| 摘 要： | 以4、7、10 a生“红富士”苹果为试材,研究不同覆沙年限对土壤含水量、土壤温度及苹果产量的影响.结果表明:果园覆沙主要在苹果开花期之前有增温效应,可明显提高0～20 cm土壤地温2℃左右；覆沙4～7 a保墒效应明显,10 a后逐渐减弱,需要换沙.

| Abstract: | Taking 4 years,7 years and 10 years old apple as test materials,the effects of different sand mulch years on the soil water content,soil temperature under different growth stages and yield of apple were studied.The results showed that the sand mulch could increase the temperature variation of topsoil about 2℃ in 0~20 cm before apple flowing;The sand mulch under 4~7 a increased the soil moisture content compare with the sand mulch under 10 a,but it abatedabate abate abate gradually the soil moisture content after 10 a and it need changed. |
