ABSTRACT

The aim is to explore the different sand covering patterns of barbary wolfberry in saline-alkali land (no sand covering as a control, Fine sand covering of 5cm, Fine sand covering of 10cm, 10cm, The effect of coarse sand covering 5cm) on soil water and salt transport and the growth and yield of wolfberry. Using 3a sheng 'Ningqi No. 1' barbary wolfberry as the test material to determine the soil moisture content of 0~100cm in different growth periods, pH, Salt content and composition, etc. The results show that: compared with no sand cover, Under the condition of sand covering, the soil water content during the barbary wolfberry growth period was significantly improved, and the soil pH and whole salt content of saline-alkali land were effectively reduced, and the thickness of coarse sand covering was 5cm, and the salt ion Na was optimal+, K+, SO2, Cl-. The inhibitory effect is more prominent. At the same time, different sand covering treatment also promoted the growth and development of Chinese wolfberry, and the branch length increased on average 15. 22%, Barbary wolfberry The yield of all reached extremely significant levels, The 5cm yield, Net income and production and investment ratio are the best, 19. 64%. For the cultivation of barbary wolfberry in saline-alkali arid areas, the overall salt suppression effect of 5cm is the most significant, which is an effective coverage method for the continuous and stable production of barbary wolfberry in Hongsibao irrigated area.
