Abstract
A method for increasing the yield of cryophilous plant in low-latitude region features that the winter or semi-winter plants except the cabbage-type rape can be planted in the region being to the south of 32.5 deg.N and the winter or semi-witer cabbage-type rape can be planted in the region being to the south of 27 deg.N.
Description
Technical field.The invention belongs to field of agricultural production technologies.Be specifically related to the method that the plant planting kind is selected.
Background technology.For a long time, owing to be subjected to traditional plant vernalization Theory Influence, 32.5 ° of N areass to the south are considered to the winter habit except that cabbage type rape, the forbidden zone that semiwinterness is liked cool plant variety.And 27 ° of N areass to the south are considered to the forbidden zone of winter habit, semiwinterness cabbage type rape variety.It is believed that at low latitudes, because winter temperature is low inadequately, the winter habit semiwinterness is liked cool plant variety and is difficult to that is to say that by entering generative growth phase vernalization stage these kinds can not be bloomed at low latitudes, and will be solid.And spring varieties since its tiller, a little less than the branch ability, vegetative period is short, drought resistance, cold resistance are poor, output generally than winter habit semiwinterness kind low yield 50% (tricky behaviour's select chief editor, each opinion of crop cultivation, south this, Beijing, agriculture publishing house, 1994 years; The Jin Shanbao chief editor, Chinese wheat is learned, Beijing, Chinese agriculture publishing house, 1996; The chief editor of Inst. of Oil Crops, Chinese Academy of Agriculture, china rape cultivation, Beijing, agriculture publishing house, nineteen ninety).
Summary of the invention.Purpose of the present invention is that the output that low latitudes will be liked cool plant is enhanced about more than once.Comprise the inventor numerous scientists studies show that winter habit, semiwinterness are liked in the cool plant variety, some kind needed low temperature in vernalization stage can be replaced by short day.And low latitudes, the sunshine in its winter is exactly shorter.And some winter habit, semiwinterness are liked cool plant variety, neither need low temperature its vernalization stage, also do not need short day, promptly do not have vernalization stage.Particular content of the present invention is, use winter habit, semiwinterness except that cabbage type rape to like cool plant variety 32.5 ° of N areass to the south, use winter habit half, winter habit cabbage type rape variety 27 ° of N areass to the south, make low latitudes like cool plant products and double.
Embodiment 1 with big No. 2 spring varieties such as replacement Mianyang 30 in wheat semiwinterness kind sea, makes wheat yield be increased to 500 kilograms by 250 kilograms at Upper Yangtze River Mai Qu.
Embodiment 2 in south China plantation with winter habit rape variety oil king No. 3, its per 667 meters
2Output can reach 350 kilograms.
Embodiment 3 plants semiwinterness cabbage heart kind green moss No. 1 in south China, make cabbage heart output by per 667 meters
2Bring up to 5000 kilograms for 1000 kilograms.
Embodiment 4 plants winter habit semiwinterness broad bean kind sea beans No. 1 in the areas to the south, the Changjiang river, make broad bean output by per 667 meters
2Bring up to 300 kilograms for 150 kilograms.
Embodiment 5 plants the big beer barley in semiwinterness malting barley variety sea No. 1 in the South China, per 667 meters
2Output reaches 400 kilograms.
