Saline-land salt-water drip-irrigation medlar cultivation method

Abstract

The invention provides a method for cultivating Chinese wolfberry in a saline and alkaline land through drip irrigation with saline water, which comprises ridging, planting and irrigation management, and is characterized by comprising: A, a step of manual ridging; B, a step of planting, in which the row spacing is 3 meters and the plant spacing is 1 meter; C, a step of drip irrigation zone setting, in which a single drip irrigation zone is arranged in a single ridge; D, filming covering and irrigation, in which spring irrigation is performed after film covering with local underground saline water in a mount which is four times of that used for daily irrigation continuously for three days till the water accumulates to a fixed amount of 16 millimeters; E, a step of pruning the Chinese wolfberry in a growth season; and F, winter irrigation, in which winder irrigation is performed once after the growth season of the Chinese wolfberry with 16 millimeters of water. According to characteristics of a saline and alkaline land in the groundwater area, the method maintains the water potential in the soil of the root area of the Chinese wolfberry at a constant higher value through ridging, filming covering and saline water drip irrigation and other measures to ensure Chinese wolfberry absorbs water normally and grows, thereby providing a good growing environment for the Chinese wolfberry and increasing the output and quality of medlar. Meanwhile, irrigation with local underground saline water reduces the water level of underground water and reduces the risk of further raising the water level of ground water due to irrigation with extraneous water.

Description

technical field [0001] The invention relates to a saline-alkali land salt water drip irrigation method for wolfberry cultivation, and belongs to the technical field of saline-alkali land management and planting. Background technique [0002] Saline-alkali land is an important land resource for agricultural development and utilization. According to the second soil census in my country, the area of ​​saline-alkali land resources in China is nearly 100 million hm 2 , of which the modern saline-alkali soil area is about 37 million hm 2 , the remaining saline soil is about 42 million hm 2 , the potential saline soil is about 17 million hm 2 . Agricultural development and utilization of saline-alkali land has great development potential. [0003] It is difficult for plants to grow or yield very low on saline-alkali land, mainly because the soil salt in the root zone of the plant affects the normal growth of crops in terms of infiltration and ion toxicity. Therefore, to devel...

Problems solved by technology

With the development of various goji berry products, the market demand for goji berries is increasing. Considering the saline-alkali tolerance of goji berries, a large number of goji berries have been planted on saline-alkali land. Resistant to waterlogging, low survival rate and low yield often occur, and the economic benefits are very poor. Therefore, planting wolfberry in shallow groundwater buried areas has not been developed.
