Sweet potato planting technology and management, sweet potato planting technology and management are

1. Apply plantar fertilizer and prepare the land reasonably.

1. Fertilization: Since sweet potatoes are generally planted on sandy and thin land, it is necessary to apply foot fertilizer to improve soil fertility in order to obtain high yield. Generally, about 5 square meters of soil and miscellaneous manure per mu, 25 kg of diammonium phosphate and 25 kg of potassium sulfate are appropriate.

2. Land preparation: sweet potato is a root crop, which is suitable for growing in an environment with deep soil, loose soil and good aeration. Deep tillage can thicken the soil layer, improve soil aeration, and is conducive to the expansion of potato pieces.

The depth of deep ploughing is generally 30 cm. It is better to use ridge cultivation for plots with good soil fertility, but sandy land with thin soil fertility and large sand content should be cultivated with flat or low ridges.

Second, select excellent seeds, timely early planting, reasonable dense planting.

1. Seed selection: select high-quality and high-yield varieties. For example, detoxified Beijing 553, detoxified Xushu 18, Xinnong 1, Xinong 431, Yanshu 27, Sushu 8, Yushu 7 and other short-vine high-yielding varieties.

3. Density: long vine varieties and fertile plots should be sparsely planted, and short vine varieties and thin land should be densely planted. 3000-3500 plants per mu of fertile land and long vine varieties, 4000 plants per mu of thin land and short vine varieties, with row spacing of 60-70 cm and plant spacing of 30 cm.

3. Field management.

1. Seedling planting: select strong seedlings to be planted in a horizontal shallow planting method, and plant the seedlings to the southeast and downwind to prevent the wind from scratching the seedlings. It is advisable to bury the soil inch deep and expose 3-4 leaves on the ground. When planting seedlings, water them sufficiently, and replenish them in time to ensure that the seedlings are complete.

2. Early cultivation, frequent weeding and early management. Cultivating loosens the soil, increases soil aeration, raises ground temperature, and eliminates weeds. Sweet potatoes are drought-tolerant crops, and they should generally not be watered more in the early stage, but when the soil is too dry, they can be watered with a small amount of water.

The long-vine varieties are topped when the stems and vines grow to about 1 foot, which promotes the stubby and short stems and branches, which has a certain effect on increasing yield.

3. Medium-term vine control: July to August is the season of high temperature and rain, the stems and leaves grow fast, and the potato pieces expand slowly, so the main control should be taken to prevent the stems and leaves from growing. Long vine varieties can be sprayed with paclobutrazol 2-3 times per mu, and short vine varieties such as stem vines can also be sprayed appropriately.

The farmers who cultivate sweet potatoes in our land have the habit of turning the vine after the rain, but turning the vine hurts the stems and leaves, reduces photosynthesis, can not increase the yield, but reduces the yield, and should be changed to the vine lifting. After lifting the vine in time, the stem and vine are still put back in place, so as not to damage and flip the stem and leaves, prevent the growth of adventitious roots in the stem nodes, and control the growth of the stems and leaves, so as to achieve the purpose of increasing yield.

Sweet potatoes need to be planted with rich organic matter content and good drainage sandy loam soil, healthy sweet potato seeds need to be planted in the soil when planting, and water water to the soil, wait for the seeds to grow seedlings, and then cut off the shoots on the top of the seedlings for cuttings planting, which can provide inorganic fertilizer for the plants after planting. How to plant and manage sweet potatoes 1. Choose the soil To plant sweet potatoes, you need to choose the right soil. Sweet potatoes are suitable for growing in soil with rich organic matter content and loose soil, so you can use sandy loam or humus soil with rich trace element content and good drainage when planting, and you need to renovate the soil before planting to improve the air permeability of the soil.

Seedling treatment: Seedling treatment is also required when planting sweet potatoes. First, you need to select healthy sweet potato seeds with young shoots, then plant them in fertile and loose soil, and water the soil with unpolluted river water, soak all the soil, and if the ambient temperature is low, you can also cover the planting area with plastic wrap to keep warm. 3. After planting and waiting for the sweet potato seeds to grow smoothly, you can cut off the young branches at the top of the long vine, and then insert them into the soil prepared in advance, and pour mineral-rich pure water or natural water into the soil to keep the soil in a moist state, so that the seedlings can adapt to the planting environment as soon as possible and resume growth.

