2011年龙江县玉米农田土壤湿度变化及其对玉米生长的影响

Abstract

Abstract: The main maize variety (Huke 336) in Heilongjiang province was treated with the contrast observation under natural conditions in the maize field, and the effect of different soil moisture on maize growth was analyzed. The results show that soil moisture in the different surface layers (0-30 cm) is in a decreasing tendency in 2011 in Longjiang maize field. The effect of soil moisture in different soil layer on maize growth is different. It has a significant effect on green leaves area and dry weight. Within a certain soil moisture range, the leaf area will increase 28.338 cm² if soil moisture increases 1%. Suitable surface soil moisture is favorable to increase green leaf area and dry matter of maize.

Key words: Maize, Soil moisture, Green leaf area, Dry matter
