| Abstract: | Field experiments were conducted to examine the effects of rice transplanting density and soil surface water depth on the interference of allelopathic rice in barnyardgrass Echinochloa crusgalli(L.) Beauv],difformed galingale(Cyperus difformis L.) and procumbent falsepimperne Lindernia procumbens(Krock.) Philcox].The results showed that HuangKangcao 78 could significantly control the plant numbers and dry weight of weeds when the rice transplanting density was 450~600 thousand seedling/hm2 and 10 cm water depth on soil surface was retained 15 days after rice transplanting,and which could increase the yield of HuangKangcao 78 markedly. |
