Garlic continuous-cropping disease control method

Abstract

The invention discloses a garlic continuous-cropping disease control method. The method comprises the following steps: (1) mixing seed garlic cloves with a seed dressing agent tebuconazole before plantation; (2) applying a potassium sulfate compound fertilizer and a microbial fertilizer as a base fertilizer; (3) carrying out after manuring: spraying a rooting, seedling strengthening and freeze preventing plant growth regulator and a nutrient agent when 4-5 true leaves of garlic appear after the seedling emergence of the garlic; (4) carrying out spring management: carrying out chemical control 5-6 times from mid-March to early May, wherein a medicine used in primary chemical control comprises a zinc thiazole solution, an azoxystrobin solution, a difenoconazole solution, Dadexi and Hejiahuan; (5) irrigating rich water two times; (6 ) carrying out late management after garlic sprout pulling: spraying a medicine comprising the zinc thiazole solution, brassin-gibberellin, brassinolide and the Hejiahuan in a foliage manner. The method adopting organic combined application of a variety of fertilizers and pesticides effectively controls continuous cropping harms and various diseases and insect pests of garlic, obviously increases the yield and improves the quality of the garlic.

Description

technical field [0001] The invention relates to a method for preventing and treating garlic heavy cropping disease, and belongs to the technical field of agricultural planting. Background technique [0002] Garlic (Garlic) is also called garlic, garlic head, garlic, gourd, single garlic, single head garlic, is the general designation of garlic plants.

Problems solved by technology

[0005] At present, the main diseases of garlic are as follows: the garlic turns green slowly from the middle to late March, the garlic stems are thin and not thick, the dry tips are yellow and the leaves are thin and narrow, and the three and four leaves at the bottom also start to turn yellow gradually. Garlic grows slowly, and the control effect of chemical fungicides and foliar nutrients is not obvious

In April, as the temperature rises, the yellowing and dry tips of garlic leaves are more serious. After watering around Qingming, the premature aging of garlic is accelerated. Some plots die first, and the garlic has no new roots and has turned yellow and lifeless. In a short period of time, it will cause continuous death, resulting in small garlic moss, small garlic heads and low yield in the later stage.
