A silage corn and fodder soybean mixture sowing method includes firstly, preparing farmlands which are few in weeds and easy to realize mechanical operation; secondly, sowing at the beginning and the middle of May according to the parameters of 30-37.5kg/hm of silage corns and 48-60kg/hm of fodder soybeans, by the detail steps of preparing the farmlands in the autumn, removing weeds by means of rotary tillage and applying organic fertilizer, flatting and ridging with the row space of 70cm, and then sowing in drill by a precision dibbler for mixture sowing, sowing the two kinds of seeds along different lines in different holes; thirdly, performing field management by detail steps of turning up the farmland and weeding in the seedling stage, eliminating tall weeds manually without chemical herbicides, and then intertilling 1-2 times in the jointing stage, and applying urea fertilizer; and fourthly, harvesting green grass mixedly in the wax ripening stage of the silage corns. The silage corn and fodder soybean mixture sowing method has significant yield increasing effect as compared with that of the clean culture method; yield of the stem leaves of the fodder soybeans is increased after the mixture sowing; and nitrogen elements are continuously supplied to the silage corns in the growing period by rhizobia of the fodder soybeans through nitrogen fixation, and effect of promoting yield increasing mutually is achieved.

The invention discloses a method for breeding maize stay-green and premature-aging resistant inbred line and a silage maize hybrid thereof. A maize stay-green and premature-aging resistant inbred line B31-3 is bred is as follows: the tropical maize population germplasm is taken as the basic material, and then the directional selection is carried out according to a pedigree method; the maize stay-green and premature-aging resistant inbred line B31-3 as the female parent is crossbred with a self-selected line P-64, and a silage maize single-cross hybrid, i.e., Yu Qingyu NO. 3, is bred in 2010. The silage maize hybrid has the advantages of strong growth power, large plant vegetative mass, field resistance, strong lodging resistance, ripe living plants, excellent seed quality, excellent nutrient quality of the whole plant, high biological production and the like; the time from emergence of seedlings to cutting is 126 days, the plant height is 3.03 m, the ear height is 1.33 m, the total number of leaves of the whole plant is 21-22 pieces, the average number of green leaves is 13.1 pieces, the ear length is 19.9 cm, the number of row of bald ear is 16.9, the grains per row are 35.5, the seeds are yellow and half horse-toothed, and the silage maize hybrid is suitable for planting in plain and hill areas in Chongqing, mid-low mountain areas, high mountain areas and similar ecological areas.

The invention discloses a chicory and ensiled corn mixed ensiling method. The method mainly solves the problems that chicory is not suitable to be separately ensiled due to high water and protein content and the ensiling cost is improved due to high digestion rate, low protein content and requirement for exogenous additive when the ensiled corn is separately ensiled. The method mainly comprises the following steps of: (1) harvesting the chicory and the ensiled corn; (2) cutting ensiled corn stalks to the length of 1.5 to 2.5 centimeters, and cutting the chicory to the length of 3.0 to 5.0 centimeters; (3) mixing the chicory and the ensiled corn uniformly in a weight ratio of (1-3): (4-8) when the water content of each of the chicory and the ensiled corn is 60 to 75 percent; (4) adding themixture into an ensiling container, compacting and sealing; and (5) fermenting at the temperature of between 20 and 30 DEG C, and thus finishing ensiling. The invention has the advantages that any additive is not required, the ensiling equipment is simple, and the method is environment-friendly, convenient to operate and the like.
