从1964年开始,用接种根瘤菌在沙土地区试种红花草成功。1976年种了140亩,平均亩产达7,000斤鲜草,至1978年有的高达万斤以上。这对改良沙土,增加肥源,提高作物产量有明显效果。种植红花草的早稻平均亩产780多斤。在沙土地种植红花草有以下几点体会:一、作好种子处理:播种前将种子用轧米机回车,除去皮外的腊质,以利萌芽。并用40单位的“702”或用“5406”菌粉浸出液浸种。沙土种红花必须拌种根瘤菌,每亩用二并斜面培养的根瘤菌(斜面面积约50平方厘米),根瘤菌先用清水稀释,将种子拌匀,当天播完,防阳光直射,不要与酸、碱性的肥料混合,确保根瘤菌的活力。
From 1964 onwards, rhizobia inoculated with sand plants in the trial of saffron grass success. In 1976, 140 hectares were planted, yielding an average of 7,000 hectares of fresh grass per mu and up to 10,000 kilos in 1978. This has a significant effect on improving sand, increasing fertilizer source and increasing crop yield. The average annual yield of morning-safflower grass planting more than 780 kilos. Planting saffron grass in the sand have the following experience: First, make a good seed treatment: sowing before sowing the rice with a machine, remove the skin wax, to facilitate the bud. And use 40 units of “702” or “5406” powder leachate soaking. Sand soil safflower must be mixed with rhizobia, Rhizobium cultured with two and beveled per acre (slope area of about 50 square centimeters), Rhizobium first diluted with water, the seeds and mix well, broadcast the day end, against direct sunlight, do not Mix with acid and alkaline fertilizer to ensure the vitality of rhizobia.