4. Later maintenance in the later maintenance of sweet potatoes, can provide all-day sunshine for the plants, so that the plants can carry out photosynthesis normally, can also provide sweet potatoes rich in nitrogen, phosphorus and potassium mixed fertilizer, improve the growth rate of plants, in the fertilization of the best fertilizer can be diluted to provide to the plant, so as to avoid fertilizer damage to sweet potatoes.

Sweet potatoes are warm-loving crops, native to the tropics, sensitive to low temperatures, and not frost tolerant. The temperature in the peak period should not be lower than 21 degrees Celsius, the optimal growth temperature is about 25 degrees Celsius, the growth will slow down when it exceeds 35 degrees Celsius, the growth will be stagnant below 15 degrees Celsius, and the plants below 10 degrees Celsius will die due to low temperature and cold damage.

After the young shoots are unearthed, the temperature is about 25-30 degrees Celsius, too low is the growth is slow, too high the tissue is tender, the seedlings are slender, and the seedling quality is poor. When transplanting the field, it is better to ensure that the soil temperature of 5 cm is stable above 16 degrees Celsius, and the temperature is 18-20 degrees Celsius. The optimal soil temperature at the root expansion stage is 22-23 degrees Celsius.

Sweet potato is a light-loving short-day crop, which can improve the intensity of photosynthesis, increase the accumulation of dry matter, and facilitate the formation and expansion of root blocks when the light is sufficient. When the light is insufficient and the intensity is not enough, the photosynthesis of sweet potato seedlings is weakened and the accumulation of organic matter is reduced.

The yield of sweet potato per mu is 4000 kg, and the planting management in this way can slow down the seedlings and grow well and the yield is high.

The cultivation of sweet potato is relatively simple, it is a root plant, like potatoes, like potassium fertilizer, followed by phosphorus fertilizer, of course, nitrogen fertilizer is also indispensable. Ridge forming is one of the key construction: the width of the ridge can be about 40 cm, the ridge is deep into a fertilizer ditch, organic fertilizer, inorganic fertilizer into it, the soil on both sides of the ridge is turned together.

Then it is the seedling cutting, the plant spacing can be as needed, the maximum can not be greater than 20 cm, the nest is watered, the nest is applied seedling fertilizer (not too much), and the nest is completed.

1. Germination: When planting sweet potatoes, you need to place the potato pieces in an environment with a temperature of 28 degrees for germination. 2. Soil:

Choose a loose, breathable soil with sufficient base fertilizer for planting. 3. Top dressing: After the sweet potato emerges, it is necessary to apply a thin human and animal manure for it.

4. Pruning: Cut off the lush branches and leaves of sweet potatoes to promote their growth tubers.

1. Germination method

When planting sweet potatoes, you need to germinate them first, you can choose strong and disease-free tubers as seeds, and then soak them in warm water at 45 degrees for 12 hours to make the tubers absorb enough water, and then place the sweet potatoes in an environment with a temperature of about 28 degrees to promote their rapid germination.

2. Soil conditions

Sweet potatoes are suitable for growing in fertile and loose and airy soil, when planting sweet potatoes, you need to plough 30-40 cm of soil, remove stones and clods in the soil, call the mountain to make it softer, and apply nitrogen, phosphorus and potassium compound fertilizer and rotten organic fertilizer to the soil to promote the vigorous growth of sweet potatoes.

3. Planting method

When planting sweet potatoes, you need to bury the potato pieces into the soil, water them again, and cover them with a layer of plastic film to maintain the normal growth of sweet potatoes, wait for the sweet potatoes to emerge, you need to apply a thin fertilizer for them, and during the expansion period of sweet potato tubers, you need to spray potassium dihydrogen phosphate on the cavity of its leaves.

4. Pruning treatment

When cultivating sweet potatoes, it is necessary to cut off the branches and leaves that grow too densely in the plant, so as not to lose excess nutrients, so that the nutrients are concentrated in the tuber, and when the sweet potato branches grow to 40-60 cm, the leaves at the top of the branches need to be cut off to eliminate the top advantage of the plant and increase the yield of sweet potatoes.

Sweet potato planting techniques and management are:

1. Soil preparation and fertilization.

It is very important to choose a fertile and loose plot for planting sweet potatoes, when planting, it is necessary to turn the plot deeply, and then apply enough organic fertilizer, wrap the fertilizer in the ridge and then use a hoe to open a row on the back of the ridge to keep the fertilizer of the plot uniform.

2. Seedling planting.

Lay the potato seedlings flat along the furrow, bury them in the soil, and water them to promote their growth. When the stool barred sweet potato seedlings grow to a certain length, it is necessary to do a good job of transplanting and planting, in order to promote the rapid growth of the root system, it is necessary to water the roots.

