Effect of Fertilizer Reduction and Spraying of New Fertilizer on the Yield and Quality of Orah

Abstract

To effectively solve the Orah production cost is higher, fruit sales price is low, and the poor economic benefit and growth regulator fruit easy to peel rough, appearance quality affected, in Guangxi Guilin with orange stock Orah as the object, carried out the fertilizer, organic fertilizer reduction and spray, shower tianrun series products of Orah yield and quality influence test. The results show that, according to the orange peptide organic fertilizer, compound fertilizer, soil conditioner and urea fertilizer amount of 25%, 50% or 100% fertilizer of the three treatments of the best comprehensive effect, can significantly improve the tree growth quantity and fruit quality of Orah, effectively increase the yield of Orah; lack of regularity in the influence of soil nutrient content from 0 to 20 cm, most of the nutrient content is in the range of high amount or excessive amount; according to the fertilizer amount of 25%~100% fertilizer and spray, shower day moisturizing series of fertilizer, no significant differences in nitrogen and magnesium content, the differences in the content of phosphorus, potassium, iron, zinc, manganese and boron did not show a significant decrease with the decrease of the soil ditch fertilizer, there was no significant increase due to the spraying of Tianrun series leaf fertilizer, however, the content of zinc and manganese was significantly higher than the control (CK); the highest number of results and plant yield of Orah fertilized by 50% of the fertilizer amount, it has the obvious effect of yield stimulation; 25%~100% of the fertilizer amount, the required water fertilizer and foliar fertilizer all according to the test design spray, shower Tianrun series products, significantly increased the titratable acid and soluble solid content, fruits has a stronger flavor and a better taste, fruit quality was significantly improved, however, the differences in single fruit weight, edible rate and vitamin C content lacked consistency between the two years.
