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.
