Intercropping and increasing yield of summer corn

Interlaced corn in summer sowing is a simple method of pollinating female tassels using the pollen of adjoining rows or surrounding tassels. Efforts to increase production. Generally, it can increase grain output by 30-50 kilograms. Why can corn intercalation increase yield? There are three main reasons:

1. Reduce nutrient consumption and early flowering Mature corn is a cross-pollination crop. By pollination, 95% of its pollination rate comes from different plants. In other words, the corn ear can be fully fertilized without relying on the pollen of the tassel. After the detasseling of corn, the nutrient concentrates to supply the ear, which can promote the development of the ear, advance the filaments 2-3 days in advance, and increase the pollination time of the female silk. That is to achieve early flowering, early pollination, early maturation, increased grain weight gain.

2. Ventilation and light transmission, improving the utilization of light energy After detasseling, the tassels on the leaves are reduced, the coverage of the leaves by a large amount of pollen is reduced, and the light transmission conditions of the upper leaves of the ear are greatly improved; Reduce plant height 30-40 cm, Tian asked to form a number of air ducts, improved the ventilation conditions of the upper leaves. Therefore, the light energy application rate is increased, the photosynthesis function is enhanced, more photosynthetic products can be produced, grain filling can be provided, empty stalks, baldness can be reduced, the grain weight can be increased, and the yield can be increased.

3, to reduce various pests, beneficial to increase production and practice has proved that when emasculation of corn, a positive coincidence occurs when corn borers and panicles overlap. Because corn borers are more harmful to the younger leaves, when people are emasculating, they observe that the tassels of the borers and tadpoles must be pulled out. This will have the effect of both emasculation and pest control, which will increase production and income.

In the actual operation, you should also pay attention to the following 3 points:

First, emasculation should be carried out in a timely manner: Corn emasculation must be carried out by grasping Tassel just 1/3 of the time, that is, it can be grasped by hand or peeled off by hand when exposing two tassels to reveal tassels. Drop it. It's not good to be too early or too late. Can not pull tassels too early, but also leaves, too late as loose powder has been lost. At the same time, since the timing of corn tassels extraction is not uniform, generally the first tassels are drawn, which are 2-3 days apart, and it is advisable to pump 3-4 times. For example, individual weak plants can be split by the flag leaves. Pull out. Also pay attention to the selection of sunny days, generally 9 am - 4 pm is appropriate to facilitate the rapid healing of wounds.

Secondly, the detamas should be considered as land plots and varieties should be flexible: hilly lands, low-lying lands, sparsely planted lands, and small or large species should go or not. At the same time, we should also remove the weaker and weaker strains, keep more robust strains, and do not go to the top of the ground. In the middle, there will be more or less scattered land. The dense varieties and high-yield plots are often gone.

Third, the proportion of detassels should be appropriate: Maize pollen has a large amount of pollen, and each tassel can produce 2000-3000 million pollen, and each tassel can meet at least 3-5 female pollination requirements. More than 1,000 effective pollen grains are sufficient for a single ear. Therefore, you do not have to worry about difficulties in pollination after detasseling. Because corn silk can be pollinated in any part of the female leaves. The pollination ability can be maintained for 10-15 days, that is, the filaments remain in a bright state until they are not pollinated, and once pollination stops, they begin to wilt. Therefore, the proportion of detaches is generally no more than half. If it can not be found even when it is cloudy and long-term drought or high-temperature static wind days, it can go up to 1/3. In case of normal weather and high-yielding and dense varieties, 2/3 can be eliminated.

Green Peas, According to the color of their cotyledons, Peas are divided into two types: green skin, green peas, and green skin yellow peas. Green peas are green-green peas. Peas in northeast China are the most famous. It is one of China's important food crops. It has a history of 5,000 years of cultivation. Our company can provide two different frozen peas to meet the needs of different people.
The effect and effect of green peas
Daily green peas can provide catechins and epicatechins as two kinds of flavonoid antioxidants. When people get older, there will be more and more free radicals in the body. Free radicals and aging are positively related. Nutrition in green beans can resist. Free radical-induced diseases, delaying the speed of body aging, as well as anti-inflammatory, spectral antibacterial effects.
Kidneys of green peas
[Appropriate population] Green peas are suitable for menopausal women, diabetes and cardiovascular patients, and mental workers and dieters are also very suitable for eating green Peas. These people can eat green beans to improve disease and physical condition.
[Contrained people] People with severe liver disease, peptic ulcer, arteriosclerosis, kidney disease, gout, low iodine and other diseases are not to eat green peas, so as not to aggravate the condition.
