摘要
以核桃和豌豆为研究对象,研究了滴灌条件下核桃和豌豆植株灌水量和植株生长性状指标。结果表明:滴灌时核桃灌溉次数较人工浇灌少了11次,单株年用水量和试验区年总用水量较人工浇灌减少了76.58%,豌豆滴灌时比人工浇灌灌溉方式的灌水量减少了78.67%;滴灌灌溉较人工浇灌在核桃株高和胸径指标上长势更优,滴灌灌溉下根系密度较人工浇灌增加了4.67%,地上生物量指标中,鲜重和干重分别较人工浇灌提高了9.23%和6.42%,在地下生物量指标中,采用滴灌灌溉方式的鲜重和干重指标较人工浇灌增加了7.80%和5.70%;在灌水量相差悬殊的情况下,植株附近不同土层的土壤含水量和土壤温度差异很小。
Taking walnut and pea as the research objects,irrigation quantity and growth traits of walnut and pea under drip irrigation are studied.The results are as following：compared with pour irrigation,the irrigation times of walnut under drip irrigation is reduced by 11 times,annual water consumption per plant and total annual water consumption under drip irrigation in the test area are reduced by 76.58%,the irrigation quantity under drip irrigation is reduced by 78.67%;the plant height and DBH of walnut under drip irrigation are more superior,the root density is higher by 4.67%,the fresh weight and the dry weight in aboveground biomass index are increased by 9.23% and 6.42%,respectively;while in underground biomass are increased by 7.80% and 5.70%,respectively;when irrigation quantity is quite different,the soil water content and temperature difference in different soil layer nearby plant are little different.
