Abstract
The present invention relates to a pesticide for controlling mustard disease. Said pesticide composition includes (by wt%) 15-70% of calcium cyanamide and 10-75% of calcium oxide, and the rest is impurity. Said invention also provides its application method and concrete steps.
Description
Technical field
The present invention relates to a kind of agricultural chemicals, particularly a kind of agricultural chemicals and the using method thereof that can prevent and treat stemmustard disease.
Background technology
Fuling hot pickled mustard tube is the non-staple food treasure of China, with the pickles of the sauerkraut in Europe, Japan and be described as the world's three your name's salted vegetables.Its raw material crop tumorous stem mustard in Fuling cultivated area above 2.33 ten thousand hectares, middle nineteen nineties in last century is since the Cruciferae club root is found in the hot pickled mustard tube field of the north of the Changjiang River, Fuling, hundred victorys, increase the weight of year by year, hectare surplus onset area reaches 4000 at present, the development of serious threat hot pickled mustard tube industry, by studies show that of scientific research personnel, club root is to be caused by the Cruciferae pathogen plasmodiophora, at present effective agricultural chemicals that club root also is not suitable for.
Summary of the invention
The purpose of this invention is to provide a kind of harmful germ and the sick worm that can effectively kill in the hot pickled mustard tube planting soil, particularly can kill the Cruciferae pathogen plasmodiophora that causes the hot pickled mustard tube club root, the effectively generation of control hot pickled mustard tube club root, the while can be improved the using method of agricultural chemicals and this agricultural chemicals thereof of hot pickled mustard tube quality.
For achieving the above object, the technical scheme that is adopted is: a kind of agricultural chemicals of preventing and treating stemmustard disease, it is characterized in that this agricultural chemicals contain nitrolim that percentage by weight is 15-70% and 10-75% calcium oxide all the other be impurity.Above-mentioned agricultural chemicals is powdery or graininess.
The using method of the agricultural chemicals of above-mentioned control stemmustard disease, it uses step to be:
(1) in the arable land, evenly spreads fertilizer over the fields above-mentioned agricultural chemicals 20 1 120kg/ mus; (2) pour water in the arable land after spreading fertilizer over the fields agricultural chemicals, make soil moisture remain on 60-85%; (3) the above-mentioned ground that spreads fertilizer over the fields agricultural chemicals is ploughed, the degree of depth of ploughing deeply is 0-40cm; (4) placed 7-30 days in the arable land after will pouring water.
Above-mentioned placement 7-30 days is with the arable land covering with plastic film after pouring water, and with tight with grave around the mulch film, airtight placement was removed mulch film airing 1-2 days after 15-28 days.Also can be with the arable land covering with plastic film, with tight with grave around the mulch film, airtight placement be removed mulch film airing 1-2 days after 15-28 days after pouring water under the film.
Have following characteristics by a large amount of evidence the present invention:
1, can effectively kill the Cruciferae pathogen plasmodiophora that causes the hot pickled mustard tube club root, effectively prevent and treat and reduce the generation of stemmustard disease insect pest;
2, easy to use.Situation according to diverse geographic location and arable land, directly spread fertilizer over the fields the agricultural chemicals that a certain amount of the technical program provides, after carry out simple routine operation, just can be implemented in the generation of interior effective control of hot pickled mustard tube planting area and the insect pest of reduction stemmustard disease, need not to process once more and prepare, provide a kind of effective use simple agricultural chemicals during for peasant's use;
3, the agricultural chemicals that provides of the technical program can not cause the problem of land deterioration after long-term the use, and can suppress nitration reaction for nitrogen required in the hot pickled mustard tube process of growth and the plain nutrition of calcium, improves nitrogen utilization efficiency;
4, behind the agricultural chemicals that the use the technical program provides in the hot pickled mustard tube planting site, weeds in field is had the obvious suppression effect, to improving the content of calcium in the hot pickled mustard tube, the content of nitrate and nitrite significantly acts in the reduction hot pickled mustard tube simultaneously.

For being adapted under the soil condition of different regions, uses in this agricultural chemicals, agricultural chemicals can be made the graininess of the dressing form of forming by Bao Xin and the outer housing of Bao Xin, Bao Xin is formed by nitrolim and calcium oxide Different Weight percent concentration proportioning, the outer housing of Bao Xin is made up of binding agent and agricultural nitric acid rare earth or chemical fertilizer, the proportion relation of binding agent and agricultural nitric acid rare earth or chemical fertilizer can be any proportioning, but must guarantee the coating and shaping of graininess agricultural chemicals.
In the above-described embodiments, the purpose of ploughing deeply is that agricultural chemicals is fully contacted with soil, and the degree of depth of ploughing is relevant with local concrete condition, and the serious area of disease is ploughed should be dark, and the light area of disease is ploughed can be more shallow.The purpose of placing is to use medicine that the adequate time reaction is arranged, and is beneficial to soil disinfection.Length and the temperature of standing time are inversely proportional to, and when temperature is higher than 38 ℃, place more than 7 days, when temperature during at 28-38 ℃, place about 7-20 days, when temperature is lower than 28 ℃, place 20-30 days, plant hot pickled mustard tube then.The peritonaeum sealing can reduce standing time, makes the effectiveness of agricultural chemicals reach best.The time of peritonaeum sealing also is to regulate according to the height of temperature, and when temperature was higher than 38 ℃, sealing was more than 7 days, when temperature during at 28-38 ℃, seals about 10 days, when temperature is lower than 28 ℃, places about 20 days.
According to the regional situation of applying pesticides, when using this agricultural chemicals, use various straws, can effectively improve soil soil fertility and organic matter, highly beneficial to the growth of each plant species.
