Abstract

Abstract:

In the present study, the mature red jujube was used as experimental subject. Two irrigation levels (W1, 6 000 m³·hm^-2; W2, 6 600 m³·hm^-2), three base fertilization levels (denoted as S1, S2 and S3, with bio-organic fertilizer application rates of 1 200, 1 650, and 2 100 kg·hm^-2, respectively), were set, and the treatments without bio-organic fertilizer were set as controls (W1CK and W2CK) in the field experiment. It was shown that under the same irrigation level, with the increase of bio-organic fertilizer application rates, the branch length and width, leaf chlorophyll content, fruit morphology, available potassium, available phosphorus, and ammonium nitrogen content in 0-150 cm soil increased. With the elevated irrigation level, the contents of available potassium, available phosphorus and ammonium nitrogen in 0-150 cm soil decreased. Compared with the control, the yield per plant increased by 4.65%-19.83% under W1, and increased by 8.17%-19.08% under W2. The application of bio-organic fertilizer increased the contents of total sugar, soluble solids and vitamin C, and reduced the content of total acidity. The fruit morphology, yield per plant and quality indexes under W1S3 treatment were superior than those under W2CK treatment. Based on the climatic characteristics of aridity and low rainfall in Xinjiang, application of 2 100 kg·hm^-2 bio-organic fertilizer with an irrigation level of 6 000 m³·hm^-2 could replace the local conventional irrigation fertilization management, which is more suitable for jujube cultivation in the arid area of southern Xinjiang.

Key words: drip irrigated jujube, irrigation level, bio-organic fertilizer, soil nutrients, yield, quality
