沙漠绿洲多功能高分子植物生长调节剂籽瓜增产和品质改善研究

Effect of Multi-functional Macromolecule Plant Growth Regulator on Seedy Melon Production Increase and Quality Improvement in Minqin Desert Oasis

选择适合当地土壤和生态环境特点的优质高产籽瓜品种——新籽瓜1号，进行甘肃省武威市民勤沙漠绿洲多功能高分子植物生长调节剂籽瓜根部追施增产和品质改善试验研究。结果显示，施用产品不但有利于籽瓜的营养和生殖生长，增加瓜径3％～5％、提高产量11．5％，而且显著改善籽瓜的品质，提高其粗蛋白和维生素B1、B2含量。分别比对照增加1．80％和29．41％、14．29％，因而产生较好的经济效益，净增产值358．95～580．95元·hm^-2。

The new seedy melon breed No. 1 has high grade and high yield, and adapts to the local soil and environmental characteristics, Minqin desert oasis, Wuwei district, Gansu province. Thus, it was selected to carry through the seedy melon production increase and quality improvement experiment by the multi-functional macromolecule plant growth regulator which was drilled at the root part after seedling. The results were shown as the growth, output, quality and economic indexes. Comparing to the control seedy melon, the experimental group diameter increased from 3 % to 5 %, the yield increased 11.5 %, the crude protein content increased 1.80 %, and the vitamin B1 and B2 contents increased 29.41% and 14.29%, separately. These phenomena indicated that the use of this plant growth regulator not only made for the seedy melon nutritional and breed growths, but also improved its quality, significantly. Furthermore, the use of this product could elevate the net increase production value from 358.95 RMB· hm^-2 to 580. 95 RMB·hm^- 2.
