Sweet potatoes in the end do not have to turn?

One, strictly forbidden

Turning vines will damage stems and leaves, affect photosynthesis, reduce the accumulation of nutrients, so that the weight gain of the potato block is affected, the general reduction of 20% to 25%, the high of more than 30%. Therefore, sweet potato should not turn over during the whole growth period. For the sweet potato field with prosperous growth, it is advisable to use vine tip or light vine to control the growth and inhibit the formation of fiber roots so as to avoid the consumption of fiber roots for nutrients, increase the photosynthetic capacity of the leaves, and promote the expansion of tubers.

Second, cracking fertilizer

Sweet potato root swelling usually begins in late August, and cracks occur between rows due to swelling of roots. At this time, cracking fertilizer must be applied to prevent premature aging of stems and leaves and to accelerate tuber enlargement. The main application of nitrogen and potassium fertilizer, generally in late August with 3% to 5% of potassium sulfate or 15% to 20% of the ash leaching liquid, can also be used 1% potassium dihydrogen phosphate fertilizer, 100 ~ per acre fertilizer solution 150 kg; or per acre topdressing ammonium sulfate 4 ~ 5 kg, watered 500 kg; can also be used for human excrement 200 ~ 250 kg, watering 600 ~ 750 kg, Shun ridge irrigation applied. You can also apply 150-200 kg of gray water per acre. 2% nitrogen, phosphorus and potassium mixture can be applied to lands with premature aging and premature aging.

Third, foliar spray fertilizer

In the late stage of sweet potato growth, the ability of sucking roots in the roots is weakened, and the use of foliar spray fertilizer can ensure the nutrients needed for root swelling. In general, hilly slopes or fields with premature decay should be sprayed with 0.5% urea; leafy vines with prosperous fields should be sprayed with 0.2% potassium sulfate or 5% ash leaching; general fields can be sprayed. 0.4% to 0.5% of urea and potassium dihydrogen phosphate mixture. Each spray fertilizer fertilizer 75 to 100 kg. Spraying time is generally from the middle of August, every 7 to 10 days, 1 spray, spray a total of 2 to 3 times, spray fertilizer time should be held in the evening before the evening, spray should be spray after spraying.

Red light therapy benefits and what is red light therapy?

The function of a red light therapy bed machine is to emit low-level red and near-infrared light wavelengths onto the body. This therapy is believed to stimulate the production of collagen, increase blood circulation, and promote healing in the skin and other tissues. It is used for various purposes, including reducing wrinkles and fine lines, improving skin tone and texture, reducing joint pain and inflammation, and promoting overall well-being.


A safe, all natural process that encourages your body to naturally produce enzymes, elastin fibers and collagen that support the skin`s structure. Thus producing younger, smoother and firmer feeling skin. Here are some common questions that our members often ask about Red Light Therapy:



FAQ of red light bed machine


Q:What should I do before use the bed?
A:Before you begin: Thoroughly cleanse your skin with a gentle, non-drying cleanser. Remove any mineral-based sunscreen, as well as makeup containing zinc or other mineral-based sunscreens. In general, sunscreen won't block red/NIR wavelengths. However, zinc oxide reflects light, which means there's a chance that fewer therapeutic light photons will be available to absorb into the skin. Alternatively, administer the therapy first thing in the morning, before applying any skincare products.


Q: What is red light therapy used for?
A:Red light therapy is used to treat injuries, reduce pain, relax muscles/joints, and increase blood circulation. It is typically used by doctors, physical therapists, and pain clinics as a highly effective non-invasive treatment with no known side effects. It also used by professional athletes to improve performance and reduce the incidence of injuries.


Q:How often can you use red light therapy?
A:You can use red light therapy every day. Most people don't see much benefit using it more than once per day. For handheld treatments your practioner will advise you as to your treatment plan.


Q:How does light energy work?

A: Specific wavelengths of light energy, when properly absorbed, up-regulates compromised cells. The light (photons) energy is absorbed by photoacceptors in the mitochondria and used to create adenosine triphosphate (ATP). The ATP produced then stimulates various metabolic processes which can result in the repair and regeneration of cell and tissue components.


Q: Can this hurt my eyes?

A:The typical human eye responds to wavelengths 400nm to 700nm. The light coming from this device is either visible red or invisible infrared.
