When is the best time to start digging potatoes

When the leaves of the potato as a whole begin to yellow, the stem and branch can start digging the potato when it is some wilting, because the leaf is yellow and can not photosynthesize, the stem and branch withering can not transport nutrients, at this time the potato in the soil can not get the nutrient supplement on the ground can be dug out in time, if not digging at this time it is easy to cause rotten bulbs or germination and easy earthworms to eat or rodents to destroy.

After flowering, the flowers slowly wither and when some small fruits grow, it is best to dig up. But you can only dig if the land is dry on a sunny day, otherwise the potatoes will rot easily.

Brief introduction.

When the potatoes grow and mature, they can be harvested, that is, when the stems and leaves begin to turn yellow and wither, its stolons will dry out and shrink, and will also separate from the tuber, at this time the tuber has stopped growing and gaining weight, and it is more suitable for digging.

Don't dig too early, otherwise the tubers are not mature enough, not only are they susceptible to bumps, but also the yield will be reduced, and if they are harvested too late, they may cause pests, diseases and frost damage.

Potato from planting to the leaf stem yellowing tuber terminates swelling picking, according to the early, medium and late maturing varieties are different, generally 90 120 days, in other words, mature varieties in about 90 days, late maturing varieties need about 120 days, like our Gansu Province a season cropping area, more planting in late maturing varieties, long growth period, in the tuber expansion period, can bypass the scorching heat and continuous high temperature hazards, into the autumn, the temperature difference increases, cassava starch and protein content increases, tubers expand rapidly, large production is high, Therefore, we cultivate a variety of mid-late maturing varieties in the open field, and the growth period is relatively long, nearly 4 months.

Potatoes are harvested gradually before the beginning of autumn cold dew, from gradual planting to harvesting generally about 130-140 days, it is the seedlings and yellow for the potato to be perfected, and the potatoes are dug and followed by the autumn wind and the season, and the autumn and winter wheat are planted. Make the walnut skin coarse out of the rice rate, one hundred catties of corn starch 19-21 catties up and down.

The pregnancy characteristics of mature potatoes are that it takes about 90 days from planting to harvesting, 60 to 70 days from budding to acquisition, and about 80 days from planting to obtaining for extremely mature varieties, and 50 to 55 days from budding to acquisition.

The key varieties of mature potatoes like this are, Yu Potato No. 1, No. 2, Fei Ruita, alias Spain No. 7, Spain No. 15, etc., Zhongshu No. 3, No. 4, No. 5, Zaoxiaobai, Tebai, etc. Mature potatoes have a short growing period and are suitable for planting in many locations. The two-season cropping area in the Central Plains, the one-season cropping area in the northern region, the two-season cropping area in the southern region, and the mixed cropping area in the southwest region can all be planted.

The growing period of autumn potatoes is 90 120 days from planting to harvest, and about 80 days from budding to harvest. It can be divided into medium-mature varieties from 90 to 100 days from the start of sowing and about 70 days from budding to acquisition. Medium and late ripening is harvested from the beginning of 110 to 120 days, and from budding to harvesting about 90 days.

It is rich in vitamins B 1, B2, B6 and acid reflux, as well as a lot of high-quality fiber, as well as nutrients, carbohydrates, proteins, lipids and trace elements such as high-quality tapioca starch. People who eat potatoes often are physically and mentally healthy, and they age slowly. Potatoes have a good role in caring for ** and maintaining appearance.

Fresh potato juice is immediately applied to the face, and the whitening effect is very obvious. It is very easy for people to be sunburned and tanned on a sweltering summer day, and potato juice has an obvious effect on eliminating pigmented spots, and there is no ***. However, the same is planted mature or late maturing varieties, the planting mode is not the same, so it grows and develops for a long time is not the same, if the choice of plastic film cover planting, because of the agricultural film of temperature insulation and heat preservation, solid soil drought tolerance effect, the same time for planting, but the time will be ten days and a half months earlier.

Potatoes can be dug up after three months of planting. The growing period of potatoes is relatively short, and some varieties will mature in less than three months. In addition, its ripening time is also affected by the region where it is cultivated, and the ripening time varies from region to region, but the growth cycle is mostly between 3 and 4 months.

When you notice that the stems and leaves of the potatoes are starting to turn yellow and the stolons are slowly drying up, it's time to dig up.

The growth period of potatoes depends on what variety, the general growth cycle of early-maturing varieties is about 60 days, medium-ripening is about 80 days, and late-maturing varieties are generally about 100 days. Potatoes are generally planted and can be dug up three to four months after planting.

The growing season of potatoes is usually 90 to 120 days. Normally, after sowing, it takes about 90 to 100 days to harvest the late-maturing potatoes, and it takes about 110 to 120 days from sowing to harvesting.

The growth period of potatoes is generally about 90 days, and some potatoes can even grow for about 130 days; When the potatoes finally arrive in the field, it generally takes about three months to be ready for use, and the potatoes are divided into three mature varieties in the morning, noon and evening, as long as it bears potatoes, it can be eaten.

Generally, it is about 60 days, and after recharging into the ground, it can be dug out in about 60 to 100 days, and the time for early-maturing varieties is relatively short, and the time for late-maturing varieties is relatively long.

The growth cycle of potatoes is generally about five months; Some early-maturing varieties can be dug up and eaten in about 3 months.
