从热量、光能、水分等因素上分析了云南利于种植早熟鲜食葡萄的农业气象条件;提出避开和防范葡萄生长期的灾害性天气。明确提出海拔1 000~1 500m,4、5月≥10℃的活动积温分别在600℃左右及700℃以上,年降雨量为600~900mm的地带为云南早熟鲜食葡萄的最适种植区,在其区内选择光照充足、有灌溉条件,土层深厚肥沃、排水良好的壤土和沙壤土地段建立种植基地。通过采取品种选择、设施栽培、疏花疏果、应用乙烯利催熟、石灰氮打破休眠、综合防治病虫害等技术措施,可在云南建立起大面积早熟鲜食葡萄的栽培基地。
From the factors of caloric, light energy and moisture, we analyzed the agro-meteorological conditions conducive to the cultivation of precocious grapes in Yunnan, and proposed the disastrous weather to avoid and prevent the grape growing season. Clearly put the elevation of 1 000 ~ 1 500 m, April and May ≥ 10 ℃ accumulated active temperature of about 600 ℃ and 700 ℃, respectively, the annual rainfall of 600 ~ 900mm area of Yunnan premature grapes for the most suitable planting areas, In its area, the choice of adequate lighting, irrigation conditions, deep and fertile soil, well-drained loam and sandy loam area to establish planting base. Through the selection of cultivars, cultivation of plants, thinning and thinning of flowers, ethephon ripening, breakage of dormancy with lime nitrogen, comprehensive prevention and control of pests and diseases and other technical measures, a large-scale precocious fresh grape cultivation base can be established in Yunnan.
