1982年松江县五里塘公社开始引种,连续两年获得高产。1983年种植200多亩,种子场80亩获亩产983.5斤,较对照、当地一般品种增产15～20％。栽培要点如下: (一)适时播种育壮秧:作单季稻种植全生育期150～160天。作油菜、小麦茬单季稻栽培,秧田播种期在5月10～20日,最迟不超过5月25日。播量每亩80斤,秧龄约35天。在精做秧板、施足有机肥的基础上,于一叶一心施15斤左右硫酸铵作断奶肥,三叶期少量补施接力肥,以利培育带蘖壮秧。 (二)合理密植争足穗:紫金糯是多穗型的矮秆品种,栽插密度应适当高些.以每亩2.5万穴,每
1982 Wuli Tang Songjiang County commune began introduction, for two consecutive years to obtain high yield. 1983 planted 200 acres, 80 acres of seed fields per mu 983.5 pounds, compared with the control, the local general varieties increased 15 ~ 20%. Cultivation points are as follows: (A) timely sowing strong seedlings: a single crop of rice for the whole growth period of 150 to 160 days. For canola, wheat stubble single-cropping rice cultivation, seedling sowing period in May 10 to 20, no later than May 25. Seeding rate of 80 pounds per mu, seedling age of about 35 days. In the fine seedlings, Shi adequate organic fertilizer on the basis of a leaf Shi Shi Shi Jin about 15 pounds of ammonium sulfate for weaning fat, clover a small amount of supplementation of fertilizer, to facilitate the cultivation of tiller seedlings. (B) the rational close planting fight spike: Zijin waxy is a more spike dwarf varieties, transplanting density should be appropriate higher to 25,000 acre per acre, each
