The Haiyang Climatic Conditions Analysis in Spring Sowing Period
Abstract: Haiyang City is an agricultural city. The main spring crops are peanuts, corn, sweet potatoes, taro and so on. Perennial sown area of spring crops is about 30,000 hm2. In order to utilize the climate resources rationally, while avoiding the disadvantages, this paper carried out the regression analysis and Mann-Kendall test analysis on the climate conditions during spring sowing period, according to the recent 55a meteorological data. The results show that: 1) The average yearly temperature sequence changes in Haiyang City during spring sowing period are tending to increase. The climate tendency rate is 0.28˚C/10a, the spring sowing period gradually comes earlier. 2) The average yearly precipitation sequence changes are tending to decrease but the climate tendency rate is very low. Less precipitation and the high chance of spring drought are the main factors influencing the spring sowing.
