In recent years, in the cotton field air travel, the cotton field cover technology has been experimentally promoted for many years(plastic flower pots manufacturers). According to the practice summary, this technology has good ecological and economic benefits for cotton production. Before the line was closed, the empty line was exposed for more than two months(20 cell propagation trays wholesale). Due to the large amount of evaporation, the cotton was susceptible to drought.

After the wide line of cotton was covered with grass, the soil moisture content increased significantly(nursery plant trays). Soil nutrients are easily lost. Covering grass in cotton fields can prevent nutrient waste. Covered cotton fields are 2.1% -16.8% more alkaline hydrolyzed nitrogen than uncovered grasses(105 cell propagation trays wholesale). No matter which kind of grass covers the cotton field, after the heavy rain has washed away, the covered grasses can be seen to see that the soil remains loose.(cheap v13 nursery pots manufacturers saudi arabia)
After the cotton fields are covered with grass, the weeds' germination environment is deteriorated and weed growth is suppressed(germination flats). Light and easy to straighten. The temperature in the 5 cm depth of the soil in the covered cotton field is lower than that of the uncovered grass by 1.3 ° -3.8 ° C. It is appropriate to increase the amount of grass for covering fresh grass(24 cell propagation trays wholesale). After covering the grass, the cotton plant lodging is significantly reduced, and the degree of lodging is reduced.
The rapid growth of cotton from May to June is also a period of symbiosis with weeds(gallon planting pots). According to the survey, the covered cotton fields have 121.5-201.6 fewer weeds per square meter than the uncovered cotton fields. Cotton planted in a nutrient bowl for seedling transplantation(162 cell propagation trays wholesale). Because the main root is cut, and the cotton with high peach weight and high boll weight is in the middle and late stages, once it is exposed to storms, the cotton plant lodging rate is high.
According to the measurement, the organic matter content increased by 0.03% -0.30% in specific operations(plug tray nursery). The investigation found that the cotton-covered cotton had a drop of 8.2% -17.4% in the drop rate of buds and bolls compared with the non-covered cotton. Covered cotton fields and grasses can rot in cotton rows in that year(200 cell propagation trays wholesale). Compared with uncovered cotton fields, fertilizer investment per acre can be saved by about 30 yuan.(cheap v13 nursery pots manufacturers saudi arabia)
Covered cotton is more concentrated on peaches than uncovered cotton(21 cell trays bulk), and it is earlier in flocculation and marketed earlier, with an average increase in lint yield of 5% -7% per mu. In order to better exert the effect of covering grass in cotton fields, it is necessary to pay attention to the following: after repeated comparisons in practice, it is advisable to cover 200-250 kilograms of hay per cotton field(288 cell propagation trays wholesale). The soil moisture content of cover grass is 5% -12% higher.
(cheap v13 nursery pots manufacturers saudi arabia)After cultivating the cotton, the grass is directly covered in the wide rows of cotton, and it should be covered evenly(162 cell trays bulk). For ridge cultivation, ridges should be covered with grass(112 cell propagation trays wholesale). In recent years, in the high temperature season, after exposed heavy cotton rains, the cotton bottom fertilizer is applied sufficiently, and the cotton bud period is more vigorous, and the grass can be covered after stubble cultivation or soil cultivation.
For those who do not apply base fertilizer, apply enough manure (leaf fertilizer) to raise the soil and then cover the grass(plant start trays wholesale). The time is preferably from early June to early July. There are many kinds of grasses for cotton field cover grass, such as straw, wheat straw, rapeseed, corn, legume stalk, glume and aquatic grass(128 cell propagation trays wholesale). After the cotton is sealed, the grass can rot after a few rains. The thickness of covering grass is 5 -8 cm.(cheap v13 nursery pots manufacturers saudi arabia)
