谷子在我省生产中占有重要地位,常年种植面积在500万亩左右,根据我省气候特点,有春播和夏播两种种植形式,春播谷子占全省谷子面积的40%以上,主要分布在张家口、承德、保定、唐山、秦皇岛等丘陵山区。根据谷子各生育期的需肥规律,进行科学施肥,对春谷增产起重要作用。现将春谷施肥技术简要介绍如下:一、基肥亩产400公斤以上的高产谷田,一般以每亩施农家肥5000—7500公斤为宜,亩产200—400公斤的中产谷田每亩施1500—4000公斤为宜。
Millet occupies an important position in the production of our province, perennial planted area of about 5000000 acres, according to the climate characteristics of our province, spring and summer sowing two planting forms, spring sown millet area of the province accounted for more than 40% of the area, mainly in Zhangjiakou, Chengde, Baoding, Tangshan, Qinhuangdao and other hills and mountains. According to the law of fertilization in each growth period of millet, scientific fertilization plays an important role in increasing spring yield. Spring Valley fertilization technology is now briefly described as follows: First, the base yield of more than 400 kg per mu high yield Valley, generally applied per mu farmhouse 5000-7500 kg is appropriate, 200-400 kg per mu of middle-yielding Valley per acre 1500- 4000 kg is appropriate.
