Effects Of Full Biodegradable Mulch Film On Growth Of The Prunus Armeniaca L. And The Physical And Chemical Properties Of Soil In The Turpan

In order to promote the development of the fruit industry in arid area, the efficient use of water resources to create environmentally friendly eco-fruit industry. In this study, the use of biodegradable film bagging plant technology in the city of Turpan,Xinjiang,China, established a biodegradable film by water-saving planting technology about Prunus armeniaca L. The test were subjected to two treatments: full biodegradable film, and no mulch. We continued to observe a complete growing season(April to August). Study biodegradable film covering the growth index of apricot, soil temperature and water, soil nutrients and soil salinity influence.By comparing the biodegradable film with no mulch about apricot growing conditions found: Biodegradable film for apricot three diameter classes average basal diameter have promoted, which promote Ⅰ、Ⅲ diameter class of more significant; Biodegradable film than those without the film promotes the growth of apricot crown, and promoted East-West crown stronger than North-South crown; film making apricot fruit diameter, longitudinal diameter and the number has increased to varying degrees; The apricot tree length of new shoots、width of new shoots and leaf number of new shoots were significantly greater in the biodegradable film treatment than in the no-mulch treatment. To promote shoot leaf number showing increasing trend month by month; The leaf length, leaf width, and 100-leaf weight were also higher in the biodegradable film treatment than in the no-mulch treatment, Increase the biodegradable film treatment leaf photosynthetic area, and enhance the photosynthetic efficiency of this area.Biodegradable film treatment can significantly improve soil moisture in different soil layers, Cumulative data show that while covering biodegradable film for the promotion of the role of near-surface soil water retention is relatively weak, With the deeper soil layers biodegradable film is the better water retention.Comparison of different months biodegradable film soil water effects role in promoting the discovery, the higher the temperature, the relative biodegradable film the better water retention. Apricot entire growing season, the biodegradable film covering the test area can effectively regulate soil temperature. April when the temperature is low near the surface of the soil covered with insulation effect, when in May, June, July, August treatment area into high temperature weather the biodegradable film having a near-surface soil a significant cooling effect.Biodegradable film portion after degradation can increase soil nutrient content. biodegradable film treatment of the three depths soil organic matter and soil organic carbon content than no-mulch treatment. By comparison, biodegradable film portion after degradation promoting 20~40cm of soil organic matter and soil organic carbon on the most significant. Biodegradable film treatment than no-mulch treatment total nitrogen, phosphorus, potassium and available nitrogen, phosphorus and potassium content have all increased. The degree of maturation of soil test area is poor, low fertility level, available nitrogen, phosphorus and potassium content of increase for the good growth of apricot provided favorable conditions.By comparing biodegradable film treatment than no-mulch treatment of three soil depths in Soil salt content discovery: biodegradable film treatment have an impact on soil salinity than no-mulch treatment but was not significant. Biodegradable film treatment than no-mulch treatment increasing soil salinity content of ionic membrane area mainly CO32-, Ca2 +, Mg2 +, the ion content is reduced mainly HCO3-, SO42-, Na +, K +. Two treatment area overall trend are about same eight ion distribution. The most abundant anions are HCO3-, the most abundant cationic are Ca2+. Soil test area most abundant salt is Ca(HCO3) 2.Comprehensive studies, these results showed that the use of biodegradable film mulch in an arid area can maintain higher soil water content and regulate soil temperature, thereby promoting the growth of fruit trees. This method can be applied in orchards and forests in arid areas, and therefore has far-reaching significance.
