Description

Technical Field

[0001] The invention relates to the technical field of konjac planting, and in particular to a method for cultivating konjac. Background Art

[0002] Konjac is a plant of the Araceae family and the genus Amorphophallus. Its tuber is oblate, 7.5 to 25 cm in diameter, with a dark reddish-brown, slightly concave center. The petiole is 45 to 150 cm long, 3 to 5 cm thick at the base. The inflorescence stalk is 50 to 70 cm long, 1.5 to 2 cm thick, and the same color as the petiole. The berries are spherical or oblate, yellow-green when ripe. Flowering occurs from April to June, and the fruit ripens from August to September. Konjac is primarily distributed from the eastern Himalayas to Thailand, Vietnam, the Philippines, Japan, and China. In China, it is found in Shaanxi, Gansu, Ningxia, and the Jiangnan provinces. Konjac is a semi-shade plant that prefers warmth and avoids high temperatures. It thrives in well-watered, organic-rich sandy loam and thrives in moist environments such as stream valleys, ravines, under forests, or at the edges of forests. It can also be cultivated in front of or behind houses or in the corners of fields.

[0003] Konjac propagation methods include seed propagation, tuber propagation, rhizome propagation, and cutting propagation. When using the seed propagation method, the first step is to select disease-free, well-formed konjac seed tubers. After sterilization and disinfection, they are sown in early spring at a controlled planting density. After planting, the cultivation process involves mulching and shading, fertilization and water management, intertillage and weeding, and pest and disease control. Seed propagation maximizes the preservation of the parent plant's favorable traits, ensuring that the offspring konjac shares the same growth habits, yield, and quality as the parent, thereby stabilizing the variety's advantages.

[0004] However, since seed taro reproduction is asexual, long-term asexual reproduction will lead to the degeneration of konjac seed taro, resulting in low germination rate during cultivation, decreased konjac yield, and a significant decrease in the nutrient content of the offspring konjac. Summary of the Invention

[0005] The invention provides a konjac cultivation and planting method, which effectively solves the technical problem that long-term asexual reproduction causes the seed taro variety to degenerate, thereby resulting in a decrease in the germination rate and yield of the offspring konjac and a corresponding decrease in the nutrient content of the offspring konjac.

[0023] The konjac cultivation and planting method provided by the invention is simple to operate, and various raw materials are easily available, and the problems of low emergence rate and low yield of konjac seed taro and low nutrient content of offspring konjac are effectively solved, thereby realizing efficient breeding of konjac seed taro. DETAILED DESCRIPTION

[0024] To enable those skilled in the art to better understand and implement the technical solutions of the present invention, the present invention is further described below with reference to specific examples, but the examples are not intended to limit the present invention. The following experimental and detection methods are conventional methods unless otherwise specified; the reagents and raw materials are commercially available unless otherwise specified.

[0025] The present invention aims to solve the technical problems mentioned in the background technology in that: since seed taro reproduction belongs to asexual reproduction, long-term asexual reproduction can cause the variety of konjac seed taro to degenerate, thereby causing a low emergence rate, a decrease in konjac yield, and a greatly reduced nutrient content in offspring konjac during cultivation. Based on the technical problems in the above-mentioned konjac cultivation and planting, the present invention provides a konjac cultivation and planting method.

[0026] The technical solution of the present invention is analyzed and explained in detail below.

[0027] The present invention provides a method for cultivating and planting konjac, comprising the following steps:

[0028] Pretreatment: taking 80g-120g of konjac seed taro, drying them at 20-26°C, and using 70%-80% by volume alcohol to disinfect the konjac seed taro for 10 minutes to obtain pretreated konjac seed taro.

[0029] Activation treatment: adopt 300 times to 400 times of Taifujing liquid to soak the described pre-treated konjac seed taro for 2h to 3h to obtain the konjac seed taro after sterilization, in a mixed atmosphere of nitrogen and ozone, feed 22 ℃ to 28 ℃ of steam and carry out heat activation treatment to obtain heat-shocked seed taro, the above-mentioned heat shock treatment process strengthens the growth potential of the konjac seed taro, and fully activates the catalase in the seed taro, thereby gradually reduces the accumulation of the harmful substance hydrogen peroxide, for promoting the germination of the subsequent seed taro, creating an excellent intracellular environment; the described heat-shocked seed taro is immersed in an activation solution mixed with brassinolide, calcium sulfate, ethiocarb and sodium nitrophenolate, and oven dry to obtain the activated seed taro, the above-mentioned activation solution enters the seed taro cell and activates the intracellular cytokinin oxidase, thereby effectively regulated the content of cytokinin, accelerated the seed taro cell division and differentiation process, and then regulated the seed taro germination speed and germination quality, effectively solving the problems of low emergence rate and yield decline of the progeny konjac.

