Through a lifetime of growing sweet potatoes and potatoes, three secrets to a good harvest have been summed up
Introduction: Sweet potato and potato are favored crops, and there are many factors that need to be paid attention to in planting and management. The secret to high yields lies in the choice of soil, fertilization methods, plant growth control and timely watering.
Choose the right soil to increase yields.
Soil quality is the basis for growing sweet potatoes and high-yielding potatoes. The soil in which these two crops are grown is very demanding on soil quality. First of all, loose, aerated soils are the most suitable choice, especially sandy soils. Conversely, hard, compacted or heavy soils can directly affect the growth and expansion of potatoes, and even affect their taste. In addition, low-lying and waterlogged-prone soils are not suitable for growing sweet potatoes and potatoes. Therefore, in order to achieve high yields, we must choose loose, fertile soils that are not easily flooded.
Scientific fertilization promotes growth.
Sweet potatoes and potatoes need to be fertilized moderately during the growth process, but the form and choice of fertilizer must be scientifically considered. First of all, surface fertilizer is an indispensable step in the growth process of sweet potatoes and potatoes, and the way of fertilization has a lot to do with surface fertilizer. In the case of sweet potatoes and potatoes, too much nitrogen fertilizer, especially urea and ammonium carbonate, should not be used in the bottom fertilizer stage. This is because these fertilizers contain a lot of nitrogen, which can easily lead to stunted potato growth. Instead, nitrogen, phosphate, and potassium fertilizers should be applied in reasonable proportions to promote root growth and nutrient uptake, as well as provide adequate nutrients to plants.
Secondly, during the tuber formation period of sweet potatoes and potatoes, it is easy to cause malnutrition due to the high demand for fertilizer. At this time, it is very important to replenish fertilizer in time. It is mainly supplemented with nitrogen fertilizer and potassium fertilizer, which can be irrigated or irrigated with well-rotted manure and grass ash water. In addition, while watering, you can also use 03% potassium phosphate monobasic and 0Foliar sprays of 2% urea mixture were applied to improve nutrient use efficiency and absorption.
Through scientific fertilization, we can provide sweet potatoes and potatoes with the right nutrients**, improve plant disease resistance and growth and development rates, resulting in higher yields.
Control plant growth and increase yields.
Controlling the vigor of sweet potatoes and the growth of potato plants also plays a crucial role in achieving high yields. During the planting process, many people have a misconception that the better the plant grows, the more potatoes will be in the underground part. However, this is not the case. When the plant grows too vigorously, nutrients are used first for the growth of branches and leaves, resulting in slow potato development and difficulty in reaching a vigorous growth state, thus reducing yield. Therefore, in the middle of plant growth, controlling vigorous growth is the key to ensuring high yields.
There are many ways to control plant growth, such as flipping sweet potato vines, removing potato sprouts, and spraying doxorubicin. Flipping a sweet potato vine involves reducing nutrients** by lightly mulching the vine, allowing it to take root and inhibit its growth. Potato bud removal involves removing part of the flower bud when the potato bud begins to form to reduce the plant's growth intensity. Spraying paclobutrazol is a plant growth regulator, which can effectively inhibit the vigorous growth of sweet potatoes and potatoes, so that more nutrients are distributed to potatoes and promote the growth and development of potatoes. By controlling plant growth, nutrients can be fully utilized, increasing the yield and quality of tubers and achieving high-yielding crops.
Water promptly to maintain humidity.
Although sweet potatoes and potatoes do not like a lot of water, it is still necessary to water them in a timely manner when the soil is dry. Water is an important medium for absorbing nutrients, and if the soil is short of water for a long time, nutrients cannot be effectively absorbed, thus hindering the growth and development of sweet potatoes and potatoes. Therefore, if the soil is dry, it must be watered in a timely manner.
Summary. Choose loose and aerated soils, such as sandy loam, and avoid hard, brittle, and clay soils to ensure the development and taste of the tubersScientific fertilization, reasonable combination of nitrogen, phosphorus, potassium fertilizer, timely fertilizer supplementation, to meet the nutrient needs of sweet potatoes and potatoes;Control plant growth, take measures such as turning vines, removing potato buds, spraying paclobutrazol and other measures to improve the yield and quality of potato piecesWatering at the right time. When the soil is dry, water appropriately to keep the soil moist, stop watering before harvesting, and let the potato pieces gradually dry, which is conducive to soil removal and storage.
If we pay attention to these points and combine them with actual cropping management, we can help sweet potatoes and potatoes achieve higher yields and quality.
