In recent years, the prospects for the cultivation of konjac have become better and better. More and more farmers have begun to choose to plant konjac, and there are many ways to plant konjac. Today, Xiaobian will talk to you about the advantages and cultivation of planting konjac under the forest. method.
1 The concept of planting under the forest and its advantages
1.1 The concept of planting under the forest
Planting konjac under the forest is to plant the burdock roots, small bulbs and konjac species of the konjac under the woods, without applying chemical fertilizers or pesticides, allowing them to grow naturally;
Every year, before the emergence of konjac, artificial methods are used to remove weeds (we also use artificial removal of weeds during the growth process). In the harvest season, the konjac that can be used as commodities will be collected and sold according to the growth situation; Left the small konjac species and the burdock roots continue to grow under the forest, and more than 200g of konjac is used for commodities. The breeding technique of konjac planting is planting under the forest (the plot is most suitable under the eucalyptus forest). It is suitable for promotion in areas where the frozen soil layer does not exceed 5 cm in winter.
1.2 Advantages of planting under the forest
1.2.1 Restoring the species of konjac seeds
Konjac originated from tropical forests, and it has a unique living habit of cultivating konjac in humid, warm, low-light and organically rich environments. With the continuous development of the konjac industry, the growth environment of konjac has changed, such as contiguous planting, large-scale production, large-scale mixed planting, seedless quotation, continuous or intermittent disease, resulting in the degradation of konjac species and frequent diseases. The output is not high and the efficiency is low. Planting the roots of the konjac burdock, the small bulbs and certain konjac species under the forest, and returning it to the original living environment, can restore the original traits of the konjac.
1.2.2 Reduce konjac disease
Planting konjac under the forest, man-made damage is reduced, harvest time can be digging large and small, single plant collecting and digging, choose strong and weak. The harvested konjac species has a smooth surface, a shallow bud eye, a strong growth potential, and a high expansion coefficient of the bulb; few diseases occur during the planting process, and reducing the occurrence of the disease reduces the risk of konjac production.
1.2.3 Saving production costs
The cost of planting under the forest is low and the risk is small. The planting can be multi-year income. When the market price is high, you can dig large and small conversion plants to develop commodity konjac; when the price is low, let it grow under the forest, it will not affect the development; Money to buy a variety of konjac, save money. Under the forest, winter can be wintered on the spot. Before and after the frost, the holes left by the petioles will be covered with soil, and the leaves and weeds will cover the winter. Reduces the handling and storage processes, saves labor, reduces man-made damage to the konjac, and reduces costs.
1.2.4 Achieving a benign environment that increases income
Planting konjac under the forest is not only low cost, but also conducive to the development of konjac in the field, and improves the land utilization rate. Planting konjac under the forest also inhibits the growth of weeds and solves the problem of management and management of returning farmland to forests, which can improve the survival rate of seedlings and Provide a good shade environment and fertility conditions for the growth of konjac; form a virtuous cycle.
2 Basic methods of planting konjac under the forest
2.1 Selection of woodland
The leguminous tree species are selected to be the best in the eucalyptus tree. The locust is a pinnately compound leaf, the leaves are hypertrophy, and the rot is rich in multivitamins. The roots are strong and germinated. They are superficial roots, the roots are very developed, and the roots are parasitic. There are a large number of rhizobium bacteria, which can improve the soil and increase the soil organic matter; make the plot resistant to drought, high temperature and regulate the pH of the soil. The improvement of these traits is conducive to the growth of konjac to reduce the occurrence of diseases.
2.2 Woodland density and leaf shading
The row spacing of forest trees should not be less than 2m, and the concealment degree of forest land is about 50%. If the forest is too tall to remove some of its branches, the forest konjac can accept the sun.
3 timely seeding and other requirements
The key to planting konjac under the forest is the first planting. Spring is the most suitable period in April. Before planting, the forest land will be thoroughly deeped once, the debris will be removed, and then the seeds will be selected. The konjac seeds that are susceptible, rotted, aged and mutated cannot be planted in the forest area, and can be planted separately after planting; The density of 4,000 plants is planted. Other planting management techniques are the same as those of field cultivation techniques.
