Abstract

The invention provides a prevention and treatment method of tomato bacterial wilt. A Bordeaux mixture formula and an application method of the invention are utilized so that the tomato bacterial wilt can be effectively prevented from occurring; the development of the bacterial wilt can be effectively controlled and treated at the beginning of the tomato bacterial wilt, so that the prevention and treatment method is one of the effective methods for planting tomatoes in bacterial wilt high-prevalence areas in south of China.

Description

A kind of anti-therapy of bacterial wilt of tomato

Technical field

The present invention is a kind of prevention and treatment method of bacterial wilt of tomato, relates to bacterial wilt hotspot Commercial Growers, specifically bacterial wilt prevention and methods for the treatment of in a kind of tomato production practice.

Background technology

At the most of tomato in greenhouse growing area of China; humidity is larger; ventilative poor, in commercial tomato production process there is dead highland barley in bacterial wilt large area, once fall ill; cannot effect a radical cure; contagiosity is extremely strong, is easy to cause total crop failure or drop in production over a large area, and causes Hunan, Hubei, Jiangxi San Sheng tomato planting area day by day to reduce; and the season of May Hunan, the listing of Jiangxi tomato just, now China May, whole nation tomato was in short supply.This patent, through testing for many years, utilizes limewash to fill with root, and the agricultural lotus mycin spray leaf in leaf portion not only effectively can prevent the generation of bacterial wilt, can also treat at the initial stage of a disease.The tomato production district occurred frequently to bacterial wilt is significant.

Summary of the invention

In order to the soil-borne disease bacterial wilt solving south China Duo Di tomato production district is occurred frequently, and once fall ill and cannot treat, in high temperature, the high Humid Area of rainy water, spread speed is quite fast, often in two or three days cause dropping in production over a large area or having no harvest, in production, once peasant household of falling ill all must lift seedlings, lime sterilization.If can develop a kind of low price and can effective control of plant bacterial wilt method, to Hunan, Hubei etc., bacterial wilt hotspot is significant.The province such as Hunan, Jiangxi eats tomato district raw and can locally in a large number produce, and decreases cost, significant to farmer richness.

The technical solution adopted for the present invention to solve the technical problems is: its technology comprises following step: the limewash of (1) preparation 400 times, as far as possible now with the current, gets supernatant for subsequent use; (2) fill with root, every strain 100ml, 20 days one time by with the limewash previously prepared in 3 days-15 days after planting seedling, connect filling 3 times; (3) at the beginning of morbidity, remove top dehydration part, in time with the 800 times of liquid sprayings of agricultural streptomycin sulphate 3000 times of liquid+potassium dihydrogen phosphates, 5-10 days once, connects spray 2-3 times.

The invention has the beneficial effects as follows: bacterial wilt of tomato can be prevented to fall ill and treat the plant of bacterial wilt of tomato their early stage; An effective way is provided for solving bacterial wilt harm Central China area tomato planting, tomato can be planted in a large number for Central China Vegetable produce district and provide technical support, for a change Hunan mainly relies on outside tomato to fall to provide technical guarantee for a long time, owing to decreasing defeated expense far away, price is also fallen thereupon, can reduce civic living cost; Also can increase the income of vegetable grower simultaneously, transfer the enthusiasm of peasant planting tomato.

Embodiment

1,1. white lime is produced, and takes quicklime lump, waters limit with water, until whole stone powders (quicklime stone directly can not be dropped in water).2. prepare the limewash of 400 times, white lime is water-soluble, and 2 minutes precipitations, get supernatant for subsequent use.3. fill with root, every strain 100ml with the limewash prepared, premorbid starts to fill with root for 20 days, and filled with once every 20 days, booth is double, continuous three times of open country.4. as found morbidity strain, removing dehydration top, strengthening irrigation quantity, outer sulfuring up acid strepto-.

2, enhancement of field management adopts rational application of fertilizers, carries out high bedding cultivation, receives 3000-6000 times of liquid+potassium dihydrogen phosphate 600-800 times liquid according to growth of cereal crop seedlings growing way every spray in about 10 days IDALL, if the young plant excessive growth spray special short Feng Ling of vegetables 500-1000 times of liquid.Their early stage opens mulch film loose ground in time, and hydrofuge is breathed freely, and the earth's surface Bai Houzai that dries in the air puts down mulch film and covers tightly.

(2) case study on implementation and analysis

Embodiment 1

Select the plot that morbidity is heavy, continuous cropping is planted, and finding that there is plant part at the initial stage of a disease has existing picture different agents of wilting to fill with root,

Table 1: experimental period is transplanted in booth on February 15th, 2012, spraying time is respectively on March 1st, 2012 and on March 20th, 2012, place: Zhangjiajie, each experiment 100 strain, in triplicate, experiment contrast kind Sha dragon (Academy of Agricultural Sciences researches and develops by Qingdao)

Note: various Pesticide use amount is all undertaken by packing instruction, limewash 400 times, contrasts the tomato for not executing any drug treating, and within 30 days, namely survival rate counts 30 days from cultivation seedling, within 90 days, is also count from cultivation seedling.

Embodiment 2

Table 2: variable concentrations, difference are joined limewash filling root effect (survival rate %) experiment contrast kind Sha's dragon (Academy of Agricultural Sciences researches and develops by Qingdao) experimental period and transplanted in booth on February 15th, 2013, spraying time is respectively on March 5th, 2013 and on March 25th, 2013, place: Yongding District, Zhangjiajie)

Note: 1: contrast the tomato for not executing any drug treating;

2: formula one, two, three, four is lime respectively: water=1:100,400,600;

3: timing statistics is 60 days (namely tomato fruit look starts colour-change period) after planting seedling;

4: filling a prescription two from the experimental results, to execute secondary limewash effect best.

Embodiment 3

Table 3: open country fills with root number of times to the impact of tomato survival rate, experiment contrast kind Sha dragon (Academy of Agricultural Sciences researches and develops by Qingdao) experimental period is transplanted in booth on February 15th, 2014, spraying time is respectively on March 5th, 2014, on March 25th, 2014, on April 15th, 2014, place: Yongding District, Zhangjiajie)
