A method for repairing magnesium deficiency in zaoxiangyou

Abstract

A method for repairing magnesium deficiency in Zaoxiang pomelo, comprising the following steps: Step 1: one-time basal application before the germination of Zaoxiang pomelo, the basal application includes ternary compound fertilizer and magnesium-containing fertilizer; Step 2: collection of leaf samples and content determination, Collect leaf samples and measure the chlorophyll content and element content of the leaf samples; Step 3: collect fruit samples and measure their quality, collect fruit samples to measure their total sugar content, soluble solids content, total acid content, Vc content, juice yield and Food rate; Step 4: Data denoising; Step 5: Fertilizer supplementation. According to the measured element content and fruit quality data, determine whether the magnesium content has reached an appropriate value, and determine whether magnesium fertilizer needs to be supplemented. The advantage is that it can effectively correct the yellowing of leaves caused by magnesium deficiency, the fall of old leaves in winter, and the small fruit; and it can increase the magnesium content of pomelo trees. And significantly improve the single fruit weight, yield and quality of Zaoxiang pomelo, and put forward the suitable magnesium fertilizer types and the combined application technology of magnesium fertilizer and medium and micronutrient elements.

Description

Technical field[0001]The present invention belongs to the field of agricultural fertilization, and in particular, the present invention relates to a method of magnesium that of early fragrant pomelo.Background technique[0002]Yongjia early incense is a local name of the 1980s. It is one of my country's excellent pomelo varieties by the Zhejiang Cry maturity variety. The early fragrant pomelo orchard mainly established in the mountainous and hilly area, the soil conditions, the mineral nutrient, too much nitrogen, phosphorus, potassium chemical fertilizer and reduce organic fertilizer usage, plus the addition of trace mineral elements in the management of tree nutrient management , Induce early fragrant orchard, magnesium. It is mainly manifested in old leafhuang, and irregular macular spots on both sides of the main pulse. The green zone of the leaffriend is usually pouring V-type, and the old leaves of the winter (especially those with many branches or plants) have fallen, and the f...

Problems solved by technology

The magnesium needed for plant growth mainly comes from the soil. Affected by factors such as high temperature, rainy and strong soil acidity, the magnesium in the soil is easily leached and lost, resulting in a decrease in the yield and quality of tobacco leaves, cabbage, and citrus.
