Planting and Management of Potato

Potato, also known as potato and potato, is a kind of tuber edible annual herb of Solanaceae, so what is the planting and management of potato?

1. Basic introduction of potatoes

Potato is an annual herb of Solanaceae and Solanum, which is an important food crop. Potato tuber contains a lot of starch, which can provide rich calories for the human body, as well as other proteins and amino acids. It's a relatively healthy food.

The growth and development of potato can be divided into four stages: the dormant period of tuber, the germination period of seed potato, the growth and development period of plant and the formation stage of tuber.

The growth rate of potato tuber was the fastest about 20 days after flowering, and then with the gradual decline of aboveground stems and leaves, the nutrient input of potato tubers decreased accordingly, and the tubers did not stop growing until the stems and leaves completely withered.

II. Planting and Management of Potato

Select the potato varieties suitable for planting, determine the planting time according to the local climate, accelerate germination before sowing, and then cut into bud blocks for sowing. After potato germination, reasonable fertilization, watering, pest control and other management were carried out according to the growth of crops.

Kexin 6, Kexin 1, Shaza 15, Anshu 58, Anshu 56 and Taiwan Hongpi are all suitable for open-air cultivation.

Potato sprouting generally uses a mixture of 70% methyl topiramate 2 kg and 72% agricultural streptomycin 1 kg evenly mixed with 50 kg talc powder.

Seed potatoes should not be placed directly in the sun. Handle them carefully and handle them gently to prevent sprouts from breaking. Seed potatoes should be placed in a well-ventilated place to avoid rain and frost.

It is best to apply balanced fertilization (formula fertilization). When tubers yield 1000 kg per mu, it is necessary to absorb 5.6kg N, 2.2kg P and 10.2kg K from the soil.

Continuous cropping of potato is not suitable, because continuous cropping can aggravate soil-borne diseases and insect pests, easily cause serious lack of some elements in the soil, destroy the natural balance of soil microorganisms, increase the accumulation of harmful substances secreted by roots, and affect the yield and quality of potatoes. so it is best to rotate with rice, corn, onion, garlic, melons and other crops.
