At present, a problem that cannot be ignored in turfgrass construction is re-cultivation. In particular, weeds are becoming more and more serious and make the lawn look different. The harm caused by lawn weeds to the lawn is not only to contend with the lawn, compete for fertilizer, compete for space, and dilute the role of the lawn, reducing the aesthetic value of the lawn. Damaged turfgrass plants are characterized by a slender, fragile, cold-tolerant, drought-tolerant, and trampling-resistant nature, making lawns susceptible to degradation and death, and even causing grass shortages. Therefore, controlling weeds in turfgrass is the key. Weeds that harm the turf are nothing more than the following three categories: one is grass weeds, the other is sedge weeds, and the third is broad-leaved weeds. In these types of weeds, grass weeds and Cyperaceae weeds are collectively referred to as monocotyledonous weeds; broadleaf weeds are also known as dicotyledonous weeds. The herbicides that can be selected for annual grass weeds include valerate, sulphate, chlorate, and disperse phosphorus, and can be used to stabilize and kill grass. The herbicide must be used before germination of the seed. The biological and anatomical characteristics of perennial grass weeds and turfgrass plants are similar. Therefore, a herbicide that kills grass weeds often kills turfgrass. Perennial grass weeds usually use non-selective herbicides such as glyphosate, thatch, chlorsulfuron, and valerian, and can be controlled by spraying or directed spraying. Broad-leaf weed control is mainly controlled by stem and leaf treatment agents, such as paraquat, dimethyl tetrachlorine and dicamba. They are mainly used on mature turf in spring and autumn. Herbicides should be used when the soil is moist and windless. Selective herbicides are generally used after emergence of weeds, and are often used in combinations of two to three species, but not separately. The selection of suitable herbicides and the correct use of these herbicides are key to controlling these weeds. For example, the key to control of annual grasses weeds is controlled before sprouting. There are few types of herbicides that are controlled after emergence, and special care must be taken when spraying to prevent phytotoxicity to turfgrasses. Perennial grass weeds are dominated by vegetative propagation, and it is difficult to control them. During the vigorous growth of weeds during the summer, spot spraying or smearing of high-concentration inactivated herbicides with strong inner conductivity, such as glyphosate, is effective. . The spot application is suitable for controlling weeds whose spores are not higher than turfgrass, and smearing is effective for controlling weeds with higher turfgrass levels than plants grown in plants. For the annual Cyperaceae weeds, it is preferable to use a bud treatment agent such as Shapiron. Application period: After sowing turf is in the period of 4 leaves to 5 leaves, planting turf should be established within 7 days; Chengping turf is before turf returning to green stage. The pre-emergence treatment of broad-leaf weeds is generally combined with the control of grass weeds at the same time, such as spraying scattered phosphorus, acetochlor, etc.; post-emergence treatment should be sprayed in the 2-leaf to 4-leaf period, herbicides, dimethyl tetrachloromethane, etc. Agent. In the control of lawn weeds, the live-planted lawn should be treated with glyphosate and Gramoxone herbicides prior to sowing for turfgrass soil treatment, but care must be taken to maintain the safety for 3 days to 5 days. After sowing, the seedlings are sown. The newly-planted lawns are laid, and weeding methods can be used for soil treatment and stem-leaf treatment. After application, a closed layer is formed in the soil to kill the weeds in the soil. Herbicide resistance is different at different growth stages of the lawn. Herbicides can be used on vegetative propagation lawns, before planting or from planting to planting and turfgrass growth. Live turf, if used for long-term residual herbicide before sowing, will affect the turfgrass seedling emergence rate. From the time of sowing to the four-leaf period, lawns should be selected with high safety herbicides; after the five-leaf period, there are many types of herbicides available.
Black Goji berries is a new treasured food that discovered in recent years,the nutrition value is much more than Red Goji berries, such as mineral elements and trace elements. Black
Goji berry can preserve one's health, it contain a lot of anthocyanins, has the function of
scavenge for free radicals and anti-oxidation which can help to prevent cancer, it also help skin care,
protect eyesight and adjust immunity, improve blood circulation etc.
The procyanidins content of Black Goji Berries
is much higher than blueberries(Black goji berry contain procyanidins is 3690
mg / 100 g; blueberries contain procyanidins is 330-3380 mg / 100 g). This is
the highest ever discovered procyanidins content of natural wild fruit, which
is the most effective natural antioxidant, its efficacy is 50 times of VC and
20 times of VE, the vitamins, minerals and other nutrients content is also
higher, medicinal and health care value is much higher than ordinary red Goji
berry, known as "soft gold".
Black goji
berry typical usage:
1. Direct eating-the fruit may be eaten fresh,
