油果花生是江苏省射阳县高产优質的农家品种。1965年春,我县引种五百余斤,在全县十处进行了試种,計十三点七六亩,平均亩产二百五十五斤,較当地品种把子花生七点九亩,平均亩产九十八点九斤,增产158.2%。黄口基点播种的一点零八亩,亩产三百五十斤,較对比田二点九亩,平均亩产六十六点二斤,增产四倍多。通过一年的实践,油果花生表現出下列特点。1.具有丰产株型,适于密植。油果花生分枝直立丛生,株型紧凑,茎粗叶壮,結莢多集中在第一分枝上。据龙城农技站观察,单株第一分枝为四点三五个,結果二十一点九个,第二分枝一点三个,結果零点二七个,莢果在土壤中的分布范围直径一般只有十四至十七厘米,最大范围不超过二十五厘米,因此,宜于密植,一般每亩六千穴以上,能够充分利用地力和光能,增产潜力大。
Fruit peanut Sheyang County, Jiangsu Province, high-yielding high-quality farmhouse varieties. Spring of 1965, my county introduced more than 500 jin, ten counties in the county for trial planting, totaling 13.76 acres, an average of two hundred and fifty-five kg per mu, more than the local varieties handle peanuts 7.9 acres, The average yield of 98.9 kg per mu, an increase of 158.2%. Yellow Kouji sowing kind of 1.08 acres, three hundred and fifty pounds per mu, compared with two nine acres of fields, the average yield of 66.2 pounds, an increase of more than four times. Through the year’s practice, the fruit peanuts exhibit the following characteristics. 1. With a high yield plant type, suitable for close planting. Fruiting peanut branches erect clusters, compact plant type, thick stems and leaves, pods and more concentrated in the first branch. According to the Longcheng Agricultural Technology Station observation, the first branch of a plant was 4.3 points, with a result of 21.9 and a second branch of 1.3. The result was 0.27 and the pod was in the soil Distribution of diameter is generally only 14 to 17 cm, the maximum range of not more than 25 cm, therefore, should be close planting, generally more than 6,000 acre per mu, can make full use of geo-energy and light energy, yield potential.
