The old saying, "screech, clear and clear," makes sense, but the story of growing potatoes cannot really look at the calendar. I've seen too many farmers, suffocated on the same day, and the harvest is very different. The real secret is not the moon placards on the wall, but the breathing of the soil below your feet and the changes in the sky。
It's too early for a seedling to catch a “spoiling cold” and can freeze overnight; it's too late to grow, and the potato swells directly into summer heat, small and ugly. Today, let's talk about how to grab the best seeding window that's ever gone。
Why is “time” a lifeline for potatoes
The potato thing, the sex thing, it's kind of "porn." it's life, and the temperature is round and round. From a piece of chips to the harvest of a basket of fruit, three temperature gallons must cross。
The first canton is the "awaken seed temperature." potatoes have a “physical hibernation period” and require appropriate temperatures (7-8°c) to be “awakened” to germinate. The soil is too cold, it sleeps and rots in the earth long enough; it is too hot, it is thin, it is innate。
The second canton is "the temperature of a seedling." when it's full, it's freezing. It takes a long time to regenerate the plant and to delay growth at a later stage. So, planting is a good day, and the seedlings are perfectly safe from the last frost。
The third canton is the soccer temperature. This is the most critical link. When the potato trachea starts to expand, the favorite temperature is 17-19°c. If the weather is too hot at this time (over 25°c), it is “negatively underworked”, slowly growing and small. The planting date must therefore be reversed to ensure that the potato season falls in a cool season。
Two: how do you judge it? Look at the sky, the two signals are the best
What do you think? Remember two “natural signals” better than the calendar。
First signal: look at the temperature, not just the temperature. Many people used to watch weather forecasts, but seeds were buried in the ground. The correct approach is to measure soil temperature at about 10 a. M. Deep below ground. When the temperature stabilizes over 7-8°c for 5-7 days in a row, it is the seeding signal. An earthly method: holding a piece of earth with a hand, squeezing it into a mass, and falling into the ground. This humidity is good with the right temperature。
Second signal: look at objects, nature's timer. It's the wisdom of the elders. Watch the plants around you:
Iii. Distribution: a national planting time map
Our country is vast, ranging from south to north, and the timing of seeding varies considerably. It can be broadly divided into three main war zones:
1. Quarter north (north-east, north-west, etc.)
It's cold here, and it's just a one-strike a year. At the core is the "jacking". In late april and early may, when the soil is frozen and the ground is warm enough to reach the target, it will be necessary to raid and sow the seeds. The goal is for potatoes to grow in a cool summer and harvest before fall frosts fall. Remember not to be greedy and avoid freezing。
2. 2nd quarter of china (north china plain, etc.)
It's an art area that's growing, and it can grow in spring and autumn. Spring sowing took place in the middle of march, with membrane cover available early until the end of february. The core contradiction is the pre-late cream, which later avoids high temperatures. In the fall, around early in august, the core was post-breeding to ensure maturity before the frost。
3. Southern winter zones (twice, fujian, etc.)
Using warm winters, seeds were planted between the end of october and november. The core is “dive”, avoiding the final high temperature of the tiger in the autumn, leaving the potato season at its coolest winter. Potato seeding after rice is an efficient planting pattern here。
Iv. My experience: three details that have significantly increased success rates
In addition to timing, a few little tricks can make you grow twice as hard。
1. Sun-breeding, winning at the starting line. Fifteen days before the seeding, the seeding was rotated every few days under warm scattering light. It's best to see a short, strong, deep green bud (about 1 cm). It's called a sprouts. It's fast and full。
2. Rich earth, a comfortable home for potatoes. Potatoes are “underground fruits” and like dark, cool and loose environments. Cultivation takes place at the height of the plant, during which the soil is grown in stages, and ultimately not less than 20 cm thick. This will prevent the luminous greening of chips (producing toxic ronino) and increase the space for potatoes。
3. Circumculation of flowers and the concentration of nutrition in order to achieve significant results. Seeing potatoes bloom, many people find it nice. But in fact, flower seed consumes a lot of nutrients. In the early stages of the present rheumatism, the removal of the bud from hand to hand, which allows for a more concentrated flow of nutrients to the underworld, is a small and unaffordable trick to achieve high productivity。
In short, growing potatoes is a matter of conversation. And when the best of the land is, it is a resonance of harmony between the three men of the heavens and the earth. And don't go back on a fixed date, learn to observe your land, understand the demand of crops, and you can grow better potatoes than anyone else。
