching on “Properly developing various kinds of green manure crops according to local conditions ...” In the second half of last year, we planted sowing seeds of grass (alfalfa). Due to lack of experience, the season was delayed and the growth was poor. In the second half of last year, we piloted 60 mu of land (including 40 mu of sowing land). According to the survey of agricultural production by the local agricultural institute on April 22, 1975 (the two days before the survey were sunny), 7830 kg per mu and 3400 kg were planted. The plant height was 91 cm and the stem diameter was 0.3 cm , The main root length of 11 cm. And due to the role of grass roots loose surface soil about 15 cm. The result of practice broke the past that canteens can not be high-yielding, more difficult to seize the high yield of grass
