What kind of the latest potato is good?

Potato is a perennial herb of Solanaceae, the fourth most important food crop in the world, second only to wheat, rice and corn, and has become the world's five largest crops along with wheat, rice, corn and sorghum. It is native to the Andes of South America. The history of artificial cultivation can be traced back to southern Peru from about 8000 BC to 5000 BC. Let's take a look at what varieties of potatoes are good!

Early and clear.

[characteristics] "Zaodabai" potato is a very early-maturing variety, with a growth period of 60-65 days. Tuber oval, white skin, white meat, smooth epidermis, good-looking tubers. Tubers are concentrated, and the rate of large and medium-sized potatoes (commodity rate) is as high as 90%. Good quality and palatability.

[yield] "Zaodabai" potato has wide adaptability and can be cultivated in the south and north of our country. It is suitable for cultivation with high water and fertilizer. Generally, the yield per mu is 1500 kg, and the high yield can reach more than 4000 kg.

[cultivation] "Zaodabai" potato uses virus-free seed potato and accelerates germination before sowing, and the planting density is about 4500 plants / mu. Because the tuber is concentrated, the tuber is large and the yield is high, so the planting technology should grasp the principle of "deep planting, shallow burying, covering soil for many times", and attention should be paid to the prevention and control of potato late blight during the growth period.

Super white

[characteristics] "Chaobai" potato is a very early-maturing vegetable variety, which was bred by Dalian Agricultural Science Research Institute of Liaoning Province. The plant grows luxuriantly and grows strongly, with a height of about 40 cm. The stem is green and stout, the leaf is fat and peaceful, and the leaf color is thick green. The flowers are white. Tubers are concentrated and tubers are round. White skin and white meat, large and neat, the rate of large and medium potatoes is 71mm 84%, the skin is smooth and the quality is good, and the starch content is 12.5% 13.4%.

[yield] "super white" potato is suitable for planting in the second-season planting areas and suburbs of Liaoning, Hebei, Jiangsu and Anpan, with an average yield of about 1500 kg per mu (1 mu).

[cultivation] the suitable planting density of "super white" potato is about 5000 plants per mu. In planting, it is necessary to strengthen management, timely irrigation and re-application of high-quality mature base fertilizer.

Zhongshu No. 2

[characteristics] "Zhongshu 2" was bred by the vegetable and Flower Research Institute of Chinese Academy of Agricultural Sciences using LT-2 as female parent and DTO-33 as male parent. The plant is of diffusive type, with a height of 50-70 cm and a stout main stem. The whole potato has 3-4 stems, and the stem is light purple-brown. The leaves are dark green. Corolla purplish red, orange-yellow anthers, more pollen, strong natural fruit, many flowers, large berries, many seeds. The tuber is oblate, the potato skin and meat are yellowish, the epidermis is smooth, the bud eye is shallow and so on.

[yield] "Zhongshu No. 2" tuber has good quality, starch content 1417%, vitamin C 100g fresh potato 80ml, reducing sugar content less than 0.2%, suitable for edible and processing. The growth period is about 50-60 days from emergence to maturity. The growth and development in the field is vigorous. The tuber is concentrated, the tuber is large and neat, there are 4-6 tubers per plant, the dormancy period is short, it can pass dormancy after 40 days, good edible quality and storage resistance. The general yield is 1500kg / mu to 2500kg / mu.

[cultivation] "Zhongshu No. 2" is suitable to be planted in winter in our area, and it can be planted densely, and the suitable plant is 4000mm / mu. In cultivation, the soil is required to have middle and high fertility, and the growing period requires sufficient fertilizer and water, which is not suitable for dry land cultivation and can be intercropped with other crops. Cultivation management is used to promote to the end, as an early-maturing vegetable cultivation.

Zhongshu 4

[characteristics] "Zhongshu 4" is a very precocious variety bred by the Institute of vegetables and Flowers, Chinese Academy of Agricultural Sciences in 1995. About 60 days after emergence and maturity. The growth potential is strong. The plant type is erect, the plant height is about 50 cm, the number of branches is few, the stem is green, and the base is lavender. Leaves dark green, compound leaves tall and straight, medium size, leaf margin spreading, Corolla lavender, can bear natural fruit.

[yield] "Zhongshu 4" tuber oblong, yellowish skin yellowish flesh, smooth epidermis, large and neat, few and shallow bud eyes, concentrated tubers. The dormant period of tuber is about 60 days, it is resistant to barren and has excellent steaming quality, with a yield of about 1500 kg per mu.

[cultivation] "Zhongshu 4" 4500000 plants per mu. Sprouting before sowing, applying basal fertilizer, strengthening early management, cultivating soil and ploughing in time, promoting early planting, early tuber setting, timely irrigation during tuber setting and tuber expansion period, and horizontal irrigation one week before harvest to facilitate harvest and storage. It is suitable for intercropping with cotton, corn and other crops.
