Embodiment 1

[0027] Special fertilizer described in the present embodiment, configure 1000 kilograms of special fertilizers, with 130 kilograms of ammonium chloride, 80 kilograms of superphosphate, 40 kilograms of potassium sulfate, 420 kilograms of sulfur, 80 kilograms of clay, 90 kilograms of ferrous sulfate, 50 kilograms of magnesium sulfate , 45 kg of zinc sulfate, 15 kg of manganese sulfate, crushed and stirred evenly, diluted to 100 kg with 50 kg of 85% concentrated phosphoric acid, evenly sprayed into the fertilizer, and the water content is controlled at 3-6%. If it exceeds the standard, it can be taken Sun dry or tumble dry.

[0028] The obtained fertilizer can be applied directly, or can be mixed with organic fertilizer and applied together. The application method is hole application or furrow application. According to the diameter of the forest tree, 50-70% of the radius within the orthographic projection of the tree crown is dug or dug, and the depth is 10-15 cm. Every 10 cm DB...

Embodiment 2

[0030] The preparation process is the same as in Example 1, except that the ratio of the components of the special fertilizer is 160 kilograms of ammonium chloride, 90 kilograms of superphosphate, 42 kilograms of potassium sulfate, 400 kilograms of sulfur, 86 kilograms of pottery clay, 83 kilograms of ferrous sulfate, and 83 kilograms of magnesium sulfate. 38 kg, 42 kg of zinc sulfate, and 12 kg of manganese sulfate are mixed, pulverized and stirred evenly, diluted to 92 kg with 47 kg of 85% concentrated phosphoric acid, and evenly sprayed into the fertilizer.

Embodiment 3

[0032] The preparation process is the same as in Example 1, except that the proportion of the components of the special fertilizer is 190 kilograms of ammonium chloride, 100 kilograms of superphosphate, 44 kilograms of potassium sulfate, 380 kilograms of sulfur, 84 kilograms of pottery clay, 72 kilograms of ferrous sulfate, and 72 kilograms of magnesium sulfate. 36 kg, 40 kg of zinc sulfate, and 11 kg of manganese sulfate are mixed, crushed and stirred evenly, then diluted to 86 kg with 43 kg of 85% concentrated phosphoric acid, and evenly sprayed into the fertilizer.

Abstract

The invention discloses a special fertilizer for preventing and controlling forest iron-deficiency yellows and an application method thereof. The special fertilizer comprises the following components: 25 to 66.9 percent of composite inorganic nitrogen-phosphorus-potassium fertilizer, 26.6 to 55 percent of acidic material and 6.5 to 20 percent of trace element fertilizer. The application method comprises the following steps of: (1) annularly ditching or digging holes with the depth of 10 to 15 centimeters on the 50 to 70 percent of radius part in crown orthographic projection according to forest diameter at breast height (DBH), uniformly spreading 400 to 500 grams of special fertilizer every 10-centimeter DBH, and covering soil after applying the fertilizer; and (2) applying the fertilizer once by repeating the step (1) in early spring, late summer and early autumn every year for 1 to 2 years continuously. A preventing and treating method has the advantages that: the fertilizer is convenient to apply and easy to popularize. The special fertilizer provided by the invention has the advantages of improving rhizosphere soil, reducing the pH value of the rhizosphere soil and improving the activity of trace elements, such as iron and the like, in soil so as to control the yellows completely.

Description

technical field [0001] The invention relates to the field of prevention and control of tree diseases and insect pests, in particular to a special fertilizer for preventing and treating iron-deficiency yellowing disease of trees and an application method thereof. Background technique [0002] Iron is one of the essential trace elements for plant growth. The trace elements represented by iron have a great influence on the synthesis of chlorophyll. When lacking, plants will show yellowing of leaves. Iron-deficiency chlorosis of forest trees is a common plant deficiency disease in alkaline soils. It occurs widely in my country. Plants in Northwest, North, East, and Southwest regions generally occur, especially fruit trees and acid-loving flowers and trees. The root cause of iron-deficiency yellowing of forest trees is that under alkaline soil conditions, the activity of trace elements such as iron is greatly reduced, and the root system cannot absorb it, which affects the synthe...
