Description
Technical Field
The invention belongs to the technical field of konjak propagation, and relates to a propagation method of a sweet konjak seed.
Background
Konjak is a general name of Amorphophallus Blume of Araceae (Araceae), which is called Konjac or konjaku in ancient times, and its english name Elephantfoot yam or Elephantfoot faro, which is now commonly represented by the most widely planted Amorphophallus Konjac (Konjac). The konjak planted and applied in China is mainly Konjac and white konjak containing glucomannan, which must be processed to be edible, whereas sweet Konjac (Amorphophalus sp. Groff) belongs to starch type Konjac, whose bulb is yellow, which usually grows 4 ~ 10 leaves, which can be directly eaten as vegetable, can be boiled, fried, etc., and can also be eaten fresh, and has excellent taste, and mainly in Yunnan, the propagation of Konjac can be carried out by sexual propagation and vegetative propagation, which has long sexual propagation period, high technical difficulty, and can be eaten by artificial pollination, thus the rhizome is usually adopted, the vegetative propagation coefficient is low, the vegetative propagation coefficient is not easy to depend on the propagation of Konjac, the propagation of Konjac is not easy to be managed by the slow propagation speed, the high propagation coefficient of Konjac is not easy to cause the low, the propagation of Konjac, the Konjac is not easily managed by the propagation of the sweet potato.
At present, when the sweet konjac is planted in the field, the corms which cannot be used as commercial konjac are selected as seeds, and then the seeds are sowed in furrow after the temperature rises in spring, the whole corms are used as seed konjac to breed, one corm can only breed into one seed konjac, and the efficiency is low, so that the research on the breeding method of the sweet konjac seed konjac is necessary to improve the breeding efficiency of the sweet konjac.
Disclosure of Invention
In order to achieve the aim, the invention provides a propagation method of sweet konjac seeds, which solves the problems that the propagation coefficient of sweet konjac is low, the supply is not in demand in the market and the planting technology is not scientific, so that the konjac disease is high in the prior art.
In order to solve the technical problems, the technical scheme adopted by the invention is that the sweet konjac seed propagation method comprises the following specific propagation steps:
step S1: selecting seed balls, namely selecting sweet konjak bulbs without diseases and injuries;
step S2: seed taro is cut into pieces;
step S3: sterilizing the seed taro;
step S4: soil preparation and ridging;
step S5: sowing;
step S6: in the middle management, 15 kg-20 kg of urea is applied to konjak seedlings after emergence, and 50 kg-60 kg of compound fertilizer is applied to konjak seedlings after 1 month; spraying metalaxyl, mancozeb or trichoderma and the like for 1 time every 15 days to prevent diseases; can prevent diseases such as epidemic disease, soft rot and the like;
step S7: harvesting, namely harvesting the konjac in time after the konjac is poured out, selling over 1000g of the konjac as commodity konjac, and storing under 1000g of the konjac as next-year seed konjac.
Further, in the step S1, the size of the seed ball is selected to be 500g to 1000 g.
Further, in step S2, the seed tuber dicing process includes the specific operations of:
step S1, firstly, a kitchen knife is used for cutting off the protruded corms connected to the seed balls, and 15-20 corms of 3-10 g can be obtained;
and step S2, cutting the seed balls into 4 pieces from four sides in the longitudinal direction by a knife around the main buds, cutting each piece into 2 pieces from the middle to obtain 8 pieces of propagation materials, and reserving the remaining main buds as seeds.
Further, in the step S3, the seed taro disinfection is to mix the cut wounds with plant ash, quicklime and bactericide (powder) and then plant the mixture.
Further, the mass ratio of the plant ash, the quicklime and the bactericide is 5-7: 3-4: 1 to 2.
Further, in the step S4, land preparation and ridging are performed, furrowing and ridging are performed according to 1.2m, the height of each ridge is 20 cm-30 cm, and the width of each ridge surface is 80 cm-90 cm.
Further, in the step S5, sowing is carried out in the last ten days of 4 months, ponds are dug on ridges, the distance between each pond is 30cm multiplied by 30cm, 0.5kg to 0.7kg of farmyard manure and 10g to 12g of slow release fertilizer are applied to each pond, then the seed taro is put on the ponds, and 5cm to 10cm of soil is covered on the ponds.
Further, in the step S6, in the middle management, when the weeds grow to a height of 5cm to 10cm, the weeds are manually pulled out or removed by a hoe.
When the seed ball is 500g ~ 1000g in size, the seed ball is large, more bulbs on the corm are obtained, the obtained cut block is large, and the corresponding bred seed ball is also large.
The plant ash, the quicklime and the bactericide (powder) are selected during disinfection, wherein the plant ash is easy to collect and cheap, can absorb moisture of cut wounds and has a certain bactericidal effect; the quicklime has a bactericidal effect, the bactericide is used as powder because the bactericide is easily mixed with the plant ash and the quicklime, and the bactericide is used as little as possible, and many bactericides are antibiotics and are not beneficial to food safety and environmental protection, and finally the quick lime has the following composition ratio of 5-7: 3-4: 1-2, if the component proportion is not in the range, the sterilization effect is poor, and the later-period morbidity of the konjak is high.
The method comprises the steps of applying farmyard manure 0.5kg ~ 0.7kg and slow-release fertilizer 10g ~ 12g at a pond distance of 30cm multiplied by 30cm, applying crop seeds and covering soil 5cm ~ 10cm, wherein the pond distance of 30cm multiplied by 30cm ensures that the planting amount per mu is 4000 strains ~ 5000 and 5000 strains, applying farmyard manure 0.5kg ~ 0.7.7 kg and slow-release fertilizer 10g ~ 12g at each pond is enough to provide nutrition of the konjak, is more wasted and causes fertilizer pollution, covering soil 5cm ~ 10cm and 10cm, can well keep soil moisture in the range, is beneficial to promoting konjak emergence, spraying urea 15kg ~ 20 kg/mu after the konjak seedlings emerge, applying compound fertilizer 50kg ~ 60 kg/mu after 1 month, pulling out or hoeing by hand when the konjak grows to 5cm ~ 10cm, spraying metalaxyl, zinc generation or a seed fertilizer or a fertilizer after 1 month, wherein the urea can provide quick nutrition, the konjak grows up to a high-rate, the konjak, the fertilizer is less in the early stage, the konjak growth of the konjak is too much, the fertilizer for the konjak, the fertilizer is too much, the fertilizer for the konjak, the konjak grows too late stage, the fertilizer is too much, the fertilizer for the konjak, the konjak growth of the konjak grows too much, the konjak, the fertilizer is too much, the fertilizer is.
The invention has the beneficial effects that:
1. the propagation coefficient is high, the propagation speed is high, and 20 ~ 30 seed taro can be propagated by 1 seed ball after propagation for 1 year.
2. The economic benefit is good, 5000 yuan is invested in each mu, 1000 kg ~ 1200 kg of seed taro can be produced, the income per mu is 15000 yuan ~ 18000 yuan and the income per mu is 10000 ~ 13000 yuan on average according to 15 yuan per kg.
3. The ridge-dividing cultivation is favorable for drainage, ventilation and air permeability, the konjak grows robustly, the later-stage intertillage management is more favorable, the artificial damage to the konjak is reduced, and the morbidity of the konjak is reduced.
