AI Technical Summary

Problems solved by technology

Drip irrigation pipelines are not fully utilized, not only cannot fully meet the nutrient needs of bananas, but also increase the cost of fertilization and labor costs
The main reason is that there is currently a lack of a fertilizer formulation and fertilization method for the macro, medium and micronutrient nutrients required for bananas to be applied by drip irrigation

Embodiment 1

[0029] The drip irrigation and fertilization test of bananas is as follows:

[0030]From 1 to 3 months after the banana seedlings are planted, mix 33.5kg of urea, 12.3kg of diammonium hydrogen phosphate, 22.5kg of potassium chloride, and 1.2kg of boric acid per hectare, add 100-150L of water to dissolve and make fertilizer solution A, called dihydrate Dissolve 19.3kg of calcium chloride in 50L of water to make fertilizer solution B, and add 26.4kg of magnesium sulfate heptahydrate to dissolve in 50L of water to make fertilizer solution C. The three types of fertilizer solutions A, B and C are applied separately. Flush the fertilizer tank and pipes with water. Fertilize once every 11 to 13 days on average, and apply fertilizer 5 times in total.

[0031] From 4 to 6 months after the banana seedlings are planted, mix 33.5kg of urea, 12.3kg of diammonium hydrogen phosphate, 37.5kg of potassium chloride, and 1.2kg of boric acid per hectare each time, add 100-150L of water to disso...

Embodiment 2

[0036] The drip irrigation and fertilization test of bananas is as follows:

[0037] From 1 to 3 months after the banana seedlings are planted, mix 53.6kg of urea, 20.8kg of diammonium hydrogen phosphate, 36.0kg of potassium chloride, and 2.0kg of boric acid per hectare each time, add 100-150L of water to dissolve and make fertilizer solution A, called dihydrate Dissolve 25.7kg of calcium chloride in 50L of water to make fertilizer solution B, and add 35.0kg of magnesium sulfate heptahydrate to dissolve in 50L of water to make fertilizer solution C. The three types of fertilizer solutions A, B and C are applied separately. Flush the fertilizer tank and pipes with water. Fertilize once every 11 to 13 days on average, and apply fertilizer 5 times in total.

[0038] From 4 to 6 months after the banana seedlings are planted, mix 59.6kg of urea, 23.1kg of diammonium hydrogen phosphate, 66.7kg of potassium chloride, and 2.2kg of boric acid per hectare each time, add 100-150L of wat...

Embodiment 3

[0043] The drip irrigation and fertilization test of bananas is as follows:

[0044] From 1 to 3 months after the banana seedlings are planted, mix 54.4kg of urea, 17.8kg of diammonium hydrogen phosphate, 35.6kg of potassium chloride, and 2kg of boric acid per hectare, add 100-150L of water to dissolve and make fertilizer solution A, called dihydrate chlorine Calcium 28.6kg is dissolved in 50L of water to make fertilizer solution B, and 39.3kg of magnesium sulfate heptahydrate is dissolved in 50L of water to make fertilizer solution C. The three types of fertilizer solutions A, B and C are applied separately, and water must be used after applying each type of fertilizer solution Flush the fertilizer tanks and pipes. Fertilize once every 11 to 13 days on average, and apply fertilizer 4 times in total.

[0045] From 4 to 6 months after the banana seedlings are planted, mix 39.5kg of urea, 12.9kg of diammonium hydrogen phosphate, 43.2kg of potassium chloride, and 1.5kg of boric ...

Abstract

The invention discloses a method for applying fertilizer for banana through drop irrigation, comprising the following steps: applying the fertilizer in different stages according to the fertilizer need characteristic of the banana; preparing different kinds of fertilizer liquids according to the property and use quantity of the selected fertilizer; and respectively conveying the fertilizer liquids to the range of the root system of the banana through a drop irrigation system so as to meet the nutrient needed by the good growth of the banana, such as nitrogen, phosphorus, potassium, calcium, magnesium, boron and sulfur. The invention adopts the drop irrigation system to convey the large, middle and small quantity of trace element nutrient. The method has strong operability, cannot block the drop irrigation pipeline and dropping nozzles, and can prolong the service time of the drop irrigation pipeline. The invention saves 14%-47% of the nitrogen, 49%-60% of the phosphorus and 13%-46% ofthe potassium, and improves 14%-23% of production volume. Net benefit in per hectare is over 14000 Yuan, the anti-disease ability is improved, and the quality of the banana is improved.

Description

technical field [0001] The invention relates to the technical field of orchard irrigation and fertilization, in particular to a banana drip irrigation and fertilization method. Background technique [0002] Fertigation technology is an irrigation and fertilization technology system established by combining the two basic elements of crop growth and development, "water" and "nutrient". Drip fertilization is the main method. Because of its advantages of water saving, fertilizer saving, labor saving, high yield, high quality, high efficiency, and environmental protection, it has become an important part of modern agricultural technology and is widely used in agricultural production in developed countries. Compared with conventional fertilization methods, the fertigation system has the following advantages: (1) Improve the utilization rate of fertilizer; (2) Save a lot of labor required for fertilization; (3) It can be flexibly, conveniently and accurately controlled according t...
