Summer corn is affected by ecological factors in the planting process, as well as human factors. Like temperature, solar radiation and moisture are all climatic factors. In order to be able to increase its output, it is very important to adopt a reasonable cultivation and management method. Row spacing has already carried out some researches on the yield, but there has been no report on the effect of microclimate on maize yield under different row spacing conditions of the same variety. The monitoring of the microclimate can be carried out using a hand-held meteorological station. The instrument can accurately monitor the climate change and provide the basis for the relevant measures.
The grain filling stage after corn silking, that is, two years from August 17 to September 10, was observed for 50 days, and the first ear position was highest at 8:00, 14:00, and 20:00 in each day. Perform fixed observations of the microclimate in the field. Four processes are performed at the same time. The temperature, humidity, and wind speed were measured using a hand-held meteorological station NK4000; the amount of effective light was measured using a photo quantum meter (3415F).
Corn is a high-light-efficient C4 plant. More than 90% of the dry matter in corn comes from photosynthesis, and whether corn can maximize its potential for high-yield production is closely related to population structure allocation and population light energy utilization. Studies have shown that row spacing arrangement has a certain influence on the growth and yield of corn. Different arrangement of row spacing influences the structure of the population, resulting in the change of the microclimate in the field, which affects the yield and product traits of maize. By changing the arrangement of row spacing, the conflict between field microclimatic factors is coordinated to achieve the most suitable ecological environment for the group.
The hand-held meteorological station can observe the influence of different row spacing on the microclimate and yield in the field under the direction of planting rows and rows of planting densities of 67,500 plants/hm2. It can be seen that the planting direction is the east-west direction and planting density. At 67,500 plants/hm2, the row spacing is 50 centimeters. The light, temperature, water, and gas in the group are fully utilized. At the same time, the relationship between individuals and groups is better coordinated so that the group's high yield potential is better. The play. This study only focused on the east-west direction of planting, and the planting density was 67,500 plants/hm2. The best row spacing was 50 cm. The effect of planting direction and planting density on corn yield and microclimate in the field in the future Will do further research.

Retort technology means food is pre-cooked, needing little (if any) additional preparation. And for those consumers that appreciate convenience, the less cooking, the better! Today`s consumers demand convenience, so the flexible retort pouch is appealing because it can be re-sealed. Someone who opens a can of tuna and prepares half of it must then find a way to store what remains. With a re-sealable zip seal pouch, there`s no need for other storage methods. Believe it or not, retort technology makes food taste better. Here, food is spread out evenly, so it cooks faster than in a can. In cans, product at the edges can overcook, while product in the center can undercook. This problem is eliminated by the flexible pouch.
Flexible retort pouches are longer and wider than cans, so space for your brand message is increased. You can use graphic designs to catch consumers` attention. The pouches` unique construction (using high-grade plastic, aluminum, or a blend of the two) take well to high-tech printing methods – so your artwork will really stand out at retail. Retort flexible pouches can be made to stand up on retail shelves, or hang in a peg display, which increases your merchandising opportunities.
What is one of the biggest complaints consumers have about cans? Sharp edges, of course! With retort flexible pouches, this problem is completely eliminated. Before packages are filled, they can be stored flat, unlike cans. With warehouse space usually at a premium, this can free up a lot of room, and make for very happy warehouse managers. Retort packages weigh less than cans, so you`ll save money on transportation and shipping.
Most people think cans are more durable. Actually, retort flexible pouches are because they are made of several different high-quality layers that offer superior strength and resiliency. No dents here. In closing, retort pouches continue to gain popularity along with other styles of Flexible Packaging such as standup pouches and barrier bags. While using cans may be a thing of the past, retort pouches and other types of flexible packaging are certain to be in our future.
Traditionally used for coffee and tea, this side-gusseted bag is now growing in popularity in the food, snack and baked good industries. Its side-gusset feature allows your package to be displayed vertically or horizontally, giving retailers more options for shelf display.