[0030] Cultivation and planting: sowing the activated seed taro in a seedling pot filled with nutrient soil with a humidity of 60% to 70% at 10° C. to 16° C., and harvesting the konjac through planting management.

[0031] Described Nutrition Soil is by peat soil, leaf mold, organic fertilizer, nitrogen, phosphorus and potassium compound fertilizer, sulphur, and pomace mixes, and watering fermentation is decomposed and obtains.The Nutrition Soil of above-mentioned fermentation is decomposed and can provide the required nutrient component of plant taro growth, because activation treatment process strengthens the growth potential of konjaku plant taro, improves the growth characteristics of konjaku plant taro itself, therefore plant taro for the absorption utilization rate of the nutrient component in Nutrition Soil higher, thereby effectively improves the content of the nutrient substance gathering in konjaku.

[0032] In the above technical scheme, the germination rate and germination quality of konjac seed taro are improved through activation treatment and nutrient soil cultivation, the nutrient content of offspring konjac is improved, and the technical problem that the emergence rate and yield of offspring konjac decrease and the nutrient content of offspring konjac also decreases is effectively solved.

[0033] In order to break the dormancy of konjac seed taro, improve cell division and differentiation process, thereby improve the budding speed and budding rate of konjac seed taro, in the described activation solution, the mass concentration of brassinolide is 0.012%~0.036%, the concentration of calcium sulfate is 1.0mg / L~4.0mg / L, the concentration of ethionine is 0.6mg / L~4.8mg / L, and the concentration of sodium nitrophenolate is 0.05mg / ~1.5mg / L. It should be emphasized that in the above-mentioned activation solution, the consumption of ethionine and calcium sulfate has a greater impact on the budding situation of konjac seed taro. If the concentration of ethionine is lower than 0.6mg / L, the cell division speed is slow and budding is slightly later; if the concentration of ethionine is greater than 4.8mg / L, although the seed taro sprouts early, the seed taro growth rate after sprouting is uneven and the stability is poor. As for calcium sulfate in the activation solution, its content has a greater impact on the germination rate of the seed taro. When it is lower than 1.0 mg / L or higher than 4.0 mg / L, the germination rate of the seed taro is not greatly affected, but the germination rate is not good.

[0034] In order to further improve the sprouting quality and the sprouting rate of konjak seed taro, the quality of each described konjak seed taro is 80g~120g, and 1 described heat shock seed taro adopts the activation solution of 400mL~500mL to carry out immersion treatment.When the amount ratio of heat shock seed taro and activation solution is not used in the above-mentioned limited scope, as when adopting 600mL activation solution immersion treatment, its sprouting effect is substantially equal to the sprouting effect of konjak seed taro in above-mentioned consumption range, but the consumption of activation solution is more, and cost increases; And when adopting 300mL activation solution immersion treatment equal weight heat shock seed taro, because the consumption of activation solution is relatively less, so the sprouting effect of konjak seed taro is unsatisfactory, and sprouting speed is slow, and sprouting rate is also lower.

[0035] In order to provide a suitable soil growth environment for taro, the pH value of the nutrient soil is controlled to be 6.0-7.5.

[0036] In order to further improve the absorption and utilization rate of various components in the nutrient soil by the taro seeds, the preparation method of the nutrient soil comprises the following steps:

[0037] The raw materials are weighed according to the following weight parts: 50-100 parts of peat soil, 50-100 parts of leaf mold, 6-12 parts of organic fertilizer, 2-8 parts of nitrogen, phosphorus and potassium compound fertilizer, 16-30 parts of fruit residue and 0.5-6.8 parts of sulfur.

[0038] The above raw materials are mixed to obtain a mixture, which is piled up and fermented and decomposed at 25°C to 40°C and 60% to 70% humidity for 15 to 30 days. After fermentation and decomposition, the components in the nutrient soil are activated and are more easily absorbed and utilized by the seed taro after sowing.

[0039] In order to further promote the healthy growth of the seed taro, EM bacterial agent is added to the mixture at a mass ratio of 1:0.02-0.04, and the mixture is piled after mixing.

[0040] In order to improve the absorption and utilization of subsequent activation solution by pre-treated konjac seed taro, the pre-treated konjac seed taro after sterilization is placed in a mixed atmosphere of nitrogen and ozone, the volume ratio of nitrogen to ozone is 1:0.05~0.4; The flow rate of described steam is 50mL / min~80mL / min. In the above-mentioned processing mode, if ozone content is higher, the growth activity enzyme in the seed taro, such as protein enzyme, lipase can be over-oxidized, thus being unfavorable for the germination of the seed taro, even if the activation solution can be absorbed, the component in the activation solution cannot play a positive promoting role to the germination of the seed taro, so it affects the germination rate and the germination quality of the seed taro.

