Shandong is the province where the potato is grown, especially in teng county, where the potato is quite famous. A lot of friends ask me, how can i grow a big skin and high-yield potato? As an old-fashioned grower, today i'm going to tell you about this "sundong model" of dry planting
1. Cultivation time: early or late
In our shandong, spring potatoes are usually stuck around "frightful," in the middle of march. It's time for the temperature to rise and stabilize and plant. Remember not to be too late, otherwise the potatoes have not yet reached high temperatures and are easily reduced。
Selection: good seeding
Don't plant the potatoes directly from home. You have to choose the detoxicated potatoes, like holland 15 and lutz 1. Picking chips is complete and bright. When cutting a piece, remember to disinfect the cutter, to finish a bit of grasswood ash or polybacterium, and to “seal” the wound to prevent the rotten seed。
3. Cultivation requirements: land laxity
Potatoes are the toughest. They have to choose sandy soil, which is thick and thin. The whole of the land is covered by the base fattening of a grown farm, a “gas station” of potatoes. Cultivation is the key, and the higher the sodium, the smoother the potatoes grow, and it is not easy to be green。
Field management and prevention: care is key
It's not that bad. In the current period, the buds must be removed so that they do not waste their nutrients, which is called "cracking potatoes". The water is “dry and wet”。
It's about disease prevention and treatment: we've got a small infestation in shandong spring, but it's the worst in the world. Once water stains on the edges of the leaves are found, they are sprayed once every seven days, twice or three times with dysen-manganese zinc or mercantile manganese zinc, otherwise the area becomes obsolete. The pests are mainly aphids and subterranean insects, with a few venomous granules sprayed at the onset, while more aphids were sprayed with abdominal insects and used to save heart。
5. Harvest: ignorance
And when the plants turn yellow and weary, that's the sign that the potatoes are ripe. Pick a clear day to dig, not after the rain. Dig it out a little bit to dry the skin, so don't get tanned so the potato skin can turn green。
If we do this, this year's potatoes will pile up! See you in the problematic area
