PAM保水剂及纳米蒙脱土对果园生草地上部生物量的影响
Effect of PAM aquasorbent and nano-montmorillonite on the aboveground biomass of planting herbage in orchard
摘要
Abstract
With the water-saving purpose of orchard grass, a field experiment was conducted to study the effect of different amount of PAM aquasorbent (0, 4, 8 g/m2 and 12 g/m2) and different amount of nano-montmorillonite(0, 150, 300 g/m2 and 450 g/m2) on the aboveground biomass of different kinds of grass (Alfalfa, Ryegrass, White Clover) . The results indicate that under 50 % usual irrigation quantity condition, the use of PAM aquasorbent can significantly increase the total aboveground biomass of the three kind of grasses and the suitable amount is 8 g/m , while under the usual irrigation quantity condition, PAM aquasorbent should not be applied. The nano-montmorillonite is good for the increase of the total aboveground biomass, when the irrigation quantity was 50% of the usual irrigation quantity. The appropriate amount for the three kinds of grass is 150 g/m2, under the usual irrigation quantity, different kinds of grass need different amount, and 300 g/m2 is appropriate for White Clover, as for Alfalfa and Ryegrass, the amount of 450 g/m2 is suitable.关键词
