Why do you want corn seedlings to be planted side by side? That is because corn cannot be sown normally in mountainous regions. Maize seedlings are a type of corn seedling transplanted on the side edge of a plastic film in corn cultivation in mountain areas. A new cultivation method has the following advantages compared to transplanting corn seedlings in the inner membrane.
Maize transplant seedlings
First, it can further enhance the lodging resistance of corn
The maize seedlings were transplanted in the film. Although the lodging resistance was enhanced compared with the field live film coating cultivation, due to the loose soil in the film and most of the buried fertilizers were shallow, the root system of the corn was affected by the fertilizer and water movement in the soil. The surface layer is therefore still relatively easy to fall. Maize seedlings are planted on the membrane side. Although most of the roots are attracted to the membrane by the water and fertilizers in the membrane, some roots are still born out of the soil with a solid film. The effects of transplanting seedlings are more obvious, and the plant height and ear position are significant. Lowering, later soil management, thus greatly enhancing the ability of corn lodging, the risk of inverted significantly reduced.
Second, can increase the temperature of the film moisturizing, weeding function
In the side planting of corn seedlings, the film surface is kept clean and intact as compared with the film planted in the film, so it is more advantageous to increase the temperature and moisture in the film soil. Although the seedlings are transplanted on the membrane side, most of the root membranes extend within the membrane, so they can also function as root-enhancing seedlings, and because the membrane is tightly closed, the soil surface temperature within the membrane is significantly increased and it can be more effectively killed and burned. Weeds. As long as the ridge is flat, it can basically control the damage of weeds. If a chemical herbicide is sprayed on the ridge surface of the cover film, stable and good weeding effect can be achieved.
Third, it will facilitate the storage of water, facilitate transplanting, improve the survival rate of transplanting and drought resistance in the later period.
After the dry land is covered with membranes, the soil moisture in the membrane is affected by the thermal movement and evaporates to the surface of the mulching film. In the case of low temperature, the water condenses into water droplets and finally slides to both sides of the mulch. Rainfall also rains on both sides of the mulch during rainfall. Therefore, after the film is covered for a period of time, the edge of the film is best and the replenishment is the easiest. If corn is transplanted on the side of the membrane, it is easy to grasp the seedlings in a timely manner and the transplanting operation is convenient. The drought resistance at the later stage is also strong. Transplanting in the film, if the film is subjected to continuous high temperature and drought, the loss will be faster, which may lead to the lack of soil in the middle of the film, which is not only inconvenient to plant, but also difficult to make up the water, thus affecting the survival rate of transplanting. If the drought is later, it will not be easy to store water in case of a small amount of rain.
Fourth, to facilitate a dual-purpose membrane, improve the efficiency of the use of film
Corn transplanted in the film, although the old film can also be used directly to hole seeding, but the insulation effect is poor. Maize transplanted on the membrane side, without destroying the ridge, basically remained intact. In autumn and winter, if the membrane surface is punched and planted for other crops, the effect of heat preservation and soil conservation is better, and the loss of fertilizer in the membrane is small, and there is less corn residue in the soil. It is conducive to the growth of crops and thus plays the role of "advancement of secondary mulch film and harvest of two crops."
V. It can increase corn density and fertilizer input, increase corn production
Corn transplanted in the film, the density is too high, fertilizer and water is too easy to cause lodging. Transplanting maize on the membrane side significantly increases the lodging resistance, so the transplanting density can be appropriately increased and the fertilizer input can be increased, thereby achieving the goal of increasing the yield per unit of corn. Maize collaterals should be technically noted:
1, appropriate early nursery, with enough basic seedlings. Two-layer mulching technology should be adopted to cover the seedlings, so that the sowing date of corn can be advanced by 5-7 days, so as to make up for the lack of accumulation of corn on the membrane side. The number of maize seedlings should be increased by 500 on the original basis of 667 m2;
2, full base fertilizer, increase the amount of fertilizer. As corn is planted on the membrane side, the membrane surface is complete, and the fertilizer in the ridge is closed better, and the fertilizer is volatilized and lost less. In addition, factors such as increasing the density of corn and the need for large amounts of fertilizers for “one membrane and two uses†have to be increased. Base fertilizer 667 m2 farm fertilizer should be more than 5000 kg, fertilizer 667 m2 with compound fertilizer, ammonium bicarbonate each more than 50 kg, to ensure that a full base fertilizer, taking into account the high yield of double crops.
3, early ditch buried fertilizer, foot ridge mulching film. On the basis of deep-digging reserved rows before the beginning of the year, early spring ditching and ridges are required. The ridges should be ridden in time. The ridges should be as flat as possible, and then the membranes should be tightly covered. If possible, the ridges can be sprayed before the film is covered. Herbicides to eliminate weed hazards;
4, the size of seedlings, improve the transplant density. When planting must be done size seedlings classification work, to prevent the size of the seedlings mixed with high density under uneven growth, more empty stalks and other issues. The transplanting density can be increased by 300-500 plants per 667 m2 in the membrane.
5, combined with topdressing, soil protection. Pay attention to properly increase the amount of panicle fertilizer to recover the earthworm and prevent it from falling due to high density. Tasting male corn foliar, can also play a significant anti-fall effect.
