花生单位面积的荚果产量,是由亩株数、单株结果数和果重三个因素构成的。三个因素协调与否,是权衡产量高低的重要标志。为找出适合我县栽培条件的群体结构指标,我们连续几年进行了密度试验。所用品种为花27、白沙1016及伏花生。各设九种处理,即分别为每亩7000、8000、9000穴三种穴数和每穴2、3、4粒三种粒数。小区面积0.03—0.05亩,重复三次。现将结果整理如下: 1、在每穴3粒的情况下,荚果产量随着穴数的增加而增加。每穴7000、8000、9000穴的平均亩产分别为370斤、382.6和385.8斤。而增产机率以每亩8000穴的为高,在几处试验中,产量占第一位的,7000穴的2处、8000穴的7处、9000穴的4处。再从实际增产效益看,每亩9000穴虽比8000穴的多产荚果3.2斤,但其播种区(每亩45.88斤)比8000穴的多5.1斤。增产数还抵消不了增加的播
Peanut per unit area of pod yield, is the number of acres, the number of fruit per plant and fruit weight of three factors. Coordination of the three factors or not is an important indicator of the level of production. In order to find out the group structure index suitable for the cultivation conditions in our county, we conducted the density test for several years. Varieties used for the flower 27, white sand 1016 and peanut. Each set of nine kinds of treatment, namely, respectively, 7000, 8000, 9000 points per acre three holes and 2,3,4 grains per hole three kinds of grain. Area of 0.03-0.05 acres of plots, repeated three times. The results are now organized as follows: 1, in the case of three grains per hole, pod yield increases with the increase of the number of points. The average yield per 7000, 8000 and 9000 holes is 370 kg, 382.6 and 385.8 kg respectively. The rate of increase in yield per acre 8000 points for the high, in several tests, the output accounts for the first place, 7,000 points in 2, 8,000 points in 7, 9000 points in 4 places. However, from the actual production efficiency, although 9000 points per acre than 8000 points more than the yield of 3.2 pods, but the sown area (45.88 kg per acre) than the more than 8000 points 5.1 kg. Increase the number can not offset the increase in broadcast
