Description
Technical field
The present invention relates to the agricultural planting technique field, particularly the kind method for planting of a kind of corn-soybean strip cropping.
Background technology
Corn has become the first cereal crops of China, also is the highest cereal crops of whole world gross yield.Corn is very big at the sowing area of China, it is very wide to distribute, and is the crop of area and yield potentiality maximum in the cereal crops of nonirrigated farmland.Except edible, corn also is widely used in feed, raw material of industry field, as producing animal feeding-stuff, papermaking, brewageing liquor, manufacture alcohol etc.Because corn has many-sided outstanding advantage, its demand is increases situation year by year.
Soybean also is the important crops of China, and it integrates cereal crops, economic crops, feed and processes raw material, and processing chain is the longest.Soybean contains rich in protein, fat and multiple mineral nutrient element and physiological activator, because of its unique nutritive value, adds its nodule nitrogen fixation effect, and is significant to human lives and agricultural production.China is the country of soybean demand and import volume maximum in the world, and China's soybean import reached 5,264 ten thousand tons in 2011, and externally interdependency is up to 74.5%.It is predicted that before and after 2015, the maximum cultivated area of China soybean will reach 19,500 ten thousand mu, about 3,000 ten thousand tons of maximum productivitys, and domestic soybean aggregate demand is more than 5,400 ten thousand tons, the soybean supply demand gap will be about 25,000,000 tons.Therefore greatly develop the soybean planting industry, improving the raw soybeans degree of self-sufficiency is the important directions of China Agricultural Structure Adjustment.
In China the Yellow River and Huai He River sea plain district, Northeast plain district, northwest plateau district, area, southwestern mountain, there are a kind of corn and soybean interplanting mode, can give full play between two kinds of kinds between the crop reciprocal, reasonably combined by on the spatial framework between tall and big crop corn and the short and small crop soybean, realize the efficient utilization of light, heat, water, fertile resource, compare the yield per unit area that can improve crop with nonoculture.Corn and soybean intercropping mode have important effect in these regional extensive uses for alleviating the urgent demand of China to corn, soybean.
Yet, in current corn, soybean intercropping mode, there is the irrational situation of field layout, can't give full play to the advantage that interplanting mode efficiently utilizes resource, can't realize the agricultural production mechanization sowing, limited the raising of production efficiency.Therefore, provide a kind of corn-soybean strip cropping composite plant method that is suitable for the mechanization operation, have important practical significance for aspects such as guaranteeing the two high yields of corn and soybean, enhance productivity and promote the modern agriculture industry development.

Corn, soybean were sowed at the beginning of 2012 5 months, adopt eight row seeding monomer ploughs, interval between the eight row seeding monomer ploughs is 50cm, eight row seeding monomers are sowed corn, soybean, soybean, corn, corn, soybean, soybean, corn respectively, and reverse interval 50cm carries out the operation second time.Every plantation two row corns are planted two row soybean at interval, line-spacing between the two row corns is 50cm, line-spacing between the two row soybean is 50cm, spacing distance 50cm between corn and the soybean row, the cave distance of the corn seeding unit of sower is 19cm, 1 in every cave, the cave distance of the soybean seeding unit of sower is 7cm, 1 in every cave.Corn density 3500 strain/mus after planting, soybean density 9500 strain/mus.Corn nonoculture control group and soybean nonoculture control group are set, and corn nonoculture control group and soybean nonoculture control group all adopt local traditional planting patterns single cropping, control group and the experimental group sowing same period, and other field management is all consistent with the local land for growing field crops level of production.Treat to measure output after corn and the soybean maturation, and calculate the soil equivalent proportion of experimental group, result of the test sees Table 9.
The output of table 9 corn and soybean
By above-mentioned result of the test as can be known, corn per mu yield 376kg under the intercropping condition, soybean per mu yield 81kg under the intercropping condition, corn nonoculture control group per mu yield 425kg, soybean nonoculture control group per mu yield 129kg, the soil equivalent proportion of the kind method for planting of corn provided by the invention-soybean strip cropping is 1.51, and rate of growth reaches 51.3%, shows that provided by the invention kind of method for planting can realize two high yields of corn and soybean.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
