Wheat set peanuts are planted in the wheat rows before wheat harvest, in order to extend the growth period of peanuts, make up for the lack of caloric resources, and realize the double ripening of wheat and peanuts a year. system. In recent years, affected by the adjustment of corn price and planting structure, the area where summer corn was originally grown has also begun to develop summer peanuts. Wheat set peanuts have a symbiotic period of wheat and peanuts, and have high requirements for peanut planting technology, especially the sowing process. If they are not done well, it is difficult to achieve complete seedlings, complete seedlings, and strong seedlings, which has a great impact on peanut production. Right now, when it's time to sow peanuts in wheat sets, we must do the following three things. 1. Seeding in time to strive for strong seedlings Peanuts and wheat have a symbiotic period of about 10 days. If peanuts are planted too early and the symbiosis period is long, peanuts are prone to form tall seedlings, affecting growth and development and flower bud differentiation, even if the management is strengthened after the wheat is harvested, it is difficult to make up; if interplanting is too late, it affects the entire development of peanuts and cannot achieve extended growth. The purpose of the period is not to meet the requirements of peanuts for accumulated temperature to the greatest extent, resulting in the pods in the later stage not being full and full, the kernel yield is reduced, and the degree of damage to peanut seedlings during wheat harvest is also increased, resulting in reduced production. The interplanting period of peanut mainly depends on the wheat planting method, population size and degree of canopy closure in the field. Normally, interplanting peanuts in wheat fields should be sown 15 to 20 days before the wheat harvest. Medium-high-yield wheat fields are heavily shaded. The interplanting period should be appropriately moved back. Low-yield wheat fields and wide and narrow rows of wheat fields can be properly interplanted in advance. In the central and southern part of our province, the best sowing period of wheat and peanut is generally from May 20 to the end of May. The southern part should be early and the northern part should be late. 2. Reasonable close planting, strive for the whole seedling The reasonable planting density of Maitao peanut is generally 10000～11000 holes/mu, and 2 seeds are planted per hole. The hole spacing of peanut ridges is mainly determined by the way of wheat planting, with the principle of ensuring density. For peanuts with large ridge distances, it is necessary to appropriately reduce the pit distance. For peanuts with small ridge distances, it is possible to increase the pit distance appropriately. Note that the ridge distance is greater than the pit distance. It is not recommended to plant plants with the same ridge and hole distance. In order to ensure a reasonable planting density, the seeds must be carefully selected before sowing. After peeling the peanuts, the grains, diseased grains, and bad grains are removed, and the seeds with large and full grains, bright skin, no disease spots, and no damage are selected as seeds, and Sowing seeds after grading. In order to prevent root rot, stem rot and the occurrence of underground pests, the lack of seedlings and ridges affects the planting density, and seed dressing should be carried out before sowing. When sowing, it is necessary to ensure the quality of sowing, so that the depth of sowing is consistent, the cover is tight, and strive to sow the entire seedling. 3. Suitable sowing and seeding, striving for Qi Miao When intercropping peanuts in wheat fields, soil moisture must also be considered. Normally, peanuts should be moistened before sowing and suitable for sowing. Generally, it should be 7 to 10 days before peanut interplanting, combined with pouring wheat grouting water to create moisture. However, it is best to build soil and then sow clay soil and loam. Sandy land and sandy soil can be planted before sowing, and can also be planted before watering. Sowing seeds is the key to achieving the completeness of Miao Qi Miao.

Fiberglass Mesh
Fiberglass mesh is made by soaking and coating with macromolecular alkali-resistant latex on the basis of C-fiberglass and E-fiberglass. The color of fiberglass mesh is white, black, organge, blue, yellow or as per customer's needs. And the fiberglass mesh's package can also as per customer's requirement to finish. The fiberglass mesh be widely used on : wall reinforcement, reinforced cement products, waterproofing favrics, the roof waterproof, enhance the skeleton of plastic and rubber, fire prevention board, highway parements, joint tapes of buildings.
The advantages of fiberglass mesh:
high strongth
good alkali resistance
prevent cracks and deformations
easy to be constructed
more durable
