What is the difference between close planting and sparse planting of Lagerstroemia indica?

After the summer harvest, summer sowing reached its peak. For the area planted with wheat, the area planted with the next crop of corn is larger.

In the process of planting summer corn, many farmers have such a problem. Is summer corn densely planted or sparsely planted? Which method is more productive under the same plot and management?

From the analysis of the actual planting process, combined with the growth characteristics of corn, if the planting density is too dense, for example, under normal circumstances, 4000-5000 grains are planted per mu, and 8000 grains are planted as a result, resulting in too many corn plants, insufficient water and nutrient supply, and weakened ventilation and light transmission in the field, corn will not only not increase production, but also reduce production.

If the planting is too thin, such as sowing 2000-3000 seeds per mu, although the water supply per plant is sufficient, photosynthesis is not hindered, and the ventilation is good, each corn grows well, but the overall number of plants is small, even if the yield per plant is high, the overall yield will still decrease.

Therefore, if we don't consider the actual situation, planting corn too densely or too thinly will not achieve the purpose of increasing production, on the contrary, it will reduce production.

So if reasonable close planting and reasonable sparse planting are within a reasonable range, small helpers prefer reasonable close planting, and I think reasonable close planting is easier to increase production.

Pay attention to the word "reasonable" here, because there are many factors that determine the planting density of corn, such as variety, soil fertility, management level and so on.

In terms of varieties, there are many varieties of corn on the market, and the characteristics of each variety are more or less different.

In terms of plant height, the varieties with high plant height are sparse. If the planting is too dense, the chance of lodging will increase in the later stage.

On the contrary, if the plant height is relatively low, it can be properly planted in close density, which can effectively increase the yield within a reasonable range.

In addition to plant height, the characteristics of leaves are also different. If it is a relatively compact corn variety, the planting density can be appropriately increased.

On the contrary, if it is a flat-stubble corn variety, it needs to be planted thinly.

As far as soil fertility is concerned, if the soil in our own plot is poor, the planting density can be appropriately increased and the adult rate can be improved under the condition of applying more base fertilizer. If the soil is barren and sparsely planted, the rate of plant formation in the field is even lower.

On the contrary, if the soil fertility is good, it can be planted thinly to increase the weight of corn per plant. If it is planted too closely, it will lead to too many plants in the field and it will be impossible to increase production.

From the management level, from planting to harvesting, the more reasonable the management is, the more suitable the sparse planting is, and the growth quality of a single plant can be improved. Reasonable sparse planting does not mean that the yield will decrease, on the contrary, it is higher than close planting.

Don't ask if corn is planted with herbicide once. It is suggested to plant with reasonable density and increase yield through quantity.

Judging from the actual planting process of summer corn, it is in the high temperature season. If it doesn't rain for a long time, it needs irrigation and watering.

Some farmers are inconvenient, or go out to work after planting corn, so they don't water it. In this case, it is suggested to increase the planting density appropriately.

When the soil is dry for a long time, the emergence rate will decrease. In order to increase the number of effective seedlings in the field, it is a common practice for farmers to increase the amount of sowing.

For example, when sowing corn in Xiaoshoubang village a few days ago, several farmers bought 4,000 corn seeds and put them in a bag, prompting to sow an acre of land, but when sowing, they told the seeder that the machine needed to be adjusted, and this bag only sowed 8 seeds.

After one bag was emptied, the other bag was emptied by about one fifth.

In the high-yield exchange group of small helpers, a group friend from Xinjiang said that the local plants are all close-planted varieties, and 7000-8000 seeds can be sown on an acre of land (one acre of land is equivalent to two acres of land on our side), and the management is more refined. Drip irrigation is used for water, water and fertilizer integration, topdressing keeps up, and pest control has not fallen. The yield of corn in an acre of land can reach about 2000 Jin.

Seeing here, I believe everyone has the answer to the question of whether summer corn is planted densely or sparsely.

As long as the planting density is properly increased within a reasonable range, the yield of maize can be effectively increased.

But how to define "reasonable" needs to be decided according to your own circumstances, and it is very important to adapt to local conditions.

In the opinion of the assistant, if the dosage of 10%-20% is appropriately increased within a reasonable range, the planting density can be effectively improved. If it increases too much, it will exceed the "reasonable" range, or it will not increase the rate of return.

Of course, you can also buy seeds according to the instructions.

What do you think of this? In addition, whether to plant corn thinly or densely? Or according to the dosage on the instructions?
