The most expensive and easy to waste of corn in the autumn is fertilizer, and many farmers have lost their production of fertilizer in a season, all at the right time and at the right time. Take it from belowKee fatThe operational points of the five steps of this fattening can be used to save money。
The doorway to ki-fat
Autumn corn-based fertilizer accounts for about half of the total, with cutting-edge strips or caves being planted in the soil. At the same time, small seedlings take root with five to seven kilograms of ammonium sulphate or ammonium nitrate as fertilizer. Don't forget the trace elements, two to four grams of zinc sulphate per kilogram of seed, or impregnate with zero-two percentage points of zinc sulphate, which can effectively reduce zinc deficiency。
What is most likely to be neglected is the quality of the ground. The ground is not penetrating, the organic fat is not fully decomposed, the roots can't go down, and there's a trade-off on the back. It is recommended that the application of the fertilizers one or two weeks before the seeding take place, allowing for full exposure of the manure and soil to decomposition, would be much better than on the day of the planting, and the seeding would be solid。
FattyGo after the moisture
The fattening follows the four to five leaves of the seedlings, which combine the seedlings with the grass-planting. The principle is six words: early, light, partial. If the ground is poorly prepared, the base fertilizer is scarce and the base is thin, it has to be filled with a hand; if the ground is strong, it can be saved or halved, rather than forced into the ground, and the weight is bigger and the roots are broken。
The seedling is not to fall under the seedlings and is torn down by about 10 centimetres on either side of the seedlings to guard against burning roots. A few kilograms per acre of nitrogen-efficient fertilizer is sufficient, and the soil is absorbed by the application of rain so that it can melt into the soil. It's worse than not to see a small baby so that it can be burned。
Don't lose your weight
The decomposition is also called decrepit fattening, which is applied at the beginning of the extension of the corn base, at the stage of the spread of about seven to nine leaves, accounting for 20 to 30 per cent of the total amount of fat. The most recommended approach is to apply 1,000 kg of corroded or fertilized fat per acre, with an additional 7 to 10 kg of compound fat, organic inorganic, and a thick and solid strawl in the back。
The core principle of chronology is neutrality. Those who are weak and slow-growing in the field will be left alone to keep the size of the whole plot even and ensure balanced growth throughout the field. It's a time when you're lazy and you're not gonna be able to make it up because the size of the ears is basically fixed。
Re-profiling
It's the most heavy in the season, accounting for 60 percent of the total. The timing is very specific: the male is growing into a quadrilateral, the female is starting to divide, i. E., the loudspeaker, with about 10 days left. This window directly determines the size of the ears and the number of particles, without a second chance and must be seized。
It must be fast-activated nitrogen fertilizer, urea or ammonium nitrate, so that roots are rapidly absorbed within 10 days. And lower the bottoms, and more low. If it is done with water or with rain and without water on the ground, more than 30 per cent of the loss of fertility is equivalent to a waste of money。
It's the end of a diet
Pumps of fertilizer only concern one thing: rooting leaves, preventing post-feat and early decay, and extending the function of the green leaf to increase the particle weight. It's light, only about 10% of the total fat catch. When a leaf is found to be yellow and the lower leaves dry up early, the particle fat is increased as appropriate; the leaves are still green and normal, with little or no pressure。
Pumps of fat are the most taboo. Many farmers feel that they will end up giving another piece of fatty, and in fact the later root system has decreased its absorption function, and the nitrogen has given it too much to eat, causing it to fall back and become too green or dry. With a soft push and a half-month of green leaves, thousands of grains will be visible, much more fat than a dozen pounds。
Don't do that
The ratios and usages described above are common references, with three things actually going down: soil fertility, base weight and sapling. He who is strong in the earth, and is steady in the earth, and he who is strong in the earth, and he who is weak in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, is firm in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the earth, and he who is strong in the wind. Instead of a set of programmes, all the places would have to be adapted flexibly。
The same land is much different from marginal, ground-top and middle-faced seedlings, and it is applied in a sub-region, in a long way and not in a jar. Today, soil formulas are being used more and more widely, and dozens of dollars are being used to measure soil, which is far more reliable than old experience and less expensive and less wasteful。
What are you going to do with the fertilizing this fall? Is the base strong enough to catch up, or is the ground weak enough to catch up? Let's talk about your program. Let's see if it works。
