When is the best time to grow sweet potato seedlings?

Because the amount of planting is relatively large, so most of them are home-raised, few people buy sweet potato seedlings, every year after the beginning of spring, that is, at the end of February to early March, they will pick out the sweet potato seeds that have been carefully selected from the cellar and start to raise seedlings. The so-called sweet potato seedling is actually to cultivate sweet potato vines with the stems of sweet potatoes, and then cut off the vines for cuttings after the vines grow. Therefore, sweet potato seedlings must be completed before sweet potato seedling cuttings.

How far in advance does this time need to be? To put it simply, it usually takes one and a half to two months.

In terms of yield and variety, the performance is quite good, short vines do not need to turn over the vine, drought resistance, strong stress resistance, suitable for cultivation in a variety of soils, simple management, high yield, the most engaged mu yield can reach 7000-8000 catties, red skin and white heart, good taste, high retail price, good efficiency. This method can be carried out in the open air or in a greenhouse. The first is the accumulation of manure.

Cow dung and pig manure are used to pile up into a furrow of one meter to one meter and five wide, thick rice, and unlimited length, form a prismatic shape, level the top, spread a fine sand layer of five to ten centimeters, and then put the intact sweet potato seeds on top and row them upright.

Sweet potato is also called sweet potato in our place, it is one of the foods that people generally like to eat, sweet potato seedlings are a more troublesome thing, if the subject planting area is relatively small, you can not need to raise seedlings, to the planting season there are special sweet potato seedlings on the market, buy them back and plant them directly. Every year at the beginning of spring, that is, from the end of February to the beginning of March, the seedlings are picked out from the cellar and carefully selected for sweet potato seeds.

Whether it is an open field or an oil wheat field, the planted vines should be prepared in advance, the longer the vine, the better, the stronger the better, the good vine is easy to live, the sweet potato with a good vine is good, and the sweet potato with a long vine is big. If the cold air comes, then cover the two, and wait until the temperature rises and the weather is stable, you can remove all the film, and then water the farmer's fertilizer to reach the strong seedlings. Wait until there is a meter long Teng can be inserted, and generally cut 2 to 3 sections.

The cultivation time of sweet potato seedlings should be determined according to the planting area and climate, usually the cultivation time is concentrated in March, when cultivating in the spring, it is generally before and after the sting, the southern region can start to cultivate in February, and the northern region should complete the cultivation before the Qingming Festival. Because the temperature is low during cultivation, it is necessary to cultivate in a hot bed, during which it is necessary to do a good job of heat preservation measures, and it can also be reasonably grasped according to the time of planting and marketing, and generally start the cultivation work 4-5 weeks before planting sweet potato seedlings.

In fact, it is best to be in summer, because the sun in summer is also very hot, and sweet potato seedlings must go to the sun, and then there must be enough light and temperature to make it develop better.

The best time to cultivate sweet potato seedlings is spring, and I think it is best to cultivate sweet potato seedlings in spring, because spring is best for its growth and development.

In late winter and early spring, this is the best time to cultivate because the weather begins to warm up and is suitable for the growth and development of seedlings.

The best time to sow seeds in the north is in mid-May, when the temperature is basically stable at 15 to 20 degrees, and the sweet potatoes can germinate quickly.

Spring potatoes can be transplanted when the ground temperature is stable at 12 degrees, and around May 1 in North China; Summer potatoes are harvested immediately after the wheat harvest, around the beginning of June.

There are two times of the year that are ideal for growing sweet potatoes. The first period is between April 20th and May 10th, and after planting, the temperature is maintained above 15, and it can be harvested in about August-September, and the second period is from the 10th to 20th of June, and it is necessary to keep warm after planting, and it can be harvested in September-October. Except for the hot summer, it can be planted during the solar term, but it is necessary to avoid continuous rainy weather when planting, because such weather will reduce the number of sweet potato seedlings in stock and reduce the yield.

The timing of potato planting depends on the region. Preferring cool conditions, most areas are planted between October and December. If you are in the Tohoku region, it is best to plant between April and May.

Dear, hello, mid-April is the appropriate period for seedling planting, at this time the temperature warms up in early spring all year round and is basically stable, the appropriate period for planting seedlings is 10 cm after the end of the late frost when the ground temperature reaches 15 or more, you can start planting seedlings, last winter or early ploughing and whitening, and then ridge and furrow when planting. The furrow belt is 50cm wide, and the seedlings are cut and planted in early and mid-April according to the seedling speed of the seedbed, and the line is used to increase the number of seedlings into the soil to increase the number of potatoes. 3500 4000 plants are inserted per mu, and the plant spacing is about 33cm.

The planting time should not exceed April 20, otherwise the harvest time will be delayed, which will affect the transplanting season of continuous cropping late rice.

In spring, seedlings are generally raised in the southwest after the vernal equinox, around March, and seedlings are transplanted at the end of April.

Sweet potato seedlings generally start at the end of the first month, and the seedling period is about one and a half months to 50 days. Sweet potato seedlings are divided into modern and traditional rain seeds. Modern seedlings are seedlings raised in plastic greenhouses, which are hugged into a long furrow more than one meter wide like planting crops, forty centimeters deep, and a layer of virtual soil is padded at the bottom, and then sweet potatoes are placed, and then covered with soil on the top.

