Planting corn in the ground is still somewhat empty, if then planted with sweet potatoes, but also to improve the economic benefits it, in addition there are some benefits, growers can also understand, the next small talk about corn and sweet potatoes planted together with the four major benefits.
Corn and sweet potatoes planted together with the four major benefits:
1, mutual benefit
Use of the two own growth characteristics of mutual benefit.
In the sweet potato just cuttings when corn seedlings for sweet potato seedlings to shade the sun, practice has proved that the survival rate of sweet potato planted in the corn field is much higher than simply planted sweet potato field.
And the sweet potato vine grows well and completely covers the ground, occupying the space where other weeds grow.
Corn fields planted with sweet potatoes generally require less weeding.
In addition, sweet potato vines also have the effect of maintaining soil moisture.
The ground where sweet potatoes are planted is less prone to sloughing because raindrops can't fall directly onto the ground.
By the sweet potato leaves to block a little and then flow to the ground, it is not easy to make the soil crust.
2, double the economic benefits
I say double the economic benefits is modestly speaking.
The value of sweet potato vines alone is not less than that of corn.
The sweet potato vine is very rich in nutrition.
It is a pasture grass with excellent palatability.
Pigs, cows, sheep and even fish like it.
It can be said that one acre of sweet potato vine feeding effect is not inferior to one acre of corn.
Sweet potato is a very high yielding crop.
An acre yield of several thousand pounds is normal.
Sweet potatoes are widely used can be fed directly to livestock, can be used as raw material for starch, some varieties can also be sliced and dried to sell.
Slightly processed acreage of sweet potato produces much higher benefits than corn.
3, reduce labor intensity
Corn heavy nitrogen fertilizer, sweet potato heavy potash.
Fertilizer time is also very good to grasp.
The main farmyard fertilizer, corn a foot high can insert cuttings sweet potato seedlings.
To the corn now days flower chasing the tassel fertilizer just when the sweet potato into the expansion period, this time to nitrogen fertilizer potash-based fertilizer.
After the corn harvest, you can spray a low concentration of potassium phosphate according to the growth of sweet potato vines.
The two crops fertilization time almost completely overlap, a fertilization tube two crops is not a great reduction in labor intensity.
4, maximize the use of space
Corn and sweet potatoes a high and low reasonable space with the space can be maximized use.
Sweet potato vines are generally covered in the ground growth will not climb up will not affect the growth of corn.
And the corn foot leaves are more sparse, the pole is high, leaving plenty of room for the sweet potato vine to grow.
From the above, we can also understand that if you plant sweet potatoes in the corn field, but also be able to mutually beneficial, to play their respective advantages, so that the yield increased, the quality is also up, or very good.
