Description
Technical Field
The invention relates to the technical field of citrus seedling culture, in particular to a citrus seedling culture method.
Background
Citrus belongs to Rutaceae genus plant. The nature likes warm and humid climate, and the cold resistance is slightly stronger than that of pomelo, lime and sweet orange. China is one of the important origin places of citrus, is a world-wide citrus producing country, and has more than 4000 years of cultivation history. The citrus resources in China are rich, the excellent varieties are various, and the citrus industry is the agricultural support industry in China and plays an extremely important role in agricultural economy.
The conventional citrus seedling propagation method mainly comprises the following steps: grafting, cuttage, seedling, layering and the like. The citrus is mainly grafted, and the grafting can not only keep the excellent properties of a scion variety, but also utilize the favorable characteristics of the stock to achieve the purposes of early fruiting, and enhancing the cold resistance, drought resistance, disease and pest resistance and the like.
In the prior art, during the citrus seedling raising process, the root system of the bred citrus seedlings is often rotten, so that the transplanting survival rate of the citrus seedlings is low, the normal production of the citrus seedlings at the later stage is influenced, and the fruit bearing of citrus trees is further influenced.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a citrus seedling method, which solves the root rot phenomenon of citrus in the seedling process and improves the transplanting survival rate of citrus seedlings after outplanting.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a citrus seedling raising method comprises the following steps: (1) sowing stock seeds; (2) transplanting stock seedlings; (3) grafting; (4) managing the grafted seedlings; (5) detecting and outplanting;
before the stock seeds in the step (1) are sowed, the stock seeds are soaked in a disinfectant, and then are washed clean, wherein the disinfectant consists of an oxidant, quicklime, jatropha curcas seed oil and water; the concentration of the oxidant in the disinfectant is 0.5-1%, the concentration of the quicklime is 10-20%, and the content of jatropha curcas seed oil is 5-15 g/L; the oxidant is potassium permanganate or sodium hypochlorite; and (3) when the stock seedlings in the step (2) are transplanted, soaking the roots of the stocks in the disinfectant, draining and then transplanting.
Preferably, before the rootstock seeds in the step (1) are sown, the rootstock seeds are soaked in the disinfectant for 10-30 min.
Preferably, when the stock seedlings are transplanted in the step (2), the root of the stock seedlings is soaked in the disinfectant for 5-15 min.
Preferably, the stock seedling transplanting in the step (2) is seedling lifting and transplanting when the thickness of the stock is 2-4mm and the plant height is 20-30 cm.
Preferably, the grafting in the step (3) is carried out by using the scion when the thickness of the stock to be transplanted is 4-15mm and the plant height is 50-60 cm.
Preferably, the step (4) of seedling management after grafting refers to the operations of bending stocks, removing sprouts for multiple times, cutting off protogenic stocks and daily water and fertilizer management of the stock seedlings after grafting.
The invention is characterized in that the disinfectant is used, and the disinfectant consists of an oxidant, quicklime, jatropha curcas seed oil and water; the concentration of the oxidant in the disinfectant is 0.5-1%, the concentration of the quicklime is 10-20%, and the content of the jatropha curcas seed oil is 5-15 g/L; the oxidant is potassium permanganate, sodium hypochlorite or hydrogen peroxide solution; the oxidant and the quicklime have certain sterilization effect, so that the decay of the root system of the citrus can be relieved to a certain extent; but production practices show that the phenomenon of rotting of the root system of the citrus seedlings cannot be completely avoided by using the single oxidant quicklime or the compound consisting of the oxidant and the quicklime.
The invention provides the first time for preventing and treating the seedling root rot by using the jatropha curcas seed oil, and the jatropha curcas seed oil contains chemical components such as toxalbumin, ketones, hydrocyanic acid, ligustrazine and the like to prevent and treat the citrus root rot, thereby achieving unexpected effects. The disinfectant liquid consisting of the oxidant, the quicklime, the jatropha curcas seed oil and the water has good prevention and treatment effect on root rot phenomenon in the seedling raising process of citrus seedlings.
The invention is also characterized in that in the citrus seedling raising process, two disinfectant disinfection operations are carried out, one is directed at the stock seeds, and the other is directed at the root of the stock seedlings after cultivation; the two disinfection operations radically solve the root rot phenomenon of the citrus seedlings in the seedling process.
Compared with the prior art, the invention has the beneficial effects that:
when citrus seedling raising operation is carried out, on one hand, stock seeds are disinfected by disinfectant before the stock seeds are sown; on the other hand, before transplanting the cultured stock seedlings, the roots of the stock seedlings are soaked in the disinfectant for disinfection; through two times of disinfection operation, the root system rot phenomenon of the citrus seedlings in the seedling raising process is solved from the root source, the transplanting survival rate of the citrus seedlings after outplanting is effectively improved, and the citrus seedlings prepared by the cultivation method are thick and strong in plants and developed in root systems, and are transplanted and grow rapidly after the citrus seedlings are outplanted.
