Therefore, the present invention provides following method scheme：
In a first aspect, the present invention provides a kind of corn planting method, comprise the following steps：Site preparation processing：With selecting nonirrigated farmland
Block applies base fertilizer to planting site afterwards and carries out overlay film as planting site, and in carrying out site preparation ridging before sowing；Wherein, site preparation
When ploughing depth be 25cm~30cm；Sowing：Selection corn variety is sowed, and the spacing in the rows between holding is adjacent two plants is
28cm~33cm, depth of planting is 3cm~5cm；Draw seedling final singling：Sow after 10d~15d, break ground and draw seedling；Treat seedling length to 3~4
Final singling is carried out during leaf, tiller is removed afterwards；Field management：Deinsectization, weeding and processing of topdressing are carried out to planting site；Wherein, chase after
Fertilizer is included in the jointing stage successively and the typhon mouthful phase is carried out；Harvest：Corn is harvested in the harvest season.Certainly, it is of the invention
Corn can also carry out harvest in proper late；There is corn kernel evening to receive volume increase phenomenon, and the morning and evening of harvest time is to yield and quality
Influence it is very big.The ripe outside appearance of corn is that bract discoloration is loose, and seed is hardened, and cortex light, seed connects with cob
Section part there is black layer, this just indicates that corn has been enter into full ripe stage, can now harvest.If greenery are very well, corn should
Appropriate evening receives, so that the nutrient remained in stalk continues to convey into seed, increases grain weight, and the season of growth allows to postpone 5 again~
7d is harvested, and can improve yield more than 5%.If in order to catch up with kind of a second stubble crop, harvested in wax ripeness latter stage band stalk, whole strain is stacked, than
Direct crop and quality will be better at that time.