3. Scientific fertilization.

After planting 15 days, it is necessary to supplement the farmhouse fertilizer in time for the jujube hole, supplemented by chemical fertilizer, the plot with better fertility needs to be applied to 25-30 kg of urea, 30-50 kg of phosphorus, 30-40 kg of potassium sulfate, sweet potato growth process, if the leaves are yellow, timely application of long vine fertilizer, mainly phosphorus and potassium fertilizer, in the potato swelling period, it is necessary to strengthen water management, reasonably control the reasonable growth of tubers and stems and leaves, and strengthen pest control.

4. Foliar spraying.

Sweet potatoes in the tuber growth period, the use of potassium dihydrogen phosphate foliar spraying, can help sweet potatoes sweeten, improve the quality of sweet potatoes, stop watering 15 days before harvest, such sweet potatoes taste better, shelf-stable.

5. Disease prevention and control.

Sweet potatoes are prone to ant weevils, black spot and other pests and diseases, in the process of sweet potato growth, we should pay attention to cultivation management, once the ant weevils appear, it is necessary to use 40% dimethoate EC with water spray, black spot can use 50% carbendazim 300-500 times liquid for soaking seedlings, can play a good control effect.

Sweet potato planting techniques and management include: soil selection, fertilizer application, planting methods, irrigation management, pest control and harvest management.

1. Soil selection: sweet potatoes like warm, moist and well-drained soil, and it is advisable to choose fertile, loose and well-permeable soil.

2. Fertilizer application: sweet potatoes have high requirements for fertilizer, and sufficient fertilization should be carried out before planting. Generally speaking, 3000-4000 kg of organic fertilizer and 200-300 kg of compound fertilizer are used per mu.

3. Planting method: sweet potato planting is suitable for strip sowing, hole sowing or film mulching and sowing. Before planting, the seed Nay's lead potato should be treated, such as soaking, fumigation, etc.

4. Irrigation management: Sweet potatoes need sufficient water for growth, and reasonable irrigation should be carried out according to the degree of soil dryness and wetness and climatic conditions. Generally speaking, the water consumption per mu during the growth period of sweet potatoes is about 1500-2000 cubic meters.

5. Pest control: Sweet potatoes are susceptible to pests and diseases, and measures should be taken to prevent and control them in time.

6. Good harvest management: the growth period of sweet potatoes is 3-4 months, and when the leaves begin to wither, they can be harvested. This ensures that the harvested sweet potatoes are the freshest.

Choose soil: Choose a deep sandy soil to grow sweet potatoes. Sowing seedlings:

Choose tubers with bud spots and are free of pests to sow seeds, and cut off and insert them into the soil after the seedlings grow. Scientific top dressing: about 15 days after the seedling planting, apply human and animal fertilizer once.

Field management: Sweet potato seedlings grow to about 50 cm and remove the tender tips.

1. Select the soil

Sweet potato does not have high requirements for soil, strong adaptability, choose deep soil layer, loose and breathable sandy soil planting, before sowing the soil to break the soil, fine, deep ploughing about 30 cm, apply farmhouse fertilizer as base fertilizer, and level the ground after mixing evenly with the soil.

2. Sow seeds and raise seedlings

When sowing sweet potatoes, it is necessary to choose potato pieces with sprout points and no pests and diseases, sow seeds in strip sowing, water enough water after sowing, cover the ground with transparent film, and suppress it with soil at intervals of about 1 meter on the surface of the mulch, wait for the seedlings to grow, cut off the seedlings and insert them directly into the ground to keep the soil moist, and the growth will resume after slowing down the seedlings.

3. Scientific top dressing

About 15 days after the planting of sweet potato seedlings, it is necessary to apply a seedling fertilizer to supplement nutrition, which helps the growth of seedlings, generally use diluted human and animal fertilizer is the best, wait for 30 days and need to apply potato fertilizer, mainly use nitrogen fertilizer, sweet potato rhizome swelling, when cracks appear in the ground, it is necessary to apply diluted urea to irrigate the ground, and timely supplement nutrients, which is conducive to improving yield.

4. Field management

Sweet potato seedlings grow to about 50 cm, need to be pruned and topped in time, to remove the tender tips, with sterilized scissors to grow vigorously and more branches of the branches, cut 2-3 branches, so that nutrients flow back to the main stem to get more nutrients, reduce nutrient consumption.
