Specific embodiment

With reference to specific embodiment, the present invention is described in detail.

Embodiment 1

1st, the spring sowing summer harvest (the 1st batch)：

Selection Henan ensiling 23, Yayu No.8, northern agriculture ensiling 208,777 4 Silage Maize varieties of Chinese list, in March, 2016 Sow within 17th, wide-and narrow-row sowing, wide row 80cm, narrow row 40cm after planting promote seedling using Biodegradable mulch covering and heat insulating, emerge Per hectare stays 6.75 ten thousand plants of seedling afterwards, per 1 plant of cave；Emerge within after planting 7 days or so, male full heading time, June 20 are taken out before and after May 20 Harvesting, the 95 days time of infertility (because of growth prometaphase continuous low temperature Rainy sparse sunlight, breeding time substantially postpones).

2nd, summer sowing autumn harvest (the 2nd batch)：

Selection Henan ensiling 23, Yayu No.8, northern agriculture ensiling 208,777 4 Silage Maize varieties of Chinese list, in June, 2016 The artificial no-tillage seeding of stubble is connect within 22nd, wide-and narrow-row is sowed, wide row 80cm, narrow row 40cm, and per hectare stays 7.5 ten thousand plants of seedling after emerging, often 1 plant of cave；

Emerge within after planting 5 days or so, August takes out male full heading time before and after 5 days, September is gathered on the 6th, the 76 days time of infertility.Illustrate 6 Month 15-25 day summer sowing silage corn, September 5-10 day can be with ripe results.

3rd, autumn sowing winter receipts (the 3rd batch)：
