| In the facilities to promote early cultivation production, after chilling requirement of deciduous fruit trees complete accumulation, greenhouses begin to heat up (open quilt in the day and cover quilt in the night) and the heat is accumulated,which promote fruit trees germination. In this period air temperature rises rapidly, soil temperature rises slowly, both not harmonious, which cause delaying germination, flowering and fruit mature date. The reason, the soil temperature has reached the embryonic condition, but insufficient ground temperature of the grapes in the eco-inhibiting sleep. We select Golden grape as materials, after the chilling requirement of grape complete accumulation, set 5 treatments (corn stalks and sheep manure, corn stalks, rice straw, rice straw and sheep manure, sheep manure), analysis the effects of different organic ferment materials on grape growth and soil temperature, soil environment change. The results were as follows:1. Different organic stuffed hot real processing in different degree on soil temperature are has obviously upgrade role, which to corn straw sheep dung processing optimal, in soil 10cm, and 20cm, and 30cm and stuffed hot real Center, day average temperature than control respectively high out 1.98 ℃,and 2 ℃, and 2.06 ℃, and 4.03 ℃; Different organic stuffed hot real processing in soil 20cm, and 30cm of minimum, and Supreme temperature are significantly above control.2. Effects of different organic ferment materials for soil environment:soil organic matter content increased by 19.3%～61.23% compared with the control, soil total nitrogen, total phosphorus were increased by 9.1%～109.1%,21.43% to 50%. nitrogen, available P and K were increased by 32.87% ～85.27%,59.45%～92.37%,22.22%～83.33%, pH value decreased 2.76%-5.19%; soil fungi, bacteria were significantly increased,6.46～34.62%, respectively,38.3%～178.72%, a significant increase in the proportion of bacterial microflora in.3. Different organic grown grapes ferment and development:(1) early infancy 3-6d, early maturity 2～10d; (2) when the control of germination rate reached 53 percent, while other treatments germination rate They are:corn stalks sheep:85%, corn stalks:70%, rice straw sheep:64%, rice straw:62%, sheep:68%; (3) Before topping shoot, shoot length, respectively 61.77% higher than the control,56.50%,38.79%,23.54%,8.1%, positively correlated with the length of the stem diameter, but the difference was not significant; (4) of the grape leaf area significantly promoted, sheep manure with corn stalks the largest, the other descending order are:corn stalks> rice straw sheep> sheep> rice straw, respectively,19.11% higher than the control,14.94%,6.35%,3.3%, 2.42%; chlorophyll (5) in each treatment They were higher than the controls.4. Effects of different organic ferment materials on fruit quality and Yield:the appearance of the fruit quality sheep manure with corn stalks best fruits of different treatments soluble solids, total soluble sugar, titratable acid, vitamin C levels were higher than the control, integrated fruit quality of the targets were:corn stalks sheep manure> rice straw sheep> corn stalks> rice straw> sheep> control. Different organic ferment materials to enhance the grape yield, especially corn stalks sheep manure best effect, higher than the control 23.17%.In a word, organic ferment materials can improve soil temperature in winter, promote branch germination of fruit trees. At the same time, the germination rate increase, the fruit mature early. Using organic ferment materials not only reduce plant disease. improve soil environment but also improve the fruit quality and yield,which is play an important role in promoting early grape cultivation under facilities. |
