- Abstract:
- In order to make it clear that how about the contributed level of the water and fertilizer is，and how about the best dosage of nutrient is under the highest yield of apple.The apple orchards of Xingtai county was regarded as the research object，and evaluating its level of the input of water and fertilizer by the investigate about the form and dosage of nutrient，the mode and dosage of irrigation，besides exploring the best dosage of nutrient under the highest yield based on the mode of boundary line.The result showed that，the dosage of inorganic fertilizer was high，but the organic fertilizer was short，the average of dosage of inorganic fertilizer N，P2O5，K2O were 825 kg·hm-2，460 kg·hm-2，692 kg·hm-2 respectively，but the organic fertilizer N，P2O5，K2O were 177 kg·hm-2，138 kg·hm-2,100 kg·hm-2.The percentage of organic fertilizer was low，which was 2735%，besides the species was miscellaneous，the proportion of chicken manure，sheep dung and commodity organic fertilizer 9561%，and the main mode of irrigation was traditional irrigation and furrow irrigation whose percentage was 9370%，drop irrigation was 630%;the main frequency was 3-4 in the growing season of apple，compared to drop irrigation，the dosage of each time irrigation more than 140%，100%.The analysis of the mode of Boundary line showed that under the highest yield of apple the best dosage of nutrient was 61650 kg·hm-2，37190 kg·hm-2，55310 kg·hm-2respectively，the percentage of the contribution to the yield were 2800%，1760%，2260% respectively.In a word，in Xingtai，the dosage of nutrient was high，and it was partial to inorganic fertilizer，the kind of fertilizer was miscellaneous.The main mode of irrigation was traditional irrigation and furrow irrigation,the waste of water was serious.
