Research on Wolfberry Irrigation and Mulching Measures ...

Abstract

Chinese wolfberry (Lycium barbarum L.) is Atropa (Solanaceae) is a Chinese wolfberry (Lycium Linn.) Of a small deciduous shrub. Barbarum rapid increase in consumption, the corresponding driven the rapid development of industry[1.2]. Chinese wolfberry with ecological, economic, social “trinity” of the significant benefits and the “medicine food homology” superiority complex.In this study, based in Waterloo Jingtai County, Gansu Province caowotan standardized wolfberry cultivation mu demonstration base, the test material for the one-year-old Ning Qi 1, established planting furrow irrigation are located 4275 m3/(hm2·a), 4725 m3/(hm2·a), 5175 m3/(hm2·a) three irrigation, irrigation water in each film are located under the coverage, fine sand covered with straw covered the difference in treatment by measuring the moisture content of leaves, soil moisture content, level, branch diameter, crown , plant height, fruit yield and average 100-seed weight and so on, using analysis of variance to evaluate the following conclusions:1. The role of three types of coverage measures have good water effects, can be effective to reduce water evaporation and increase soil moisture and leaf moisture content. Ability of three types of coverage measures as follows: plastic> straw> fine sand.2. Three coverage measures can significantly promote the growth of Chinese wolfberry, a branch of the Chinese wolfberry average stem diameter, diameter, crown width, height, etc. to promote the role of descending is / are: plastic cover> straw mulch> sand cover.3. Three coverage measures can improve the output of Chinese wolfberry, and increase the fruits of 100-seed weight to improve the quality of fruit to increase fruit quality fruit can reach the aim of increasing efficiency, three types of coverage in the plastic-covered yield the best efficiency, followed by straw mulch, and sand cover. 4. From the size of irrigation, the irrigation (4725 m3/(hm2·a)) Chinese wolfberry fruit growth and yield and quality are better than the other two irrigation (4275 m3/(hm2·a),5175 m3/(hm2·a)). Fixed for the use of irrigation in sub-embryonic 4725 m3/(hm2·a) before May 20, June 20, July 20, August 20 and 6 times after deciduous shrub Lycium End can meet the strong growth of the moisture needs.Comprehensive analysis of these conclusions, we can see that the use of furrow irrigation ditch way of planting, irrigation in the fixed combination of coverage for plastic 4725 m3/(hm2·a)water measures, in organic (sheep) 5kg / strain, enables one-year-old Ning Qi to reach No. 1 high quality and efficient water-saving purposes.
