1983年我们在早晚稻生产中大力推广了叶面喷肥这一措施,全县早、晚稻面积共达14.7万亩,都获得了一定增产效果。据试验和调查,早稻一般增产4.6—10.9％,二晚增产6.6—8.2％。应用这一措施开始是1982年马埠公社夏塘村农户陈九根在2亩二晚田中于齐穗期喷施磷酸二氢钾,结果比未喷施的每亩增产稻谷55斤,尝到了甜头。83年又用8斤磷酸二氢钾,对18亩早稻,12亩二晚在齐穗期全部进行了叶面喷肥,全年增产稻谷1240斤,每亩平均增产稻谷40斤。巴邱镇彭家村农户彭志敏,83年在二晚754田中,有2亩喷施了磷酸二氢钾,亩产达752斤,比未喷施的每亩增产稻谷152斤,增产25.(?)3％。为探讨这一技术措施的增产效果,并为大面积推广作示范,1983年全县对水稻叶面喷肥布置了定点试验,计早稻10个点,分设在马埠、砚 In 1983, we vigorously promoted the foliar fertilizer application in early and late rice production. The total area of ​​early and late rice in the county totaled 147,000 mu, all of which achieved some yield-increasing effects. According to tests and surveys, the general increase of early rice 4.6-10.9%, yield 6.6-8.2% two nights. The beginning of the application of this measure was started in 1982, the Mutu commune Xiaatang farmers Chen Jiugen in 2 acres of land for two nights later sprayed potassium dihydrogen phosphate, the results than the non-sprayed mu yield of 55 acres per mu, tasted the sweetness. 83 years and 8 kg of potassium dihydrogen phosphate, 18 acres of early rice, 12 acres of land for the second night in full heading foliar fertilizer, an annual increase of 1240 kg of rice, an average yield of 40 kg of rice per mu. Peng Zhimin farmers Peng Zhimin 83 villages in 83 two nights 754 Tanaka, 2 acres of potassium dihydrogen phosphate spraying, yield 752 pounds per mu than the non-sprayed per mu yield of rice 152 pounds, an increase of 25. (? ) 3%. In order to explore the stimulation effect of this technical measure and provide a demonstration for large-scale promotion, in 1983, the county laid out a fixed-point experiment on paddy foliar fertilizer, counting 10 points for early paddy, which were divided into Mabu and Yan
