永宁县养和公社王太十队1973年种了30.4亩杂交高粱,获得了平均亩产1,489斤的高产成绩。其主要技术措施是: 1.播前整地,疏松土壤:我们种植杂交高梁的田都是老旱田,土壤结构较好,其中22亩前茬是复茬糜子,4亩是重高梁茬地,4亩是坷垃田。糜茬地头年秋天机耕一遍,1972年冬1973年春又耙了三遍,碾了二遍,地化冻后,和高粱茬地、坷垃田又一起普遍犁两交,耙耱磙地各一遍,经过这样多次耕、耙、耱、磙,不仅破碎了坷垃,加深了耕作层,疏松了土壤,而且也保住了墒气,为高粱扎根出土和生长创造良好条件。 2.把好播种关,全苗是关键:播种时我们主要把了“三关”。一是整地关。除田平、土细、墒足外,犁地时做到边犁边耙、边耱(或边磙),播种时也做到边播、边耙、边磙。二
Yongning County Yanghe commune Wang Tai 10 team planted 30.4 acres of hybrid sorghum in 1973, obtained an average yield of 1,489 catties of high yield. The main technical measures are as follows: 1. Pre-sowing and earth-loosening soil: The fields we planted the hybrid sorghum are old dry fields and the soil structure is good. Among them, 22 mu of former crop is stubble mulberry, 4 mu is heavy barley crop, 4 Mu is Ke rubbed fields. Mi stubble in the first year of autumn machine again, the spring of 1972, the spring of 1973 and rake again three times, grind two times, after the freeze, and sorghum stubble, Pei Ju Tian common Plow two cross, rake shy again, after This multiple tillage, rake, trowel, trowel, not only broken Kejue, deepen the tillage layer, loose soil, but also to keep the moisture, for the root of sorghum rooted and create good conditions. 2 good seeding, the whole seedling is the key: when we sow the main “three off.” First, land preparation. In addition to Tian Ping, soil fine, soil moisture foot, while plowing plow rake edge, edge 耱 (or edge 磙), sowing is also done while sowing, edge rake, edge 磙. two
