去冬,从中国农林科学院、北京作物所、江苏农科所等单位引进一批墨西哥等国外小麦品种。因种子量很少,采用粒播。畦宽三尺,畦沟一尺,横条播,行距六至八寸,粒距一寸半至二寸,每品种种二、三行。因考虑这些品种生育期长,提早于十月三十日播种,基肥用人粪尿集中沟施,每亩约三十担。垃圾土盖种。播后沟灌水一次。追肥三次,每亩人粪尿四十担。因今年雨水偏多,施肥多,所有品种长得浓绿,偏旺,根浅、株大,到二月份暴雨后普遍发生倒伏,经过间苗、拉黄叶、用竹竿绑扎等措施,基本上都收到了种子。现将试种情况简报如下:(见表)
To winter, from the Chinese Academy of Agriculture and Forestry, Beijing Crops, Jiangsu Agricultural Science and other units to introduce a number of foreign wheat varieties such as Mexico. Due to the small amount of seeds, the use of sowing.畦 wide three feet, 畦 groove a foot, horizontal sowing, row spacing of six to eight inches, grain distance of an inch and a half to two inches, each species of two or three lines. Due to the long period of growth of these varieties, sowing early on October 30, the concentration of manure on basal fertilizer is about 30 tons per mu. Landfill cover. Sowing ditch irrigation time. Topdressing three times, forty people per mu of human waste urine. Due to the large amount of rain and fertilization this year, all varieties grow thick green, strong, light and broad, and generally fall down after the heavy rains in February. Through the measures of thinning, yellowing and binding with bamboo rods, basically all Received the seeds. Briefing on the trial planting situation is as follows: (See Table)
