The growth process of sweet potatoes, the growth process of sweet potatoes

First buy sweet potato seedlings, then the roots of the sweet potato seedlings, dip them in mud, and then take the good sweet potato seedlings to the ground, plant them under the wheat, and wait for the wheat to be harvested after the sweet potato growth period, and when the frost falls in the autumn is the time to harvest the sweet potatoes, put the thrown sweet potatoes into the cellar.

In the soil where sweet potatoes grow: sandy soil is appropriate, like potatoes and yams, because such soil grows out of the rules, clay soil is not suitable, which will affect the growth of tubers.

Environmental requirements for the growth of sweet potatoes:

1.Temperature-loving, avoid low temperature frost, the growth period needs more than 120 days of frost-free period.

2.Soil moisture suitable for growth is generally 60% to 80% of the maximum water holding capacity3For short-day crops, sufficient sunlight is conducive to root formation and expansion.

4.The soil is well permeable and well drained.

1. It is generally recommended to choose soil as the cultivation substrate, if it is inconvenient to take the soil, you can also use fillers such as sawdust, and the non-soil cultivation substrate has higher requirements for fertilization and management.

Sweet potatoes prefer fertile and loose soils, especially sandy soils, so that the sweet potatoes grown look good, so try to choose humus from woods or dense grasses, or sandy soil with high fertilizer efficiency. Sandy soils can also be obtained by mixing fertile and safe silt with fine sand.

2. After installing the soil, it is time to choose the appropriate placement. The main component of sweet potatoes is starch, which requires a lot of light to be conducive to potatoes, so the container must be placed on a sunny roof or balcony, otherwise the light will not produce potatoes or not produce potatoes enough. In addition, there should be enough space for the potato vines to climb.

3. Fill the bottom of the container with base fertilizer before planting, and put a few compound fertilizers in the middle and upper parts. When planting, the potato seedlings are laid flat and buried 5 cm deep under the soil, exposing two or three bud nodes on the ground.

After planting, water once a day in the morning and evening for a week; You can also move the pot to a shady place and water it every day or two. After a week, you can water the soil as it becomes wet or dry. After two weeks, if the growth is weak, it can be topdressed once; If the growth is good, there is no need for top dressing.

After planting for a month, you can fertilize it once, and finally wait for the harvest!

How much do you know about sweet potato aliases:

Sweet potato (English: sweet potato), scientific name: sweet potato (Ipomoeaa batatas (L.).

lam.Also known as sweet potato, red taro, sweet potato, sweet potato, sweet potato (northern), red potato (many local dialects), thread lotus, white potato, golden potato, sweet potato, red potato, pillow potato, kudzu, white taro, fennel sweet potato, red sweet potato, cute sweet potato, etc.

The sweet potato growth cycle is 160 to 200 days in spring and 110 to 120 days in summer.

The growth cycle of sweet potatoes varies depending on the time of planting, with the growth cycle of sweet potatoes in spring being about 160 to 200 days, while sweet potatoes in summer are generally 110 to 120 days.

According to the growth characteristics of sweet potato, the growth of sweet potato was divided into four growth periods: rooting and seedling stage, branching and tubing stage, full leaf stage, tuber expansion and stem and leaf decline stage.

Precautions for planting spring sweet potatoes

1. Time: When spring sweet potato cuttings, the temperature is low, so choose a sunny day for cuttings, do not take cuttings on rainy days, so as not to cause frost damage or root rot;

2. Cutting method and depth: Cuttings spring sweet potato, there are many varieties, such as starch type, fresh food type, etc. Starchy sweet potatoes can be inserted straight, obliquely and flatly, but fresh sweet potatoes need to be inserted flat.

The size of the sweet potatoes in the direct broadcast and oblique inspection is different, while the sweet potatoes in the flat insertion have a small difference in size due to the uniform absorption of nutrients.

3. Before and after cuttings, it is not easy to apply chemical fertilizers, but you can sprinkle rotten soybeans and so on in the hole; At the same time, it needs to be watered in moderation.

4. The depth of cutting: Sweet potatoes are clumped, generally less than 5cm in depth. Therefore, no matter which cutting method, the depth can neither exceed 5cm, nor shallower than 4cm, and it is also prone to drought if it is too shallow.

Introduction to sweet potato growth.

Sweet potato is suitable for growing in deep soil, loose soil, and soil with a pH value in between. At present, there are planting in the north and south of China, and the hidden jujube is mainly distributed in Anhui, Northeast, Henan, Hebei, Hunan, Hubei and other regions.

Sweet potato growth cycle.

Sweet potatoes are warm and cold-resistant, have strong transpiration, need more water, like light and warmth, are not shade-tolerant, have strong adaptability to soil, and have good acid and alkali resistance. The growth cycle of sweet potatoes grown at different times is also different. The growth cycle of sweet potatoes planted in the spring is about 160-200 days, and those planted in summer are usually 110-120 days.

From 010 to 1010, the growth process of sweet potato can be divided into four growth stages, namely, slow rooting stage, branching and fruiting stage, stem and leaf vigorous stage and stem and leaf decline stage. Sweet potatoes grow relatively fast and can be harvested 160-200 days after sowing.

Sweet potato growth rate.

Under normal circumstances, the yield of sweet potatoes is about 6,000 catties, and if you plant well, 8,000-10,000 catties are also available. Usually, the yield per mu will vary depending on the planting price, variety, management technology, region and other factors.

Sweet potato growth cycle management.

When the temperature is 25-28, the sweet potato stems and leaves grow rapidly. When the temperature is above 30, the stems and leaves grow faster, but the tubers expand more slowly. In general, tubers expand more quickly at 20-25 ground temperatures, but more slowly when they are below 20 or above 30.

Temperature management. After sweet potato enters the late stage of growth, the root absorption capacity is weakened, and foliar fertilization can be classified. Generally, a mixture of urea and potassium dihydrogen phosphate is sprayed every 7-10 days, a total of 2-3 sprays. The best time to spray is a sunny evening.

Fertilization management.

1.The growth cycle of sweet potatoes varies depending on the time of planting.

2.The growth cycle of spring planting is relatively long, about 160 days to 200 days, while the growth cycle of summer planting is slightly shorter, about 110 days to 120 days.

3.Its growth period is mainly divided into rooting and slow seedling stage, branching and potato grafting stage, full leaf stage and potato swelling stage.

<> sweet potatoes have a certain drought tolerance, the demand for water is not high, it is enough to keep the soil moist when planting, sweet potatoes are not cold tolerant, it is best to plant sweet potatoes in spring and autumn. So, how long is the growth cycle of sweet potatoes?

The growth period of sweet potatoes is about 160-200 days, which is related to the variety and planting time. For example, the growth cycle of spring planting is relatively long, about 160-200 days, and the growth cycle of summer planting is slightly shorter, about 110-120 days. Its growth period is mainly divided into rooting and slow seedling stage, branching and grafting stage, full-leaf oak mountain closing stage and tuber expansion stage.

<> sweet potato is a high-yield and adaptable food crop, and the roots, stems and leaves are excellent feed. The cultivation process of sweet potatoes is described as follows:

Choose sandy soil with good porosity and strong air permeability, apply sufficient base fertilizer after deep turning, and prepare for planting. After cutting the healthy sweet potatoes with no insect eyes into small pieces, plant them on the ridge according to the plant spacing of 30-60cm, cover the thin soil, apply sufficient fertilizer, and cover with film. After it germinates, do a good job in water and fertilizer, soil cultivation, and cultivation management.
