How is sweet potato cultivation high? Sweet potato high quality and high yield planting technology
Sweet potato is one of the grains that people often eat in people's lives. With the current awareness of health care, the market for sweet potatoes is much better than before. So how can sweet potato cultivation achieve high yields? Let's take a look at the high-yield cultivation methods of sweet potatoes.
First, choose high quality potato seedlings of excellent varieties
High-yield sweet potatoes are inseparable from high-quality potato seedlings first. High-quality sweet potato seedlings can increase yield, early potato production, and strong disease resistance. High-quality sweet potato seedlings generally have short internodes, three to five knots, and seedling heights of 20 to 30 cm.
Second, promote ridge cultivation
Small ridges are generally cultivated in a single row. The ridge distance is 70 cm and the ridge height is 15 to 20 cm. The large ridge is double-row cultivation. The ridge distance is 85 to 95 cm, and the ridge height is 25 cm.
Third, pay attention to the application of potassium fertilizer
As a variety of high-yielding crops, sweet potatoes have a lot of demand for fertilizers, among which potassium is the most demanded. The principle of fertilization of sweet potato is mainly potassium fertilizer, moderate nitrogen fertilizer, potassium and phosphorus.
Fourth, the use of mulch film early planting
It is possible to plant the mulch at an appropriate time, which can prolong the growth period of sweet potatoes and increase the accumulation of nutrients.
Fifth, improved horizontal planting
The improved horizontal cutting is to increase the number of sweet potato seedlings into the soil, and the number of nodes in the potato is also increased, so that the consumption of nutrients and water will be less, the time for slowing down will be shorter, and the survival rate of planting will also increase.
Method introduction: first digging the sweet potato seedlings, then pouring the water, and then inserting the sweet potato seedlings. After the sweet potato seedlings are broadcasted at a depth of about five centimeters, they are buried flat, and the thickness of the covering soil is about five centimeters. Remember to expose the top three leaves.
The above is the main point of high-yield cultivation of sweet potatoes. What do you think? What else can be added? Welcome friends to leave a message. If you still want to learn about the cultivation techniques of other grains, you can continue to pay attention to the Hui Nong School!
