Why does growing sweet potatoes without turning the vines give a higher yield?
I think everyone is very familiar with sweet potatoes. I remember when I was young, I often went to the fields with my grandmother to plant sweet potatoes. As I have grown older, the chances to work in the fields have become fewer and fewer, but I still eat sweet potatoes often. Growing sweet potatoes without turning the vines yield

High-yield cultivation method for sweet potato by cutting into pieces and direct sowing
In the cultivation of sweet potato by cutting into pieces and direct sowing, planting is carried out 20-30 days earlier than traditional planting. Because the growth period is extended, the yield of fresh sweet potato is generally increased by about 1000 kg per mu. It is a comprehensive high-yield cultivation technique with low investment, large returns, and savings in labor and time. 1. Prepare the soil early.

Because the growth period is extended, the yield of fresh sweet potato is generally increased by about 1000 kg per mu. It is a comprehensive high-yield cultivation technique with low investment, large returns, and savings in labor and time. </p><p></p><p>1. Prepare the soil early. In winter or early spring, open furrows and deep-plow 30 cm, which can increase soil temperature and water content, and use the low temperatures of winter and spring to kill overwintering underground pests and diseases. Form ridges along north-south rows or according to the terrain, with a ridge spacing of 60 cm and a ridge height of 20 cm. The ridge shape should be tall and plump, and the furrow should be deep and narrow, which is beneficial both for drainage and drought prevention and for root tuber expansion. When forming ridges, keep the ridge soil loose, and rake the ridge surface flat and firm. Apply sufficient base fertilizer: per mu, apply 4000-6000 kg of organic fertilizer, 50 kg of ammonium bicarbonate, 50 kg of superphosphate, 20 kg of potassium sulfate, or 100 kg of plant ash. </p><p>2. Carefully select seed potatoes. Choose excellent varieties suitable for local planting. The potato pieces should be uniform in size, and pieces of 100-150 g are better. Remove potato pieces damaged by freezing or pests and diseases. Generally, 50 kg of seed is used per mu. </p><p>3. Cut into pieces and soak the seed. According to the characteristic that the upper end of the potato piece has dense buds and the lower end has sparse buds, the upper part of the potato piece should be cut smaller and the lower part larger. Generally, each piece retains 2-3 bud eyes. Put the cut seed potatoes promptly into a 500-600 times carbendazim solution and soak for 10-20 minutes. The solution temperature should preferably be 5°C higher than the air temperature at the time. Remove, dry, and plant immediately. </p><p>4. Sow in time. The time for cutting into pieces and direct sowing is 1 month earlier than the time for transplanting seedlings. After the seed potatoes come out of the cellar, they should be handled promptly and sown into the field as soon as possible to avoid freezing damage. Before sowing, open a furrow 15 cm wide and 5-6 cm deep on the back of the ridge. After watering the furrow sufficiently and letting the water seep down, place the mother pieces in the furrow with the bud-eye side facing south and up, with a plant spacing of 25-30 cm. After planting, immediately cover with film to help preserve moisture and raise temperature, and promote sprouting. </p><p>5. Strengthen management. In the early stage, replant seedlings in time. When seedlings are about 2 cm high, promptly make holes in the film manually at the emergence points to avoid scorching the young seedlings. At the end of May and the beginning of June, when the soil temperature rises, remove the film in time. In the middle and late stages, pay attention to drainage and waterlogging prevention, protect stems and leaves, and do not turn the vines. Topdressing should not be excessive; foliar topdressing can be carried out. Spray 50 kg per mu of 1% urea or 0.5% potassium dihydrogen phosphate solution on the leaves. At the same time, pay attention to weeding and pest control.</p>

Five Key Points for Late-Stage Sweet Potato Management to Ensure a Bumper Harvest
After late August, summer sweet potatoes enter the critical period of tuber expansion. At this time, management should be strengthened. On one hand, the nutrients needed for tuber expansion should be met to the greatest extent possible; on the other hand, premature senescence of stems and leaves should be prevented, photosynthesis should be enhanced, and nutrient accumulation should be increased. Specific yield-boosting technical recommendations are as follows

How to grow sweet potatoes for higher yields? These four methods are very practical
For inverted planting, first cut off the top 2-3 nodes of the sweet potato vine, then cut it into sections of 4 nodes each, remove the petioles and leaves of the upper two nodes of each section, keep the petioles and leaves of the lower two nodes, and plant them upside down on the ridge, so that one petiole base is left exposed above the ridge surface

How to grow autumn sweet potatoes for high yield? Early planting is the key
Practice has proved that the yield of sweet potato is closely related to the growth of stems and leaves. Sweet potato is a warm-loving crop, and the hot and humid July to September is the golden season for cultivating autumn sweet potatoes. High-yield experience from various places has proved that timely early planting, extending the effective growth period, and increasing the effective accumulated

Growing sweet potato vines on trellises can increase yield
Last autumn, on the day we dug up the sweet potatoes, many onlookers came over, because they wanted to see just how the yield turned out after growing sweet potatoes on trellises. As soon as several piles were dug up, the onlookers were full of praise: the trellised sweet potatoes had grown really well, large, uniform, and abundant in yield!

Detailed Explanation of Key Techniques for High-Yield Cultivation of Hybrid Rice
1. Seedling Raising (Dry Seedling Raising Technique) 1. Seed treatment and germination acceleration: Before soaking the seeds, sun-dry them for 1-2 days, rinse with clean water, remove the empty and shriveled grains, and put the seeds in a nylon mesh bag. Then soak the seeds in a 500-fold dilution of 50% carbendazim wettable powder for 24 hours, take the seeds out, wash them clean with clean water

Rational application of booting fertilizer to rice for high yield
Rice cultivation is very common in our southern region, and the demand for rice in our country is enormous, but as more and more young people go out to work, more and more fields have been abandoned, resulting in the current state where rice cultivation in our country is far from meeting demand.

Key Points of Fertilizer and Water Management Techniques for High-Yield Rice Cultivation
In high-yield rice cultivation, the level of yield is determined by fertilizer and water application as the core; fertilizer and water application should be decided according to the fertilizer requirements of the variety, the level of soil fertility, the planting time, etc. Generally, 100 kg of paddy rice requires 2 kg of pure N, 1.2 kg of pure P, and 1.5 kg of pure K. The fertilizer and water application measures are specifically proposed as follows:
