Embodiment 1
[0028] Corn variety: Qingnong 105;
[0029] Experimental base: Gansu Minle river beach saline-alkali land, soil pH 8.7;
[0030] Sowing date: April 16, harvest date September 22;
[0031] Preparation of cow manure: Take fresh cow manure and ferment and decompose naturally, then dry it to remove moisture.
[0032] Step 1. Preparation of arable land soil improver: mix 38 parts of peanut shells, 35 parts of bean stalk powder, 25 parts of cottonseed shells, and 58 parts of cow dung;
[0033] Step 2, plowing the land: after Jerusalem artichoke crop rotation, spread the soil improver prepared in step 1 evenly at 450Kg / mu, and plow 30-40cm deep;
[0034] Step 3. Seed pretreatment: Soak corn seeds with chlormequat for 6 hours, and then immerse at 35°C by sodium alginate: chitin: redispersible latex powder: water: 6:2:10:100 parts by mass In the proportioned suspension, take it out and immerse it in water below 4°C for 10 seconds, then take out the corn seeds, drain the water and dr...
