Problems solved by technology

In 2000, the area of ​​apples had reached 400,000 mu, but the management and production level of apples was still relatively low
Traditional fertilization methods make the amount of fertilizer applied inaccurate, so that the quality and yield of apples cannot be improved

Embodiment Construction

[0015] A method for precise fertilization of apples, characterized in that the method comprises the following steps:

[0016] (1) On the basis of applying 4000 kg of high-quality organic fertilizer per mu, determine the target yield according to the nutrient content in the soil, that is, soil fertility, and determine the amount of chemical fertilizer applied according to the fertility required for the target yield, soil fertilizer supply capacity and chemical fertilizer utilization rate; chemical fertilizer The formula for calculating the amount of fertilizer is: fertilizer amount (kg / mu) = (total amount of nutrients required for target yield - soil fertilizer supply) / (nutrient content in fertilizer × fertilizer utilization rate);

[0017] (2) The basal fertilizer is mainly organic fertilizer, combined with the application of chemical fertilizer, the organic fertilizer should be fully applied, the amount of organic fertilizer applied is 4000 kg per mu, nitrogen fertilizer and...

Abstract

The invention relates to a method for accurate fertilization for apple tree. The method decides target yield according to soil fertility based on 4000 kg of high quality organic fertilizer, then determine fertilizer consumption according needed fertilizer, fertilizer supply ability by soil and fertilizer availability, dressing all organic fertilizer, 70% of the nitrogen fertilizer and phosphatic fertilizer and 50% of potassium fertilizer as base fertilizer, taking left fertilizer for additional dressing, dressing the left 30% nitrogen before germination, dressing the left 30% phosphatic fertilizer before flower bud differentiation, dressing left potassium fertilizer during fruit expanding period, spraying fertilizer on leaf in different growing period for 6- 8 times in one year. The productivity and output value are increased by 21.5% and 21.3% respectively, the high- quality fruit rate is increased from 35% to 62%,and the net value is added by 615 yuan per mu.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a method for precise fertilization of apples. Background technique [0002] Luochuan is one of the best apple eugenic areas in the world, a national demonstration county for apple industrialization construction and a national pollution-free apple export demonstration base county. In 2000, the apple area had reached 400,000 mu, but the management and production level of apples was still relatively low. One of the most important reasons is that the soil nutrient content in the county's orchards is low, the fertilization technology cannot meet the standardized requirements, and the amount of fertilizer application is inaccurate. Apple export and development of international high-end market. [0003] In terms of apple fertilization technology, my country is still in the research and exploration stage, and is gradually improving the relevant standards of apple fertil...
