Study On High-yielding Cultivation Techniques Of Hongyu 236

Hongyu 236 is a seed variety which Jilin Hongye seed Limited Company tested through regional experiments in 2016.It needs 130 days to become mature from emergence in spring in the northeast China with compact plants.To explore the biggest yield potential of Hongyu 236 and find out the most optimal cultivation procedures,the test has taken the planting density,application rates of nitrogen fertilizer,phosphate fertilizer and potash fertilizer as variables,made a comprehensive analysis on soluble protein of maize plants in tasseling period,the accumulation of soluble sugar and maize seeds,and finally got the best density in medium ripening spring-sowing area and the most suitable project for nitrogen,potash and phosphate fertilizer.The results are as follows:1: Maize planting density is the biggest factor that influences the accumulation of soluble sugar,soluble protein and target yield in tasseling period,followed by the application rates of nitrogen fertilizer,phosphate fertilizer and potash fertilizer.When these factors range from-1-1,soluble sugar and protein reach the highest level;at-2-0,they increase with higher index;at 1-2 they decrease with higher index.These factors influences each other.For example,the density and nitrogen have the greatest impact for each other.Next comes the density and fertilizer,which shows that a proper increased amount of maize planting density and fertilizer plays a vital role in yield growth.2: When the planting density is at 74080-77500 strain/ hm2,apply N for 312.8-334.61kg/hm2,P2O5 95.45-104.55kg/hm2,K2O5 109.65-112.75kg/hm2,and there will be a possibility of more than 95 % that soluble sugar can accumulate over 0.83ug/mg.3: When the planting density is at 76427-78887.5 strain/ hm2,apply N for 334.4-352.85kg/hm2,P2O5 104.975-114.175kg/hm2,K2O5 109.425-118.225kg/hm2,and there will be a possibility of more than 95 % that soluble protein can accumulate over 26.27ug/mg.4: The best model for corn yield: the experiment is set in the middle part of Jilin province,and the best planting density is 78514-81383.25 strain/hm2,and apply N for 331.51-352.51kg/hm2,P2O5 101.796-112.404kg/hm2,K2O5 111.894-122.91kg/hm2.Then the soluble protein and sugar of corn in tasseling period can be very high which makes it possible to achieve a high yield.This experiment aims to find a most suitable plan for Hongyu 236 and analyze these factors which influence yield.This will help find out and promote the highest and most effective scheme for the plant.
