Abstract

The invention provides a high concentration drip irrigation special fertilizer for the vegetative growth phase of grapes. The fertilizer comprises the following main components in part by weight: 244 to 267 parts of potassium nitrate, 181 to 198 parts of monoammonium phosphate, 357 to 390 parts of urea, 139 to 209 parts of magnesium sulfate heptahydrate, 0.3 to 0.6 part of boric acid, 3.6 to 5.8 parts of EDTA chelated iron, 0.2 to 0.4 part of EDTA chelated copper, 0.6 to 1.0 part of EDTA chelated manganese, 0.002 to 0.004 part of sodium molybdate, and 1.0 to 1.6 parts of EDTA chelated zinc. The special fertilizer is especially designed for a drip irrigation system, and is suitable for the requirement on each element at the vegetative growth phase of the grapes. The special fertilizer can obviously improve the photosynthesis of plants and the nutrient substance accumulation amount of leaves, establishes a firm substance foundation for quick inflation of fruits and fruit growth in later period, and has the effect better than that with only the application of a base fertilizer or only the application of a straight fertilizer so as to achieve the aims of reducing fertilizer and improving effect. Currently, the country widely popularizes drip irrigation technology and fertilizer reducing and effect improving technology, and the fertilizer plays a role in reducing fertilizer and improving effect in a grape drip irrigation system and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and is a special fertilizer for high-concentration drip irrigation, which is especially suitable for the vegetative growth period from after grape germination to grape fruit expansion. Background technique [0002] Grape (Vitis vinifera L.) is one of the four largest fruit trees in the world. Humans have cultivated grapes for thousands of years. According to statistics, the world's grape cultivation area is about 10 million hectares, with a total output of 60 million tons, accounting for 1 / 4 of the world's total fruit output. As the number of grapes consumed at home and abroad is increasing, the economic value of grapes is also increasing, and it has become the first choice for farmers in the vast rural areas of our country, especially in southern provinces, to get rid of poverty and become rich. At the same time, with the country's continuous increase in investment in farmland infrastructur...
