Encyclopaedia describes, and imperial No. two category Mid-late ripenings of hay, growing way is strong, plant type is compact, and tillering ability is strong, relatively cold-resistant, more anti-oriental sesame leaf Pinta, quality better, yielding ability are good.Suitably planted in Zhe Bei, eastern Zhejiang.

Zhejiang belong to subtropical monsoon climate, monsoon is notable, makes a clear distinction between the four seasons, year temperature it is moderate, illumination is more, and rainfall is plentiful, With the humid air, the hot seasonal variations of rain are synchronous, and climate resources preparation is various, and meteorological disaster is various.15~18 DEG C of average temperature of the whole year, 1 The moon, July are respectively that annual temperature is minimum and highest month, May, June are concentration flush period.44.1 DEG C of Extreme Maximum Temperature, - 17.4 DEG C of Annual lowest climate temperature；Zhejiang Province's mean annual rainfall is at 980~2000 millimeters, annual sunshine time 1710~2100 Hour.

Spring, East Asian monsoon are in the alternating season of winter wind direction wet monsoon conversion, and air-flow intersection in north and south is frequent, low pressure Aggravate with sharp side activity.For Zhejiang spring climatic characteristic to be sombre rainy, there is strong wind often in coastal and coastal waters, and Zhejiang Province's rainwater increases More, weather weather is indefinite, just so-called " spring my child's face, become within 1st three and become ".13~18 DEG C of Zhejiang spring temperature on average, temperature point Cloth feature is to be successively decreased from hinterland to coastal and Island；320~700 millimeters of Rainfall in Zhejiang Province amount, Rainfall distribution are By southwest, coastal area is progressively successively decreased northeastward；At 41~62 days on Zhejiang Province's rain day.Spring major weather disaster has wet weather, fallen Cold spell in spring etc..

Summer, as summer monsoon circulation system is established, Zhejiang southeaster prevailing within the border, the subtropics in northwest Pacific is high Pressure activity is had a major impact to Zhejiang weather, and cold air is gone down south in the north still has certain influence to Zhejiang weather.Zhejiang Province various regions Rain day is 32~55 days.Summer major weather disaster has typhoon, heavy rain, drought and waterlogging etc..

Autumn, wet monsoon progressively weaken, and to the transition of dry monsoon, cyclonic activity is frequent, and frontal precipitation is more, and temperature is cold It is warm to change greatly.16~21 DEG C of Zhejiang Province's autumn temperature on average, southeastern coast and middle part gas temperature drift, In Northwest Mountainous gas Temperature is relatively low；The coastal Precipitation in Mountain Area amount in 210~430 millimeters of precipitation, middle part and south is more, though northeast region precipitation is omited It is on the low side, but its Annual variations is larger；At 28~42 days on Zhejiang Province various regions rain day.

Winter, the power of East Asian winter monsoon depend primarily on the active situation of Mongolia high, and Zhejiang weather is limited by north Square cold air mass（That is dry monsoon）Influence, synoptic process species is relatively fewer.Winter climate feature is that fine cold short of rain, air is done It is dry.3~9 DEG C of temperature in winter, air temperature distribution feature are successively decreased from east to west to successively decrease from south to north；Various regions precipitation 140~ 250 millimeters, in addition to northeast island is on the low side substantially, remaining various regions difference is little；Zhejiang Province various regions rain day is 28~41 days.Winter Major weather disaster has cold wave, sleet etc..
