冬小麦精播高产栽培法(以下简称“精播”),1992年11月获国家科技进步二等奖。该课题通过十多年的研究,从理论和实践上证明“精播”不仅比大肥,大水,大播量的传统高产栽培增产(一般可实现亩产500公斤左右.高的可达600多公斤),而且低耗费高效益,同一品种在精播条件下,每生产50公斤生物产量所吸收的氮平均为0.575±0.085公斤.磷(P_2O_5)平均为0.235±0.022公斤,与传统高产栽培的相比基本一致,而每生产50公斤经济产量所吸收的氮平均为1.195±0.017公斤,磷(P_2O_5)平均0.490±0.065公斤.显著低于传统高产栽培条件下所吸收的氮、磷量. Winter wheat sowing high-yield cultivation method (hereinafter referred to as “sowing ”), in November 1992 by the national science and technology progress prize two. Through more than a decade of research, this subject proves in theory and practice that “fine sowing” not only produces more yield than the traditional high-yielding cultivation of large fat, big water and large sowing (generally it can achieve about 500 kg per mu. Up to more than 600 kilograms), and low cost and high efficiency, the average nitrogen absorbed by the same variety in the precision sowing of 50 kg biomass production was 0.575 ± 0.085 kg, phosphorus (P 2 O 5) was 0.235 ± 0.022 kg on average, Compared with the high yielding cultivation, the average nitrogen absorbed by the economic output of 50 kg was 1.195 ± 0.017 kg and the average phosphorus (P_2O_5) was 0.490 ± 0.065 kg, which was significantly lower than that of the nitrogen and phosphorus absorbed by the traditional high yielding cultivation the amount.
