Description

Method for promoting growth and development of eggplant and preventing and treating verticillium wilt
Technical Field
The invention relates to a method for promoting the growth and development of eggplants and preventing and treating verticillium wilt.
Background
Eggplant (Solanum melongena L.) is a plant of Solanum of Solanaceae, has developed root system, is relatively favored by fertilizer and fertilizer, and is widely cultivated in China [ Liu Fu, Liangyong, Chen Yu Hui, Chang Jia new variety Chang za No. 8 breeding [ J ]. Chinese vegetables, 2016(12):53-55 ]. Eggplant verticillium wilt, also called as margined crazy and black heart disease, is a soil-borne vascular bundle disease and is one of the main diseases damaging eggplant production. The verticillium wilt of eggplants is a disease which is caused by verticillium dahliae infection and occurs on the eggplants, is one of main diseases in the production of the eggplants in a sunlight greenhouse, has great harm to the production of the eggplants, and often causes dead harvest or seed destruction when the disease is serious. Since Carpenter first reported greensickness in 1914, the disease has spread to more than 30 countries and regions around the world [ epilithic rock, causes of cotton greensickness outbreak and disaster control measures [ J ] plant protection, 1994,20(1):34-35 ]. Eggplant verticillium wilt occurs commonly and is seriously damaged in north China, and the yield and the quality of the eggplant are reduced [ Jing Li Jun, frequent billings, Sujiu, preliminary research on inheritance of eggplant verticillium wilt [ J ]. gardening academy, 2000,27(4): 293-. Because the verticillium wilt of eggplants is a soil-borne disease, the prevention and treatment effect of the pesticide is poor, the breeding is difficult, and the grafting method and the technology are difficult.
The biological organic fertilizer has the functions of fertilizing soil fertility, enhancing plant resistance and the like. Research on treatment of eggplants with bio-organic fertilizer has been reported, and the influence of different concentrations of liquid bio-organic fertilizer on the growth of eggplant seedlings by wangi [ wangi, liuxianning, sun guan ]. jilin vegetables, 2017(07):38-39] et al show that the plant height and stem thickness of eggplants treated with bio-organic fertilizer are significantly higher than those of controls, and significantly increased by 32.88% and 26.52% respectively than those of controls. Experimental studies of Wangsheng (Wangsheng, the influence of applying different organic fertilizers on the yield and the quality of continuous cropping eggplants [ J ] agricultural engineering, 2020,10(10): 105-.
Zhao founding, pharmacodynamic tests of different medicaments for preventing and treating the verticillium wilt of eggplants [ J ] experiments of farmers for causing rich, 2017(24), 103 and other experimental studies show that 300 times of solution of 1% shenqinmycin suspension has the best effect of root irrigation, and the prevention and treatment effect on the verticillium wilt of the eggplants is 73.6%. Tests of Dongdong Kun (Dongdong Kun, eggplant Verticillium wilt prevention and treatment effect test (J), modern rural science and technology, 2018(12), 66 and the like show that the prevention and treatment effect of 10 percent of double-effect liquid 200 times liquid and 15 percent of wilting prevention ecological liquid 300 times liquid on eggplant Verticillium wilt reaches 88.2 to 91.6 percent; tests of different pesticides of the royal jelly chrysanthemum [ royal jelly chrysanthemum, Zhuhua, Guojinping ] for controlling the verticillium wilt of eggplants [ J ] Shanghai vegetables, 2010(1):61-62 ] and the like show that the control effect of 800 times liquid of 70% mancozeb wettable powder and 800 times liquid of 70% thiophanate-methyl wettable powder on the verticillium wilt of the eggplants reaches 78%. The former people all use chemical pesticide to prevent and cure verticillium wilt of eggplants, and the research of using biological organic fertilizer to prevent and cure verticillium wilt of eggplants is rarely reported.

The plant height, stem thickness and maximum leaf area are measured by a graduated scale and a vernier caliper respectively. The plant height is the height from the root and stem boundary of the eggplant to a growth point measured by a graduated scale, the stem thickness is the stem thickness of the first node of the stem base measured by a vernier caliper, the maximum leaf area is the length and width of the maximum leaf of the plant measured by the graduated scale, and then the product of the length and the width is calculated. The number of the leaves of a single plant is one leaf with the diameter of more than or equal to 5 cm.
1.3.2 fruit development indices
1.3.2.1 index of fruit nutritive quality
The method mainly measures the content of vitamin C, the content of protein, the content of soluble sugar and the content of organic acid, and adopts a 2, 6-dichlorophenol indophenol titration method, an ultraviolet absorption method, an anthrone colorimetric method and a standard alkali solution titration method respectively. Soluble solids were measured using a digital display glucometer.
1.3.2.2 index of commercial quality of fruit
The diameter of the stem, the diameter of the fruit, the length of the fruit and the length of the stem are measured by a vernier caliper, a curve ruler and a straight ruler respectively. The diameter of the stem is the most uniform diameter of the stem of the eggplant, the diameter of the fruit is the diameter of the uniform part in the middle of the eggplant, the length of the fruit is the length of the whole eggplant, and the length of the stem of the fruit is the length of the stem of the eggplant, wherein the diameter of the stem is measured by a vernier caliper. The single fruit weight is measured by an electronic balance and is equal to the ratio of the weight to the number.
1.3.3 onset index of Verticillium wilt
1.3.3.1 grading standard of disease index of verticillium wilt
Level 0: no symptoms are caused;
level 1: slight scab exists;
and 2, stage: the lesion spots occupy less than 1/4 of the whole leaf area;
and 3, level: the scab occupies 1/4-1/2 of the whole leaf area;
4, level: the lesion occupies more than 1/2 of the whole leaf area.
1.3.3.2 index for disease resistance of verticillium wilt
Field incidence (%) ═ number of diseased plants/number of total investigated plants × 100%;
the disease index ═ Σ (number of disease-grade plants × number of disease-grade)/(total number of survey plants × highest disease-grade value) × 100;
the prevention and treatment effect is (treatment disease index-control disease index)/control disease index multiplied by 100%.
