选取新疆小白杏Prunus armeniaca为研究对象,在新疆吐鲁番亚尔乡布设覆盖全生物降解膜与无膜试验区,对比分析两试验区杏树4-6月生长期土壤水分、温度、养分及杏树生长(基径、新梢、叶)的差异性,并探讨了覆膜调温保墒的作用机制,结果表明:①与无膜区相比,4-6月份覆膜区0<H≤20 cm、20 cm<H≤40 cm及40 cm<H≤60 cm平均可分别提高3.3%、7.08%、12.6%; 4月份0<H≤60 cm土壤温度平均提高1.5 ℃,可显著降低高温期5月份0<H≤20 cm土层土壤温度,对同为高温期的6月份也有一定的降温作用;覆膜可促进土壤肥力的提升,但试验区土壤仍较为贫瘠。②覆膜可显著促进杏树的生长,覆膜区Ⅰ、Ⅱ、Ⅲ径级平均基径分别显著增加了11.86%、9.84%、11.80%,百叶质量分别增加了111.69%、5.11%、17.56%,平均叶面长≥6 cm,平均叶面宽≥4 cm,杏树径级越小,覆膜对杏树新梢的影响越明显。③全生物降解膜对土壤水分、温度的综合作用使得覆膜具有良好的调温保墒功能,同时促进杏树的生长。综上,在新疆杏树的栽培生产中可将覆膜技术进行推广应用,从而有效提高区域水资源利用率及农业生产效率。
Field experiments were conducted to study the effect of biodegradable film on the soil properties (moisture
temperature
and nutrients) and the growth of Prunus armeniaca (base diameter
new shoots
and leaf) during April to June in Tulufan
Xinjiang. The results showed that: ① the application of biodegradable film brought a significant effect on soil moisture and temperature
but not on soil nutrients. Soil water increased by 3.3%
7.08% and 12.6% at the depth of 0<H≤20 cm
20<H≤40 cm and 40<H≤60 cm from April to June. The average temperature of soil at the depth of 0<H≤60 cm in April increased by 1.5 ℃
while they relatively dropped at the depth of 0<H≤20 cm in May and June when the air temperature was high. Film coating can benefit soil fertility
but the soil of experimental zone was still relatively poor. ② Film coating can significantly accelerate the growth of Prunus armeniaca
e.g. the trees have stronger stems (the average basal diameter of Ⅰ
Ⅱ
Ⅲ diameter class increased by 11.86%
9.84% and 11.80%)
larger leaves (the median dimension was more than 6 ×4cm)
and heavier leaves (one hundred leave mass increased by 111.69%
5.11% and 17.56%
respectively
for Ⅰ
Ⅱ
Ⅲ diameter class). ③ The full biodegradable membrane can regulate the soil moisture and temperature
and hence benefits the growth of Prunus armeniaca. The biodegradable film should be applied generally to improve the water resources utilization and agricultural production efficiency in the apricot cultivation.
