Application Effect of Different Sulfur and Chlorine Containing Slow-Release Blended Fertilizers in Peanuts
Slow-release fertilizers,as a new type of fertilizer,have a promising development prospect.Sulfur and chlorine are essential nutrients for peanuts,but there have been few reports on the effects of different types of slow-release fertilizers containing sulfur or chlorine on peanut yield and growth conditions.In 2023,our study conducted a fertilizer efficiency trial of sulfur and chlorine-containing slow-release fertilizers on peanuts to explore their effects on peanut agronomic traits,yield,and quality.The peanut variety used in the experiment was'Weihua 24',four treatments were set up:sulfur-containing common fertilizer 15-10-20S(T1),sulfur-containing slow-release blended fertilizer 15-10-20S(T2),chlorine-containing common fertilizer 15-10-20Cl(T3),and sulfur-chlorine-containing slow-release blended fertilizer 15-10-20SCl(T4).The results showed that compared with T1,T2 significantly increased the average single kernel weight,number of pods per plant,yield,and economic benefits of peanuts,with a 5.4%increase in yield and a 7.6%increase in income;it also significantly increased the content of soluble sugar,and trace elements in peanut seeds.Compared with T3,T1,T2 and T4 significantly increased the number of pods per plant,average fruit weight,yield,and economic benefits of peanuts;T2 and T4 significantly increased the fat content in peanut seeds.
