How many jin of potatoes can about one mu produce, and how to plant them for high yield?

The potato is the potato, a common vegetable in daily life, grown in all parts of our country, and the current market conditions are relatively good, so the planting prospects are still good. So how many jin of potatoes can about one mu produce? How to plant for high yield?

I. Introduction to potatoes:

1. What varieties of potatoes are there?

Potato varieties include Zhongshu No. 3, Zhongshu No. 5, Dongnong 303, Favorita, Kexin No. 1, Xishu No. 1, Jinshu No. 2, Atlantic, Shepody, Mira, Weishu No. 1, Qingshu 168, Jinshu No. 7, Xiangshu No. 10, Longshu No. 3, Dongnong 303, Kexin No. 4, Weiyu No. 3, etc., among which Zhongshu No. 3, Zhongshu No. 5, Dongnong 303, Favorita and Kexin No. 1 are mostly used as fresh potatoes for eating.

2. Can sprouted potatoes be eaten?

It is best not to eat potatoes once they have sprouted, as it may cause poisoning. Fresh potatoes contain a trace amount of solanine, which is not harmful to the human body, but during long storage the solanine content gradually increases. When potatoes turn green, sprout or rot, the solanine content increases greatly. After sprouted potatoes are treated by removing the sprouts, the green tuber may still retain solanine, which can also cause poisoning, so sprouted potatoes are not suitable for eating.

II. How many jin can about one mu of potatoes produce?

Generally, the normal yield of potatoes per mu is around 3000-5000 jin. If the yield per mu is above 8000 jin, it counts as a high-yield potato crop. Moreover, potato yield is affected by many factors, such as variety and planting method. Potatoes like slightly acidic soil and fear alkaline soil. The suitable pH value should be controlled at around 6.0. If the soil is alkaline, its yield will be reduced.

III. How to plant potatoes for high yield?

1. Seed selection: how to choose?

Potato varieties should be selected according to factors such as the planting environment, time and weather, and market demand and season should also be considered. As long as varieties are selected according to these conditions, a very good yield can be obtained.

2. Raising seedlings: how to raise seedlings?

(1) Selection of seed potatoes: choose disease-free medium-sized potatoes with relatively even eyes for sprouting.

(2) Treatment of seed potatoes: after cutting the selected seed potatoes, dry them, place them in a relatively shady place, spread a layer of moist sand, then cover with plastic film to keep warm. Generally, within 1-2 weeks the eyes of the potato pieces will begin to sprout. Sow those that have already sprouted, and continue forcing the ones that have not yet sprouted.

3. Sowing: how to plant?

(1) Soil requirements: potatoes grow faster in the later stage, so the soil for planting potatoes must be fertile, deep and relatively soft. The drainage system should be good.

(2) Sowing method: divide and prepare the land into field beds in rows, with the field beds 70-80 cm wide and 30-40 cm high. Different field beds should mainly be chosen according to the variety, and the planting density should be reasonably controlled. Generally the distance between each hole is about 25 cm, and the row spacing is 30 cm. And because the growth period of potatoes is relatively shorter than that of other crops, its fertilizer requirement must be guaranteed.

4. Temperature requirements: how many degrees is best?

Potatoes have a relatively large demand for light, but they are quite strict about light and temperature. During the potato seedling stage, 20 degrees is the most suitable temperature. The temperature for potato tuber growth should be controlled at around 18-20 degrees. Being higher than 20 degrees or lower than 18 degrees will have different effects on the growth and development of potatoes. For example, according to the weather and farming conditions in the south, sowing begins around the Beginning of Autumn, harvesting can begin in November, and after harvest winter sowing begins, with harvesting possible around the Beginning of Spring the following year. And so on by analogy. Spring sowing can be harvested in May-June.

The above is a related introduction to how many jin about one mu of potatoes can produce and high-yield planting methods. I hope it is helpful to everyone.
