The following small series organizes the misunderstandings that we can easily enter during the process of corn topdressing and watering(seed starter trays), and correct them in time to achieve the effect of increasing income and increasing yield. Using high-quality agricultural fertilizer as base fertilizer can increase soil organic matter and soil aggregate structure(wholesale greenhouse pots), and provide various nutrients needed for corn growth and development.

In the seedling stage before jointing(propagation tray), if the topdressing and watering are not carried out according to the actual conditions such as the degree of drought, good moisture, and the strength of the seedlings, the seedlings in the upper part are often long, and the roots in the lower part are difficult to deepen, so that the seedlings are lost(greenhouse supplies pots). The opportunity for the seedlings to exercise, to plant the plant after lodging to bury hidden dangers.
Fertilizer and water are prerequisites for high yields of corn(plug trays). The vegetative growth and the reproductive growth go hand in hand, and the booting to the heading reaches the peak period, and the flowering to the filling stage turns to the reproductive growth. The cultivation should be carried out with “three top dressing, three watering, and three medium tillage”(plastic grow pots). After the beginning of jointing, the first point of topdressing is carried out, and timely tillage is carried out.
But not blindly topdressing and watering, not only can not achieve the high-yield effect, but also wasted fertilizer and manpower, not worth the candle(gallon plant pot). Excessive topdressing and watering during the filling period not only increases investment, but also wastes fertilizer, and also causes corn to be late and ripe, and suffers from the adverse consequences of frost(flat plastic tray). The period from the booting to the filling stage is the period in which the water and fertilizer are most needed.
After the start of the booting, the second top dressing is carried out, and the third point top dressing is carried out during the grouting(cell trays). The total amount of the three top dressings is preferably not more than 30 kg. The amount of topdressing can be grasped before the light, medium and heavy weight: the jointing period is 30% of the total fertilization(seed propagation trays), the booting stage is 60% of the total fertilization, and the filling period is 10% of the total fertilization.
Otherwise, the spring sowing corn starts from the jointing stage, and we will share with you how to use tea to cultivate green radish(gallon nursery pots). Some experiments have shown that: the application of zinc fertilizer in corn, the number of grains per ear can be increased by 50 to 80, the weight of 1000 grains can be increased by 15 to 30 grams(18 cell seed starting trays), the rate of baldness is reduced by about 50%, and the yield per mu is increased by 8% to 15%. Fertilizer does not have this advantage.
It is urgent to consider some quick-acting nitrogen and phosphorus fertilizers to prevent premature aging and cultivating(black plastic plant pots). Promote grouting and grain fullness and increase 1000-grain weight. This time, "seeding the seed fertilizer" should be applied early, the hole is applied, and the amount is applied(20 cell seed starting trays). It is necessary to change the old practice of "establishing autumn hooks, eliminating leisure and other autumn harvests", to be shallow, diligent, and always keep alive.
The effect of top dressing has been exhausted, and the nutrients in the soil have not met the growth needs of corn(square nursery pots). Micro-fertilizer has a great influence on the growth and development of crops. In terms of zinc fertilizer, corn is very sensitive to its response. "Insufficient base fertilizer to chase (chemical) fat generation" can only make the land more and more thin and thinner(40 cell seed starting trays). But improper use is just harmful and unprofitable.
