How many kilograms of sweet potato yield per mu is the highest
A small knowledge of experience, introducing you to the highest yield of sweet potatoes per mu, green plant maintenance tips, specifically as follows:
How many kilograms of sweet potato yield per mu is the highest
Generally speaking, the yield of sweet potatoes is about 2000-3000 kilograms per mu, the yield of sweet potatoes planted in spring is about 3500 kilograms (7000 jin), and the yield of sweet potatoes planted in summer is about 2500 kilograms (5000 jin). The specific yield of sweet potatoes may be affected by factors such as variety, climate, planting techniques, and planting time. To obtain a higher yield of sweet potatoes, it is necessary to master the correct planting techniques.
How many kilograms of sweet potato yield per mu
Sweet potatoes, also known as sweet potatoes, generally have an output value of 2000-3000 kilograms per mu, with high yields reaching 4000 kilograms. In fact, if more effort is put into soil quality, fertilization, and management, it is still possible to achieve a yield of 5000 kilograms (10,000 jin) per mu.
The yield of sweet potatoes is related to the planting season and variety. Sweet potatoes planted in spring yield about 3500 kilograms (7000 jin) per mu, and sweet potatoes planted in summer yield about 2500 kilograms (5000 jin). Additionally, there are many types of sweet potatoes, such as white sweet potatoes and watermelon sweet potatoes, and there are differences in yield between different varieties.
High-yield planting techniques for sweet potatoes
Sweet potatoes prefer warmth and fear cold, and planting should ensure a certain temperature. If the temperature is not suitable, it will affect the growth and development of sweet potatoes, leading to reduced yield. The following specifically introduces how to plant sweet potatoes for higher yield.
Select a suitable planting siteGenerally speaking, the yield of sweet potatoes is greatly related to the soil. Sweet potatoes prefer deep, loose, and well-drained sandy loam soil, and it is best not to have continuous cropping, with the previous crop not being sweet potatoes.
Deep plowingWhen planting sweet potatoes, the general plowing depth is 25 centimeters, but if you want high yields, you need to plow to a depth of about 35 centimeters. Deep plowing can enhance soil aeration, help retain water, and promote the downward growth of sweet potato roots, which can strengthen drought resistance and flood resistance.
Ridge cultivationIf you want to increase the yield of sweet potatoes, ridge cultivation is also a point to note. Ridge cultivation can increase yields by about 20% compared to ordinary cultivation. It is recommended to have a ridge height of 30-35 centimeters and a ridge spacing of 70 centimeters, with two rows per ridge and a plant spacing of about 30 centimeters.
Scientific fertilizationFertilization also has many precautions, and not all fertilization can achieve high yields. Choosing the right fertilizer is key. Fertilization generally focuses on base fertilizer, which usually accounts for 80% of the total fertilizer.
I provide a plan for everyone to refer to: Apply 3500 kilograms (7000 jin) of decomposed manure, 35 kilograms of superphosphate, 30 kilograms of ammonium sulfate, 25 kilograms of potassium sulfate, and 2 kilograms of zinc sulfate per mu. However, the amount of nitrogen fertilizer used needs to be determined based on the fertility of the soil.
Smart topdressingIn the middle and late stages of sweet potato growth, the tubers begin to expand, and potassium fertilizer should be used as the main fertilizer for root irrigation at this time. You can use 1% potassium dihydrogen phosphate at 200-300 kilograms per mu in late August. At the same time, you can spray potassium dihydrogen phosphate foliage fertilizer every 15 days during planting.
The above is the related explanation of how many kilograms of sweet potato yield per mu is the highest, hoping to bring a little help to your life!
