How to grow sweet corn for thinness and density, how to grow sweet corn

The following principles should be grasped in determining the planting density of corn seeds: 1. Due to the density of varieties: late-maturing varieties have a long growth period, tall plants, and high productivity per plant, so they should be suitable for thinner; Early maturing varieties should be suitable for taller.

Flattened leaf-shaped varieties, easy shade between leaves, should be appropriately thin: vertical leaf varieties, good light transmittance, should be denser. 2. Determine the density under fertilizer and water conditions

The water and fertile land should be dense, and the dry and thin land should be thin. 3. Determine the density according to climatic conditions: for the same type of variety, the suitable density in the south should be higher than that in the north

The planting density should be higher at higher altitudes in the same area than at lower altitudes; The growth period of summer-sown maize is shorter, and the density should be higher than that of spring-sown maize. In addition, in low- and medium-yield fields with poor fertility, less fertilization and sparse density, equal row spacing planting can generally be used to make full use of light energy and soil fertility. In high-yield fields with good water and fertilizer conditions, more fertilization and high density, it is generally advisable to use wide and narrow rows to effectively solve the problem of ventilation and light transmission in the middle and late stages.

1. Sowing seedlings is the basic requirement of sweet corn planting methods, first of all, we must select seeds with high germination rate with suitable sweetness and soft texture, and ensure that the size of the ears is the same, strong disease resistance, and then put it in warm water to clean it, and generally choose the best planting in March in spring, which is also a period with a higher survival rate.

2. If you choose the soil with general fertility, it is best to add an appropriate amount of phosphorus and potassium fertilizer solution to stir it fully, and the soil will be deeply cultivated once before cultivation to remove the weeds growing around, and keep the soil loose and flat The best way to keep it moist after watering it once.

3. The general planting of sweet corn should be isolated from ordinary corn, so as not to affect the yield of sweet corn, the spacing between ordinary corn and sweet corn should be kept around, and the thickness of the covering soil should be kept to about 5 cm after planting, and a thin rotten organic fertilizer can be applied at the bottom of the hole.

4. When planting in the seedling stage of seeds, it is best to keep the soil moist frequently, and do a good job in the prevention of pests and diseases during the growth period, spray an appropriate amount of chlorothalonil solution on the soil from time to time, in addition to frequent weeding treatment, and increase the amount of watering appropriately in the middle term, so as to maintain the normal growth of the root system.

5. When there is a larger ear growing on the main stem, it is necessary to cut off the other stems, and try not to hurt the main stem when pruning, so as to avoid affecting the normal growth of the plant.

Hello, the planting of sweet waxy corn needs to pay attention to the following aspects:1Soil selection:

Sweet waxy corn prefers fertile, loose, well-drained soil. Before planting, soil improvement should be carried out, and organic fertilizers should be added to improve soil fertility. 2.

3.Sowing method: The seeds of sweet waxy corn are larger, and they are carried out in the form of live broadcast or hole sowing like a slow bucket.

During the live broadcast, the seeds are evenly sprinkled in the ditch, and the seeds are put into each hole during hole sowing, and 2-3 seeds are placed in each hole. 4.Management Measures:

Sweet waxy corn needs to be watered appropriately during the growing season to keep the soil moist. At the same time, it is necessary to weed, loosen the soil, and fertilize in time to maintain ventilation and light transmission to prevent the occurrence of pests and diseases. 5.

Harvest time: Sweet waxy corn can generally be harvested in about 90-100 days during the growth period. Be careful not to damage the corn kernels during harvesting, so as not to affect the quality.

In short, planting sweet waxy corn needs to pay attention to soil selection, sowing time, sowing methods, management measures and harvest time, etc., only by doing the above points well, can you get high-quality sweet waxy corn <>

In the process of planting sweet corn, first of all, we should select seeds with high germination rate with suitable sweetness and tender texture, clean them and cultivate them in March in spring, add an appropriate amount of phosphorus and potassium fertilizer to the soil and stir them fully, and plant them in isolation from ordinary corn after planting, and keep the thickness of the covering soil about 5 cm.

Sowing seedlings is the basic requirement of sweet corn planting methods, first of all, we must select seeds with high germination rate of suitable sweetness and soft texture, and ensure that the size of the ear is the same, strong disease resistance, and then put it in warm water to clean it, generally choose the best planting in March in spring, and this is also the period of higher survival rate.

If you choose the soil with general fertility, it is best to add an appropriate amount of phosphorus and potassium fertilizer solution to stir it thoroughly, and carry out deep ploughing treatment of the soil once before cultivation, remove the weeds growing around, and keep the soil in a loose and flat state.

The general planting of sweet corn should be isolated from ordinary corn, so as not to affect the yield of sweet corn, the distance between ordinary corn and sweet corn should be kept around, and the thickness of the covering soil should be kept to about 5 cm after planting, and a thin rotten organic fertilizer can be applied at the bottom of the hole.

When planted in the seedling stage of seeds, it is best to keep the soil moist frequently, and do a good job in the prevention of pests and diseases during the growth period, you can spray an appropriate amount of chlorothalonil solution to the soil from time to time, in addition to frequent weeding treatment, and increase the amount of watering appropriately in the middle term, so as to maintain the normal growth of the root system.

When there is a larger ear growing on the main stem, it is necessary to cut off the other stems, and try not to hurt the main stem when pruning, so as to avoid affecting the normal growth of the plant.
