The invention discloses a green quality-improving and efficiency-increasing off-ground cultivation method for producing potato breeder seeds, which belongs to the technical field of off-ground cultivation of the potato breeder seeds and comprises the following steps: the cultivation method comprises the steps of building a cultivation room, building a seedbed, paving a matrix, controlling temperature and humidity, broadcasting base fertilizer, watering before transplanting, transplanting virus-free seedlings, managing in an early stage, managing in a middle stage and managing in a later stage.
Description
Technical Field
The invention belongs to the field of off-ground cultivation technology of potato breeder seeds, and particularly relates to a green quality-improving and efficiency-improving off-ground cultivation method for producing potato breeder seeds.
Background
The production of potato stock is the most important link of the virus-free seed potato production technical system, mainly uses culture medium vermiculite to transplant virus-free test-tube plantlets, and is a production method generally applied in northern potato main production areas at present. Gansu province is an important commercial potato and seed potato production area of Chinese potatoes, and through development for many years, a predominant production area with distinct characteristics and clear regional layout and the largest virus-free seed potato production base in China are formed. The Dingxi is the main potato production area in Gansu province, the first national grade regional fine variety breeding base in China, and a standardized production technology system for the virus-free potato seeds is established.
The potato stock culture mostly adopts the traditional half-off cultivation, namely, a layer of isolation gauze is paved on soil, matrix vermiculite is paved on the gauze, and virus-free seedling transplantation is carried out on the vermiculite, so that the potato stock is produced. However, with the increasing of the cultivation period, the traditional half-off cultivation does not completely separate the potatoes from the continuous cropping soil, the root systems of the potatoes can contact the soil from the gaps of the gauze to absorb germs, so that the soil-borne diseases such as potato scab and black nevus frequently occur, the continuous cropping obstacles are increasingly prominent, and the quality of the original seeds is seriously affected.
At present, a steel-structure rolling seedbed and a simple off-ground cultivation device are gradually applied to the production of potato breeder seeds, but the corresponding cultivation technology is incomplete in matching, the temperature and humidity control and the supply system research of nutrient elements are less in the cultivation process, and the application of the technology is seriously hindered.
Disclosure of Invention
The invention aims to provide a green quality-improving and efficiency-improving off-ground cultivation method for producing potato breeder seeds on the basis of a traditional cultivation mode in a semiarid region, aiming at the problems that soil-borne diseases are increasingly serious, the application amount of pesticides and fertilizers is large, the application is not economical and reasonable and the like in the production of the potato breeder seeds.
In order to achieve the purpose, the invention adopts the technical scheme that:
a green quality-improving and efficiency-increasing ground-off cultivation method for producing potato breeder seeds comprises the following steps:
s1: building a culture room: constructing a cultivation room for producing potato breeder seeds, and arranging a shed film, an insect-proof gauze, a sunshade net, a ventilation opening, a reservoir and a sprinkling irrigation system;
s2: setting up a seedbed: setting up a seedbed in a cultivation room, paving black plastic ground cloth on the seedbed, and scattering a small amount of carbendazim at the bottom of the seedbed for disinfection after paving the black plastic ground cloth;
s3: laying a matrix: the matrix is vermiculite, and is 1 bag/m2Standard paving (about 10 kg), wherein the paving thickness is about 8 cm;
s4: temperature and humidity control: controlling the temperature of the cultivation room to be 14-28 ℃, controlling the humidity to be 20-50%, and keeping the water content of the seedbed matrix to be 10-50%;
s5: base fertilizer broadcasting: weighing compound fertilizers and organic fertilizers according to the area of the seedbeds in proportion, uniformly mixing the weighed compound fertilizers and organic fertilizers, and uniformly spreading the mixture on vermiculite of each seedbed;
s6: watering before transplanting: opening a sunshade net in the cultivation room before planting, watering by using a water pipe (without a spray head) one day before transplanting to ensure that the water content of the seedbed matrix reaches 80 percent, and watering until the seedbed drips;
s7: transplanting the detoxified seedlings: before transplanting, stirring vermiculite by a bamboo stick, scraping the vermiculite by a scraper, then sweeping the vermiculite by a broom, marking a line spacing by a scriber, determining a plant spacing according to density, then transplanting detoxified seedlings, spraying water by a water pipe (with a spray head) again after the transplanting is finished, ensuring that water is uniformly and thoroughly poured, and keeping warm and moisturizing the detoxified seedlings after the transplanting is finished;
s8: early management: in the early stage of transplanting the detoxified seedlings, opening an air vent of a cultivation room for ventilation and cooling in spring and summer when the morning is 10:00 to 16:00 afternoon, replenishing water according to the humidity condition of a seedbed after seedling planting to ensure that the water content is uniformly and thoroughly poured, reducing ventilation time according to the temperature and humidity condition of the seedbed in cloudy days, pressing the detoxified seedlings after transplanting for 15-20 days, wherein the step of pressing the seedlings is to press the upper parts of the seedlings into vermiculite to promote the seedlings to grow from lateral branches and roots, replenishing vermiculite in a place with thin vermiculite, replenishing water and fertilizer in time after pressing the seedlings, spraying 1-2 kg of compound fertilizer with good solubility through a water and fertilizer integrated system to promote the rooting, retracting a sunshade net after 30-40 days of transplanting the detoxified seedlings to fully receive illumination, and spraying a small amount of bactericide and insecticide;
s9: and (4) medium-term management: watering in time according to the humidity of a seedbed in the middle stage of transplanting the virus-free seedlings, and topdressing according to the growth and development stage of the virus-free seedlings, wherein the fertilizer follows a small amount of multiple principles in the topdressing process;
s10: and (4) post management: and in the later stage of transplanting the detoxified seedlings, reducing the watering amount according to the humidity of the seedbed, opening a sunshade net for cooling when the temperature is higher, stopping watering 20 days before potato harvesting, harvesting when vermiculite is dried and loosened, drying for 5-7 days (without the sun) after harvesting, grading, bagging and warehousing.
In step S1, the cultivation room may be constructed as a sunlight greenhouse or a net room.
In the step S5, the compound fertilizer and the organic fertilizer are weighed according to the area of the seedbed, and the area of the seedbed is 10m2Selecting and using a sprinkling rich compound fertilizer (N: P)2O5:K215 percent of O and 15 percent of C) about 0.6kg, when the O is replaced by other compound fertilizers, the content needs to be converted, the nitrogen content can not exceed the limit, the use of urea is not advocated, 0.5 to 1kg of organic fertilizer under the condition of Jiatianxia (containing organic matter 40 percent) is selected, and potash magnesium sulfate fertilizer (containing K) is selected2More than or equal to 24 percent of O and more than or equal to 6 percent of Mg) of 0.15kg, uniformly mixing the weighed scattered rich compound fertilizer, the organic fertilizer under the first day and the potash magnesium sulphate fertilizer, and then spreading the mixture on vermiculite of a seedbed to ensure uniformity, otherwise, the growth vigor of the detoxified seedlings is not uniform.
