Auxiliary fertilizer capable of single-dose applying sand grape in Xinjiang and application method

Abstract

The invention discloses an auxiliary fertilizer capable of single-dose applying sand grape in Xinjiang and an application method. The application method is suitable to more than five tree-ages of sand grape in a vineyard with medium or lower sand management, the distance of fertilizer application and grape trunk is 50-70cm, the fertilizer application depth is 20-40cm, and the prepared auxiliary fertilizer contains pure N:P:K being 1:0.7:0.9; the auxiliary fertilizer is prepared by the following raw materials according to the weight percentage: 50-60 of organic fertilizer particles, 28-35 of ordinary superphosphate, and 12-15 of lemery; the auxiliary fertilizer is packaged by brown paper, and each bag contains 280-290g; the place 50-70cm away from the grape trunk before sprouting after thegrape comes up out of land in spring is ditched or dug a pit the depth of which is 40cm, and then 15000kg of goat manure is applied in each mu primarily, 1 bag of auxiliary fertilizer is applied on the goat manure per square meter later, 8 cloverleaf type holes with 3mm diameter are tied at the upper layer of the bag of the auxiliary fertilizer by iron wires, and soil is buried for watering. The invention has simple and easy operation and remarkable effect, and can save the production cost.

Description

technical field [0001] The invention belongs to the technical field of fertilization of fruit trees, relates to an auxiliary fertilizer for grapes in sandy land, in particular to an auxiliary fertilizer for one-time fertilization of grapes in sandy land in Xinjiang and a fertilization method, and the method is especially suitable for fertilization of sandy land grape gardens in Turpan, Xinjiang , Fertilization is only carried out once a year, which can meet the annual growth and fruiting needs of grapes. Background technique [0002] Grape is the third largest cultivated fruit tree species in the world, and it is also one of the main cultivated fruit trees in my country. Grape fruit has beautiful shape and color, sweet and sour taste, rich nutritional value and high medical value. With its unique geographical environment and climate resources, Xinjiang produces excellent quality grapes and is one of the main grape producing areas in my country. However, as the soil-forming...

Problems solved by technology

However, as the soil-forming parent material in Xinjiang is mainly composed of a variety of rocks, the calcium carbonate content in the soil is 5% to 10%, resulting in an alkaline soil with a pH value between 7.5 and 8.5, and most of the vineyards in Xinjiang are managed at a moderate level. Fertilization in sandy soil and saline-alkali soil in vineyards is likely to cause fertilizer fixation and loss, and the fertilizer utilization rate is low. Often due to inappropriate fertilization ratios and methods, the effect of fertilization is not obvious or fertilization in the early stage is not effective in the later stage. Defertilization affects the yield and quality of grapes
