Synergistic Effect Of Compost And Compost Tea

In order to further explore how to make better use of compost and compost tea,to provide theoretical basis for the application of compost and compost tea in vegetable production,we study on the effect of different compost and compost tea on soil nutrients change in the cultivation of Chinese cabbage,study on the changes of enzyme activities of chinese cabbage,qualities in harvest time,study on the different amount of compost and compost tea on tomato fruit qualities,as well as the application of compost leaching residue in tagetespatula cultivation.The main results are as follows:1 Different compost could significantly improve the soil nutrient content.The chicken manure compost(A3)was the most effective in raising the total nitrogen and effective phosphorus in the soil.The straw compost(A5)was the most effective in increasing soil efficiency potassium and organic matter.It can significantly improve the content of total nitrogen and available potassium in soil by watering the compost tea.Application of compost and compost tea can improve cabbage enzyme activity.Compared with chemical fertilizer compost could reduce the nitrate content of Chinese cabbage,straw compost best,irrigation compost tea can reduce the nitrate content of Chinese cabbage.Different compost affect plant weight did not at the same dialogue menu,A4 weight of 2.92 kg was significantly higher than other treatments.Irrigation compost tea could improve cabbage plant weight than CK plant weight increased by 16.74%.2 Composting treatment could increase the soluble sugar content,increase the content of VC,improve tomato lycopene content,improve tomato mouth feel,ang could reduce the nitrate content in fruit.Excessive application of compost could increase the nitrate content in fruit,4kg/m~2 is the best compost amount effect.3 Watering compost tea could significantly increase soluble sugar,lycopene content,VC content in fruit,improve tomato taste,reduce the nitrate content in fruit.The compost tea water quantity is 2kg/m~2 to improve the quality of tomato fruit was most significant.4 The addition of compost residue in the soil would significantly reduced the soil bulk density,and the soil and compost residue volume ratio of 1: 2(D2)was reduced by 100% compared with soil(CK).The contents of total N,available P and available K in soil were significantly increased compared with CK,and the effect of D2 was the most significant,followed by soil and compost leaching residue volume ratio of 1: 1(D1).The addition of composting residue to the soil increased the potassium accumulation in the upper part of the peacock grassland,and the volume ratio of soil to compost extraction was 2: 1(D3).The addition of composting residue in the soil can significantly increase the flowering rate of the Tagetes patula,the ratio of soil and composting residue to 2: 1 was the best effect,but the addition of excess compost to remove the residue would reduced the amount of flowering.
