Effects of soil conditioners on lettuce production and soil nutrients
In order to explore the effects of soil conditioner on lettuce production and soil nutrients,the yield,plant height,plant width and number of leaves(commercial vegetables)were measured by adding 4 soil conditioners to lettuce,such as Fudu No.1,Tukangjian No.1 and Tukangjian No.2,and preliminatively the soil conditioner suitable for this area was screened.The results showed that lettuce treated with Tukangjian No.2 and potassium humate from mineral sources increased yield by 2.60%and 3.66%respectively compared to CK(without conditioning agent);The plant height and width treated with potassium humate from mineral sources increased by 1.01%and 1.04%respectively compared to CK,four conditioners could increase the number of lettuce leaves,chlorophyll content,nitrogen content,and leaf surface humidity,with T1 treatment having a stronger promoting effect;The vitamin C and protein content of the leaves treated with Tukangjian No.1 increased by 30.23%and 12.26%compared to CK,respectively,while the potassium humate treatment from mineral sources increased by 29.46%and 10.38%compared to CK;The soil pH,available potassium,and available phosphorus content treated with potassium humate from mineral sources increased by 2.18%,0.73%,and 3.77%,respectively,compared to CK.In summary,treatment with potassium humate from mineral sources could promote increased yield of lettuce leaves,improve vitamin C,protein content,and chlorophyll content.At the same time,it had a certain of improvement effect on soil pH,available potassium,and available phosphorus content.It had a good comprehensive promotion effect in soil conditioning and lettuce production and could be promoted and applied locally.
