| 摘 要： | 为探究在不同水肥一体化处理下,对宁夏中部干旱地区土壤水分及苹果生长的影响,从而得到适应该地区的苹果灌溉制度,试验设置了低水(W1)2700 m^3/hm^2、中水(W2)3450 m^3/hm^2、高水(W3)4200 m^3/hm^2;低肥(F1)555 kg/hm^2、中肥(F2)675 kg/hm^2、高肥(F3)795 kg/hm^2,共9个组合处理。结果表明在各次灌水后土壤含水量发生显著变化,随着灌水量的增大,各层土壤含水量同期相应增大,各层土壤含水量均围绕60%田间持水量发生变化,在20~60 cm土层土壤含水量最大,在8.6%~28.7%之间变化;随着生育期的推进,当施肥量相同灌水量不同时各个处理之间的叶绿素相差不大,当灌水量相同施肥量不同时,随着施肥量的增加各处理叶绿素呈增加趋势。苹果的产量会随着灌水量与施肥量的增加而增加,且施肥量对苹果的产量较灌水量的影响大。基于苹果的产量与品质,综合得出5~6年生新红星苹果在平水年型(P=50%)下水肥一体化滴灌灌溉制度为最优为T5处理,在该处理下新红星苹果产量为6237~8318.85 kg/hm^2,作物水分生产率为1.21~1.60 kg/m^3。

| Abstract: | In order to explore the effects of integrated water and fertilizer on soil moisture and apple growth in the arid regions of central Ningxia,the apple irrigation system suitable for the region is obtained.The experiment sets low water(W1)2700 m^3/hm^2,medium water(W2)3450 mm^3/hm^2 and high water(W3)4200 m^3/hm^2,and three fertilizer treatments:low fertilizer(F1)555 kg/hm^2,medium fertilizer(F2)675 kg/hm^2 and high fertilizer(F3)795 kg/hm^2,a total of 9 treatments.The results show that the soil moisture changes significantly after each irrigation.With the increase in irrigation amount,the soil moisture of each layer increases correspondingly,and the soil moisture of each layer changes around 60%of field capacity.The soil moisture of the 20~60 cm soil layer is the largest,and the maximum soil moisture varies from 8.6%to 28.7%.With the advancement of the growth period,when the amount of fertilizer is the same and the irrigation amount is different,the chlorophyll content differs slightly.When the same irrigation amount and fertilization amount are different,the chlorophyll contents of each treatment increase with the increase in fertilizer application amount.The yield of apples increases with the increase in irrigation water and fertilizer,and the amount of fertilizer has a greater effect on the yield of apples than the irrigation amount.Based on the yield and quality of apples,it is concluded that in the Pingshui type(P=50%),the optimal irrigation scheme of 5~6 years new red star apple of integrated water and fertilizer is T5.Under this treatment,the yield of new red star apple is 6237~8318.85 kg/hm^2,water production efficiency is 1.21~1.60 kg/m^3. |
