根据水稻产量的95％以上来源于空间营养(光合作用)这一原理,为使稻田光、热、气诸因素协调,黑龙江省依兰县团山子乡农技推广站与灌溉试验站协作进行了宽行双条与超稀植的间比试验。本试验设两个试验点相距4公里,每个试验点都设A、B两种处理四次重复,随机排列。 A处理:行距60厘米,每行双条,条间距离20厘米,穴距13厘米,每穴基本苗3株。 B处理(对照):行距30厘米,单条穴距13厘米,每穴基本苗3株。试验小区面积67平方米、南北垅向,单灌单排。两种处理每平方米都是25穴,株数也相同。品种均为“腾系128”其它管理措施相同。试验结果表明,两种处理成本相同,A处理平均627公斤/亩,B处理平均567公斤/亩。A处理比B处理增产10％。
According to the principle of space nutrition (photosynthesis) that more than 95% of rice yield comes from, in order to coordinate the factors of light, heat and gas in the rice field, the agricultural extension station of Tanshanzi Township, Yilan County, Heilongjiang Province was cooperated with the irrigation experimental station The ratio between wide double row and ultra-thin planting. The test set up two test points 4 km apart, each test point is set A, B two treatments repeated four times, randomly arranged. A treatment: Row spacing of 60 cm, two lines per row, the distance between bars of 20 cm, 13 cm hole distance, three per hole seedlings. B treatment (control): 30 cm spacing, single hole distance 13 cm, 3 per hole seedlings. Experimental plot area of ?? 67 square meters, north and south to the single irrigation single row. The two treatments are 25 points per square meter, the same number of strains. Varieties are “Teng-line 128” the same other management measures. The test results show that the two treatment costs the same, A treatment average 627 kg / mu, B treatment average 567 kg / mu. A treatment than B treatment yield 10%.
