How to plant milled taro and how to plant milled taro to have a high survival rate?

Introduction: The traditional artificial planting and harvesting mode has inhibited the development of konjac industrialization. In order to speed up the development speed and process of this industry, promote the construction of new countryside and economic development, the promotion of konjac mechanized planting and harvesting technology has become a top priority.

This paper briefly describes the key points of konjac mechanized planting and harvesting technology, in order to promote the development of konjac mechanization industry.

Since the 80s of the 20th century, China's konjac has started the development of industrialization, and in recent years, under the dual promotion of strong policy support and market demand, many growers have begun to expand the scale of planting, but so far, konjac is generally planted artificially. With the development of China's market economy, a large number of rural labor force has been transferred to the city, resulting in an increasing proportion of labor costs in vegetable production costs, and it is difficult for farmers to continue to do intensive farming, and the level and efficiency of vegetable output have declined. According to the survey, the number of labor force engaged in agricultural production in China has dropped from 70% in 1978 to about 35% at present[1].

According to the survey in recent years, 40 pieces of labor are required to produce 667 m2 of konjac, about 3 200 yuan. Therefore, it is of great significance to improve the cultivation methods and optimize the management measures, adopt the mechanized planting mode, and establish supporting technical regulations, which are conducive to reducing labor intensity and production costs, and are of great significance to promote the reasonable transfer of labor, stabilize the planting area of konjac, and improve the yield and quality of konjac.

1. Land selection and land preparation.

Water and dry river land, terraced land, and hilly land with a slope of less than 8° should be selected to be planted on relatively flat terrain and with a certain scale, which is conducive to mechanized operation [2]. With loose soil, fertile soil (containing organic matter), alkaline hydrolyzable nitrogen 200 300 mg K

1.Soil selection and land preparation.

Konjac likes a warm, moist, semi-shaded growing environment, and has very strict requirements for soil, so it should be planted in slightly acidic or neutral humus soil with fertile soil and good drainage conditions, and the pH value of the planting soil is better maintained between 6-7. The planting site should be in a cool and ventilated place, preferably with shade, or with shelter to block the sun. After choosing the planting land, the land should be deeply turned to a depth of about 40 cm.

2.Sowing and propagating.

Konjac is generally propagated by sowing taro, and the taro should be treated before sowing to prevent the invasion of pathogens and improve the survival rate. September is a good time for sowing, generally using the method of strip sowing, with a depth of about 5 cm. Be careful not to let the taro come into contact with the fertilizer when sowing.

3.Field management.

Konjac likes fertilizer, and the fertilization is mainly fermented farmhouse fertilizer, supplemented by chemical fertilizer. In addition, it is necessary to pay attention to timely topdressing, as the lack of fertilizer during the konjac growth period will lead to an increase in the probability of disease and a decrease in yield. Konjac is drought tolerant, as long as it is watered several times in the seedling stage, there is basically no need to water in the rest of the period, and it should be noted that the drainage measures in the rainy season should be done well to avoid tuber rot.

Precautions for konjac planting.

1.Soil conditions.

Konjac is not suitable for planting in plots with clay soil, so you must pay attention to choosing yellow or purple soil and sandy soil and sandy soil, otherwise the survival rate of konjac will be very low. In addition, it should be noted that continuous cropping is not allowed, nor can it be planted on land where the previous crops were continuous crops, even if the previous crops were peppers and tobacco.

2.Planting temperature.

The konjac grows at a temperature of about 15 degrees Celsius, and the sowing time is in April every year, usually about 25 days for budding, and transplanting is completed in mid-May. During the planting process, it is better to keep the temperature in the field between 13-18 degrees.

3.Planting density.

The planting density will also affect the growth of konjac, an average of about 3,000 konjac plants can be planted per mu, and each mu can not exceed 4,000 plants.

4.Fertilizer and water management.

When planting konjac, apply sufficient base fertilizer as much as possible, and do not carry out top dressing. Watering is also different from other crops, just water enough water at the seedling stage, and then reduce the number of watering as much as possible, which is more conducive to its growth. In addition, konjac is a coarse crop and does not require much field management.

1) Choose konjac seeds that are resistant to low temperature chilling injury;

2) will 7;

The low-temperature cold-damage resistant konjac seeds harvested in August are graded according to the weight of 100 seeds, and then dried and stored in storage, and stored in constant temperature cold storage or sand;

3) in the coming year 2;

In April, concentrated germination was carried out in the light incubator or germination room;

Concentrated germination 23;

After 40 days, pick the buds to grow;

2cm of squire seeds;

4) Coating of solid seeds after concentrated germination or mulching and shading treatment after direct sowing, such as opening;

5) After mulching treatment, spray leaf old oak flour fertilizer from the konjac head changing stage to the konjac bulb expansion stage.

The present invention has the advantages of improving the emergence rate, reducing the incidence of disease in the field, enhancing the resistance and improving the yield of seed cultivation.

When planting konjac, the land requirements are deep, loose and fertile type, the planting environment is best in a half-shaded and half-sunny place, in the spring of 3-4 months, the first land is fertilized, and then the konjac bulb is planted into the soil, and then covered with a layer of 3-5 cm of pine hair or straw, it should be paid attention to apply thin fertilizer frequently during the growth period.

1. Soil requirements

Konjac has certain requirements for soil, it is best to choose a deep, loose and breathable and fertile sandy loam soil block to plant, it is not suitable to plant it in the clay soil, otherwise konjac will grow poorly, and the soil needs to be disinfected and insecticidal before planting.

2. Suitable environment

Konjac also has certain requirements for the environment, it likes to grow in a warm and humid environment, so it is suitable to plant it in a place that is half shade and half yang, and it is generally best planted on the north slope, and it must not be planted in an environment with too much light, otherwise konjac is prone to dryness.

3. Planting method

The most suitable time to plant konjac is in spring in March and April, first prepare the land and fertilize, and then plant the konjac bulb into the soil, cover it with a thin layer of soil, and then cover it with a layer of 3-5 cm of pine hair or straw, which can play a role in moisturizing and keep the soil loose and breathable.

4. Maintenance management

Konjac needs to be watered once after planting, it likes moisture and is afraid of waterlogging, it is most suitable to keep the soil slightly moist daily, after the konjac seedlings and leaves, it can be applied a compound fertilizer to promote its vigorous growth, and we should pay attention to weeding during breeding, and we also need to control pests and diseases.

Wet places should be watery but not flooded.
