Abstract
The present invention discloses a spray type method for rapidly producing detoxified small potatoes by soilless culture with high efficiency. The method can effectively improve the yield of detoxified small potatoes. The present invention is characterized in that MS nutrient liquid is prepared from the principal raw material of ammonium nitrate, potassium nitrate, potassium dihydrogen phosphate, magnesium sulfate, potassium iodide, sodium molybdate, cupric sulfate, cobalt chloridem manganese sulphate, zinc sulphate, orthoboric acid, ferrous sulfate heptahydrate, complexon and calcium chloride; the nutrient liquid is sprayed in the different growth periods of plants by an intermittent method, and high-yield seed potatoes are obtained by matching other management methods for producing detoxified small potatoes.
Description
Technical field
The present invention relates to a kind of agricultural production method, especially promote the new method of crop growth, volume increase.
Background technology
Potato stem tip detoxification has been widely used in agricultural production at present, potentiality from potato individual plant knot potato number, conventional production method has only been excavated 1/10th of its production capacity, and individual plant knot potato quantity and yield per unit area height are that toxicity micro potato is bred one of problem of most critical.Soilless culture production small de-poisoned patato is the technology of a widespread usage in detoxification stock breeding under greenhouse, the solarium's condition, but existing nutrient solution and production method can't realize the small de-poisoned patato high yield.
Summary of the invention
In order to improve unit are knot potato quantity, the invention provides the method that a kind of atomizing does not have autochthonal product small de-poisoned patato, its nutrient solution and advanced cultivation management by spraying scientific formula can be realized the high and stable yields of small de-poisoned patato.
The technical solution adopted for the present invention to solve the technical problems mainly is by a kind of MS nutrient solution of following formulated, and sprays in the potato seedling.
The MS prescription

Form part with above-mentioned four and mix respectively, first three groups is dissolved in earlier in the water, and again with the 4th group of adding, constant volume is that pH value is 500 liters of MS nutrient solutions between the 5.5-6.5 at last.
More than in four groups of chemical analysis, every kind of component content can be adjusted respectively according to the different times of plant growing.
The MS nutrient management, the hardening phase utilizes the basic nutrition liquid of 1/2 concentration to supply with plant strain growth after the field planting, grows new root after 5-7 days and changes basic nutrition liquid, helps the growth of overground part plant.After field planting 30-40 days, change the nutrient solution (nutrient solution composition ratio is adjusted) that promotes that stem tuber forms and grows.Solution temperature remained between 20-22 ℃, all more renewed nutrient solution every 20 days.Beginning period of growth was every spraying in 3 minutes 30 seconds in the reproductive process; Fertility was sprayed 30 seconds every 5 minutes mid-term; Late growth stage was every spraying in 30 minutes 1 minute.
Embodiment
Used MS nutrient solution composition and scheme are described identical in the implementation process, only at different times the composition ratio are adjusted to some extent.
1. MS nutrient management: the hardening phase utilizes the basic nutrition liquid of 1/2 concentration to supply with plant strain growth after the field planting, grow new root after 5-7 days and change basic nutrition liquid, help the growth of overground part plant, after field planting 30-40 days, change the nutrient solution (realizing) that promotes stem tuber to form and grow by adjusting nutrient solution composition ratio.Solution temperature remained between 20-22 ℃, all more renewed nutrient solution every 20 days.
2. temperature treatment: regulate temperature according to growthdevelopmental stage, keep 20-23 ℃ in the nutrition production phase, the stem tuber formation stage keeps 23-26 ℃.
3. pH value management: remain between the 5.5-6.5 at the whole growing pH value, utilize HCI or NaOH to adjust.
4. spraying management: beginning period of growth was every spraying in 3 minutes 30 seconds; Mid-term was every spraying in 5 minutes 30 seconds; Later stage was every spraying in 30 minutes 1 minute.
5. the extermination of disease and insect pest: spray weekly that Rogor and 800 times of liquid metalaxyl-mn-zns are prevented eliminating aphis, early blight and late blight.
6. management at sunshine: fertility keeps the long-day more than 13 hours to handle in early stage, begins short-day after field planting 30-40 days and handles.
When potato tubers reaches 5 grams when above, scale off with cutter, dry under scattered light, greening handled for 2 weeks.Potato seed after the greening is stored in the cellar for storing things, and storage temperature is 2-6 ℃, humidity 70-80%.Adopt said method to cultivate the production small de-poisoned patato and can increase substantially output.