There are three methods of traditional seedling raising methods, namely: hot pool, cool pond, and earth pond.

Seedlings should be raised from February to April, about a month, you can use the potato tuber cultivation method, you need to choose fertile and loose soil, and the drainage must be good.

It takes about a month and a half for sweet potato seedlings to be planted.

Root seedling cultivation is also the most commonly used seedling method, seedling time will vary according to different places, but under normal circumstances, sweet potato seedling should be carried out between mid-February and mid-April, and the seedling time of spring sweet potato is in Huaihe.

The temperature in the south of the Huai River starts after mid-February, and the temperature in the north of the Huai River is slightly lower, which can be postponed to March to early April.

Mulching film breeding can be advanced, and open-bottom seedling breeding can be postponed, but it is more appropriate to raise seedlings before April 20. Sweet potato seedlings can be divided into two kinds according to different materials, one is to use sweet potato tubers for seedlings, and the other is to use sweet potato vines for seedlings, and the two methods of seedling raising have their own advantages and disadvantages.

Generally, sweet potatoes are raised before and after stinging. When raising seedlings, it is necessary to select sweet potato seeds with good varieties and no bad varieties, soak the sweet potato seeds with pesticides for 2-3 hours, and then dry them. Next, the row is carried out, as long as you grasp it, the large dense row, the small thin row can be.

This is good for management.

Sweet potatoes are generally raised before and after the sting. When raising seedlings, it is necessary to select sweet potato seeds with good varieties and no bad varieties, soak the sweet potato seeds in the agent for 2-3 hours, and finally arrange the seeds.

Sweet potatoes need to be the most suitable time between mid-February and mid-April, the temperature is best controlled between 5 and 25, not too high or too low, too high or too low will reduce the speed of sweet potato fry.

Every year at the beginning of spring, from the end of February to the beginning of March, the seedlings are carefully selected from the cellar and left for sweet potato seeds.

The older generation is engaged in farming, which is arranged according to the 24 solar terms, and the seedlings of sweet potatoes for spring ploughing are generally before and after the sting. However, depending on the climatic conditions, the seedling rearing time will be somewhat different, and as a rule of thumb, it is best to breed seedlings 45 days before planting. For example, breeding starts after mid-February in areas south of the Huai River, and finishes breeding in areas north of the Huai River before April 10.

Due to the relatively low temperature during this period, sweet potatoes are mainly bred by covering plastic film.

Cultivating sweet potato seedlings is best done in March-April each spring.

The temperature in March and April is about 15 degrees, and the light is relatively bright, which is conducive to the growth and germination of sweet potatoes, or to cultivate sweet potato seedlings in the greenhouse, the indoor temperature can be controlled between 15-20 degrees, so that the sweet potato seedlings grow vigorously.

When cultivating sweet potato seedlings, you need to prepare a shallow basin that has been sterilized, then pour water into the shallow basin, and then place the sweet potato in water, and the depth of the shallow water cannot exceed the sweet potato, and finally you can move the sweet potato to a ventilated semi-shaded environment, wait for a few days, and the sweet potato will sprout.

When planting sweet potato seedlings, you need to use a sharp knife to cut the sweet potatoes into small pieces, so that each sweet potato piece has 1-2 sprouts, and choose a sandy loam soil with good drainage, and then apply rotten farmhouse fertilizer to it to make the soil more fertile, and then you can plant the sweet potato pieces into the soil.

Precautions for planting sweet potatoes

1. The canopy is reasonable and dense, and the mausoleum is planted and weeded. Sweet potatoes should be planted appropriately and densely in the early stage of growth, and a certain amount of weans should be dug up in time as they grow in the later stage, and weeded regularly. This is good for root growth and bulb development.

2. Do a good job of land preparation and fertilization. Choose appropriate soil preparation methods to increase soil porosity, and apply an appropriate amount of organic fertilizer or compound fertilizer before planting. Sweet potatoes grow quickly and require high nutrients, and insufficient fertilization can affect yields.

3. Timely irrigation. During the growing season of sweet potatoes, especially during root growth and bulb expansion, timely irrigation is required to replenish water. However, it should not be too much, so as not to cause edema and root damage.

4. Regular inspection and prevention. Sweet potatoes should be regularly inspected during the growing season, and pests and diseases should be prevented and controlled in time. Sweet potatoes are more susceptible to aphids, codling moths and red bees, so it is necessary to choose control drugs that are efficient and harmless to humans and animals.

Hello April-May 1Sweet potatoes are suitable for planting in April and May every yearBecause the light time at this time is longer, and the temperature can be stable at more than 10 degrees, it is conducive to the growth of sweet potatoes Wangkuanling Mosheng, 3

When planting sweet potatoes, it is necessary to plough the fine soil, and then bury the sweet potato pieces that have been germinated and disinfected by Wang Sheng into the soil, and then cover with a layer of plastic film to promote the rapid emergence of sweet potatoes.
