西、甜瓜种子低温发芽试验的目的是检测在低温条件下,西、甜瓜种子的发芽适应力。我区地处新疆北部,主要经济作物之一是西、甜瓜。每年农民为抢占西、甜瓜早市,往往在4月初采取扣棚早播。但此时是春季化冻不久,地温尚低,虽铺膜加扣棚,地温也只有15℃左右,与常规发芽温度相差很大。如果此时我们采取常规发芽方法,得出的结果会与实际不符。因此,对早播西、甜瓜种子很有必要进行低温发芽试验,通过检验西、甜瓜种子在低温条件下的发芽率,来正确指导农民掌握播期及播种量。
West, melon seeds germination test is to test the low temperature conditions, the West, melon seeds germination adaptability. My area is located in northern Xinjiang, one of the main cash crops are West, melon. In order to seize the west and melon morning market, peasants often adopt early shedding in early April. But this time is the spring thaw soon, the ground temperature is still low, although the film plus buckle shed, ground temperature is only about 15 ℃, and the conventional germination temperature varies widely. If at this point we take the conventional method of germination, the results will be inconsistent with the actual. Therefore, it is very necessary to conduct low temperature germination test on early sowing west and melon seeds. By testing the germination rate of west and melon seeds under the condition of low temperature, we can correctly guide farmers to grasp the sowing date and sowing quantity.