[0041] To further improve the growth characteristics of the seed taro, the heat activation treatment time is controlled to 0.5h to 1.5h. If the heat activation treatment is too low, the germination rate of the seed taro is low, and the seed taro cells cannot fully absorb and utilize the activation liquid, so the germination effect is poor. If the heat activation treatment time exceeds 1.5h, it is excessive heat activation treatment, and the growth enzymes of the seed taro cells are destroyed, so the germination effect will inevitably be affected.

[0042] It should be emphasized that, similar to the heat activation treatment, the heat-shocked taro seeds are immersed in the activation solution. Even if the activation solution has a positive promoting effect on the growth and germination of the taro seeds, the soaking time must be controlled within 2h to 4h. Similarly, if the soaking time is less than 2h, the activation solution is not fully utilized and the germination effect is affected; but if the soaking time exceeds 4h, although the taro seed cells absorb a sufficient amount of activation solution, the moisture content of the taro seed is also high. Excessive moisture content is not conducive to the germination of the taro seed.

[0043] In order to ensure uniform stability of germination, the diameter of the seedling pot is 30cm~50cm, the height of the pot is 30cm~60cm, the sowing depth is 10cm~15cm, and the activated seed taro is sown at an angle of 45°. In order to carry out unified planting management, the diameter of the seedling pot used in the following embodiments of the present invention is 40cm and the height of the pot is 50cm.

[0142] The technical effects of the konjac cultivation methods provided in Examples 1 to 8 and Comparative Examples 1 to 4 were tested, and the results are shown in Tables 1 and 2.

[0146] 2. Effects of different treatments during sowing and propagation on konjac yield and nutritional content

[0147] Table 2 Effects of different treatments on konjac yield and nutritional components

[0148]

[0149]

[0150] As shown in Table 1 and Table 2, the konjak planting method provided by the present invention has effectively improved the budding effect, output and the nutritional component content of konjak of konjak seed taro, cultivated by adopting konjak cultivation planting mode of the present invention, the budding time of konjak is in advance, can sprout on the 8th day after planting, and germination rate is up to 97%, and per mu yield can reach 2604kg / mu, and in every 100g konjak, dietary fiber is up to 6.0g, and the content of vitamin A is 20 μ g. However, after adopting the implantation method of comparative example 1~comparative example 5 after embodiment 1 adjustment to cultivate, budding rate, output and the nutritional component of konjak have produced different impacts. The reason analysis is as follows:

[0151] In Comparative Example 1 and Comparative Example 2, the consumption of ethyl garlici in the activation solution is adjusted respectively, ethyl garlici is outstanding for the cytokinin oxidase effect in the activating cell, reducing the ethyl garlici consumption causes the cytokinin content to reduce, so slowed down cell division and the differentiation speed of planting taro, so show as the phenomenon that sprouts slightly later (Comparative Example 1 shows as sprouting the 11th day after sowing, and Comparative Example 2 then shows as sprouting the 16th day), germination rate in the later stage and konjac yield have also been impacted, the konjac per mu yield that Comparative Example 2 does not add ethyl garlici is only 1986kg / mu, and in every hectogram konjac, the content of dietary fiber is 4.8g, and the content of vitamin A is 16 μ g.

[0152] Comparative Example 3 is to reduce the concentration of calcium sulfate in the activation solution in Example 1. The reduction of the calcium sulfate dosage has an impact on the activation effect of the activation solution on the taro, affects the absorption of brassinolide in the activation solution by the taro, thereby affects the activity of protease in the taro, although sprouting is not significantly affected, the germination rate is greatly affected, sprouts on the 9th day after sowing in Comparative Example 3, but the germination rate is only 80%, thereby causing the per mu yield of planting konjac and the nutritional ingredients contained in the konjac to all reduce.

[0153] Comparative example 4 and Comparative example 5 are respectively that the ozone in embodiment 1 is replaced by oxygen and remove ozone atmosphere, because under ozone atmosphere, the catalase in the konjaku kind taro is fully activated, effectively reduce the accumulation of objectionable substance hydrogen peroxide, comparative example 4 is adjusted to oxygen by ozone, the activating effect of catalase in the kind taro is greatly weakened, therefore the hydrogen peroxide content accumulated in the plant taro increases, thereby has affected the germination effect of the konjaku kind taro to a certain extent, germination rate is 91%, with the comparison of comparative example 4, comparative example 5 directly removes ozone atmosphere, in like manner the activity of catalase is not fully activated, plant the taro intracellular hydrogen peroxide content more than comparative example 4, therefore show as germination rate and only be 85%, per mu yield only is 1950kg / mu, and the content of dietary fiber is as low as 3.6g / 100g.

[0154] In summary, the konjac cultivation and planting method provided by the present invention effectively improves the germination rate, per mu yield and nutritional components of konjac, is simple to operate during cultivation and planting, and various raw materials are easily available. The problems of low germination rate and low yield of konjac seed taro and low nutritional component content of progeny konjac are effectively solved, thereby achieving efficient breeding of konjac seed taro.

[0155] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
