Description

Technical Field

[0001] The invention belongs to the technical field of trace element water-soluble fertilizers, and particularly relates to a trace element water-soluble fertilizer for kiwi fruit. Background Art

[0002] Kiwifruit (Actinidia) is widely planted in my country, mainly in two types: Chinese kiwifruit (Actinidia.chinensis) and delicious kiwifruit (Actinidia..deliciosa). Both types of kiwifruit are characterized by luxuriant branches and leaves, extremely large branch growth, and extremely strong growth potential. It is difficult to stop the growth of branches even if the branches are pinched many times; the tree bears many fruits early, and rarely drops fruits. In terms of fertilizer requirements, it has the following characteristics. Kiwifruit has an urgent need for nutrients. If inorganic nutrients are lacking in a short period of time, it will show yellowing, small leaves, and stop growing. The root system of kiwifruit is sensitive to soil salt concentration, and fertilizers should not be used excessively or too concentratedly. Kiwifruit absorbs much more nutrients than ordinary fruit trees. Its annual requirement for nitrogen, phosphorus, and potassium is 1.5-2 times that of other fruit trees such as apples and peaches. In addition to nitrogen, phosphorus, and potassium, kiwifruit also requires abundant calcium, magnesium, manganese, zinc, iron, chlorine, and other trace elements. And the requirement for trace elements is greater than that of ordinary fruit trees. For example, the demand for chlorine is much greater than that of general crops. The general demand for chlorine is 0.025%, while that of kiwifruit is as high as 0.8%-2%, especially when the potassium content is insufficient. The critical value of effective iron in the soil is 11.9 mg / kg, which is also much higher than that of other fruit trees. Kiwifruit needs more iron, zinc, boron, manganese, copper and other elements for growth and development, but the water-soluble fertilizers currently sold on the market cannot fully contain the above-mentioned trace elements or the content of trace elements is too low, or the composition ratio is not completely targeted at the absorption characteristics of kiwifruit for trace elements, and the composition ratio of each trace element is unreasonable. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a trace element water-soluble fertilizer for kiwi fruit in view of the deficiencies of the above-mentioned prior art. The trace element water-soluble fertilizer for kiwi fruit has relatively comprehensive nutrient elements and can effectively solve the problems of yellowing, small leaves, abnormal leaf color, etc. caused by nutrient deficiency in kiwi fruit production.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a water-soluble trace element fertilizer for kiwi fruit, the water-soluble trace element fertilizer for kiwi fruit is composed of a group A raw material and a group B raw material in a mass ratio of 1:0.5;

[0005] The raw materials of group A are composed of Bacillus subtilis powder, Bacillus amyloliquefaciens powder and Trichoderma harzianum powder in a mass ratio of 1:0.5:0.5;

[0006] The raw materials of group B are composed of iron fertilizer, manganese fertilizer, boron fertilizer, zinc fertilizer and copper fertilizer in a mass ratio of 10:5:3:1.5:0.5;

[0007] Preferably, the iron fertilizer is composed of the following raw materials in mass fractions: 30% to 40% EDDHA-Fe, 20% to 40% HBED-Fe, and the balance is IDHA-Fe.

[0008] Preferably, the manganese fertilizer is a mixture of two of IDHA-Mn, DTPA-Mn and EDDHA-Mn.

[0009] Preferably, the boron fertilizer is boric acid.

[0010] Preferably, the zinc fertilizer is a mixture of two of IDHA-Zn, DTPA-Zn and EDDHA-Zn.

[0011] Preferably, the copper fertilizer is a mixture of two of IDHA-Cu, DTPA-Cu and EDDHA-Cu.

[0012] The method of using the trace element water-soluble fertilizer for kiwifruit in the present invention can be root irrigation, drip irrigation or foliar spraying.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The kiwifruit trace element water-soluble fertilizer of the present invention has relatively comprehensive nutrient elements, and can effectively solve the problems of yellowing, small leaves, abnormal leaf color, etc. caused by nutrient deficiency in kiwifruit production. It can be sprayed on the leaves or irrigated at the roots. It has certain preventive and therapeutic effects on leaf diseases and root diseases. Root irrigation can significantly promote root growth, strengthen tree vigor, and improve leaf photosynthetic efficiency. Compared with traditional EDTA chelating agents, the environmentally friendly chelating agent is adopted, and the biological toxicity is low.
