Study On The Application Of Yellow Mealworm Excrement In Flower Planting.

In this exam,I choose choisy,zinnia,cosmos,rhododendron simsii planch,rose chinensis Jacq as the experimental materials.By the pot test,the yellow mealworm excrement was mixed with soil according to the ratio of 0,2%,4%,6% and 8%.To study the effect of different proportion of added yellow mealworm excrement on the growth and development of herbaceous flowers,woody flowers and vine flowers.This test is expected to provide a theoretical basis for the exploitation and utilization of Tenebrio molitor Linnaeus,the feasibility of applying Tenebrio molitor Linnaeus as the organic fertilizer for flower cultivation and an appropriate adding ratio.The main results of the experiment are as follows:(1)After analysising the test result,it shows that Yellow mealworm excrement has a clear improvement on totoal N,total P,total K,organic matter in soil.The test shows that total N of yellow mealworm excrement is 41.6g/kg which exceeds garden soil 670.37%,total P is 0.2g/kg which exceeds garden soil 100%,total K is 9.3g/kg which exceeds garden soil 1228.57% and organic matter is 81.84g/kg which exceeds garden soil 280.65%.There is a significant increase in the content of soil organic matter and N、P、K after adding yellow mealworm excrement,which shows Tenebrio molitor Linnaeus is a kind of high quality and efficient bio-organic fertilizer.(2)It can promote the cultivation of Zinnia elegans Jacq,Cosmos bipinnata Cav,Rhododendron simsii Planch and Rosa chinensis Jacq when the added yellow mealworm excrement ratio is 2%,including high leaf chlorophy II,amount of plant growth,aboveground growth index,root energy.But there is a low ergence rate when the concentration is 4% and 6%.These four flowers would die when the yellow mealworm excrement concentration is 8%.(3)It can promote the growth and development of Pharbitis nil(L.)Choisy when the added yellow mealworm excrement ratio was 2%,4% and 6%,especially when the ratio is 4% which has the best effct on the growth of Pharbitis nil(L.)Choisy,including high leaf chlorophy II,amount of plant growth,aboveground growth index,root energy.But when the proportion is 8%,it would inhibit the growth of Pharbitis nil(L.)Choisy.The test shows that Tenebrio molitor Linnaeus can be used as the flower seedling fertilizer,and applied into flower cultivation widely.
