Embodiment Construction

[0049] A control method of flat hazel dodder, comprising the steps of:

[0050] 1. Deep plow the ground outside the hazel tree in autumn and winter, with a depth of 5-8cm. At the same time, the severely damaged parts of dodder and hazel were manually removed.

[0051] 2. Appropriate thinning or thinning of over-dense hazelnut clusters to improve ventilation and ventilation conditions.

[0052] 3. From April to late May, spray 200-400 times 200-400 times of 48% dimethamine (butaline) emulsifiable concentrate three times.

[0053] 4. From late May to mid-June, spray 10% glyphosate 40-600 times liquid + (0.3%-0.5%) ammonium sulfate, 1.5% glyphosate water + (0.3%-0.5%) ammonium sulfate.

[0054] 5. Apply Zhenfeng No. Ⅲ reagent (the main component is plant ash) or 1.5% sodium pentachlorophenate + 2% prophyllide solution 400-600 times at each stage before July.

Abstract

The invention provides a control method for corylus heterophylla fisch dodder. The control method comprises the following steps that (1) the land outside corylus heterophylla fisch are ploughed depth in autumn, and the ploughing depth ranges from 5 cm to 8 cm, and dodder and the severely damaged portions of the corylus heterophylla fisch are removed manually; (2) thinning or intermediate felling is conducted on a corylus heterophylla fisch clump which is too dense so that the ventilation condition can be improved; (3) from April to late May, 200-fold to 400-fold 48% dibutalin (butralin) emulsifiable concentrate is sprayed three times; (4) from late May to mid June, a mixture of 40-fold to 600-fold 10% glyphosate and (0.3%-0.5%) ammonium sulfate and a mixture of 1.5% gyphosate solution and (0.3%-0.5%) ammonium sulfate are sprayed; (5) during each stage before July, a Zhenfeng Number three agent (the main ingredient is plant ash) is applied or a mixture of 1.5% sodium pentachlorophenate and 400-fold to 600-fold 2% prometryn liquid is applied. By the adoption of the control method, the quality of corylus heterophylla fisch products can be greatly improved; the method has the advantages of being efficient, safe, economical and the like.

Description

technical field [0001] The invention relates to a method for preventing and treating plant diseases of twining vine-like hemiparasitic grasses, in particular to a method for preventing and treating Cuscuta flat hazel. Background technique [0002] Flat hazel (Corylus heterophylla Fisch) is a plant of the genus Corylus in the family Corylaceae. It is an important economic forest tree species in northern my country. Its dried fruit is edible and it is also a woody oil plant. Its comprehensive utilization value is extremely high. Its nuts are rich in nutrition, rich in 18 kinds of amino acids such as tryptophan and lysine, and multivitamins, which are very beneficial to human health. Its branches, leaves, bark and husk contain paclitaxel, which can be used to treat cancer after extraction. The root system of the flat hazel is developed, cold-resistant, and barren-resistant. It is an excellent pioneer tree species for water and soil conservation and soil improvement, and its in...
