The greatest difficulty in planting rice in cold areas such as heilong river, inner mongolia and north hebei is that short, long-term, effective temperatures are not sufficient。Cold ricePlantation techniquesAfter all, it's the two core issues of what kind and when. I planted rice for more than 20 years in the p-5, and from the first year i lost money until i stabilized in the acre for about 1,300 years, enough to write a book. Here's a reference for friends who grow rice in cold areas。
How to grow cold rice
The selection of seeds is a top priority for cold-water rice cultivation and is more important than irrigation than fertilization. There's only 120 to 135 days of land in the long term, and you have to pick up early ripen varieties, like dragons 31, dragons 45 and five rice 45, which are more insured within 125 days of maturity. Don't get caught up in "high-yielding acre" in an instruction book♪ a season of the blind ♪I don't know. My neighbour planted a medium- and late-cooked variety last year, and only at the end of october managed to catch up with a frost, and the whole field was green, which cost more each year than the earlier。
There is also a point that can easily be ignored: the resilience of varieties and their underlying manifestations. In the cold, it is clear that the temperature may be just a dozen degrees when seedlings are laid down, the variety is weak and slow, and the whole life is on schedule and, finally, the number of effective ears is not going to fit. The selection of varieties to look at literature data and to ask local agricultural stations or cooperatives about actual field performance is much more reliable than reading papers。
A few months of cold rice cultivation
Plug-in time looks simple, actually. Most old farmers think "the sooner, the better." one more day's heat. But in the cold, rice is growingAge control is more critical than pluggingI don't know. The temperature of the seedbed is not keeping pace, the seedlings are ill, the roots are underdeveloped, and the length of the implants slows down, thus delaying the period of gold that really needs to be divided. I usually wait in the middle of may to stabilize the temperature at more than 12 degrees and move the plugs, rather than "strength."。
It's also a big pit. In the cold, the water is cold, too shallow, and the wind blows back and forth, and the deep twilight is crushed and the effective fraction is low. The way i found it was to control the depth of the interpolator's land cover at 2 to 3 centimetresDon't pour deep water within three days of the plugLet the seedlings get in the mud as soon as possible. The water is too deep to slow down the roots and grow for a week. It's a lot of new people who don't understand, two or three pounds less in an acre and a hundred pounds less in a season。
Rice is grown in the cold, and every ring is stuck in the air, and the results are different for three or five days. The technology thing, the book says it's an ideal state, and the real answer lies in the ground. And when you're down on the ground, you're looking at the water, you're looking at the sky, you're planting every season, and the production comes up。
