Extended tuber storage method

Pre-processing method: Use MH. 2 to 3 weeks before potato harvesting, use 100 to 2500PPm of fresh green pigment for foliar spray (the specific time and dose will depend on the variety characteristics and growing trend, the growth rate will be slightly higher and the dose that is not resistant to storage will be slightly higher, otherwise it will be slightly lower). It can inhibit post-harvest germination and prolong storage time. If pre-harvest treatment combined with appropriate low temperature storage is more effective.
In addition, the use of 500 ~ 1000PPm2, 4,5, -7 foliar spraying 1 week before harvest can also extend the storage period of potatoes, with 2,4-D, naphthylacetic acid treatment has a certain effect, but these agents The tubers have side effects, and the quality of the tubers after storage is poor, so they are not widely used. After pre-harvest treatment, the sprouting ability of the shoots on the tubers is weak, and most of them cannot grow into normal plants, so it is not suitable for seeding.
Post-harvest treatment: The use of methylnaphthaleneacetate (MENA) to treat postharvest storage of potatoes to prolong their dormancy and shelf life.
There are two ways:
One is to mix naphthalene acetic acid with fine soil and other fillers, and then pick it up into the two months after harvest. Dosage: 200-500 grams of 10,000 kilograms of potato chips.
The second is to dissolve the methyl naphthaleneacetate after it is dissolved on the paper scraps and mix it with the potato chips. Both treatment methods should be stored in a closed library after treatment to facilitate the action of methyl naphthylacetate on buds and interfere with cell division. However, the treated tubers should be placed in ventilated place for a few days before use to allow the naphthylacetate to evaporate and remove the poison.

Amino Acids

Amino acids are the basic units of proteins and are essential organic compounds in life. There are about 500 different amino acids in nature, but among the amino acids that make up the proteins of living organisms, 20 are standard amino acids, which are connected in different sequences to form proteinaceous proteins that perform various physiological functions in living organisms.

Amino acids can be divided into the following categories according to their location and function in proteins

1.Essential amino acids

9 amino acids that the body cannot synthesize by itself or the synthesis speed cannot meet the needs, and must be ingest through food, including lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, valine and histidine (infants also need histidine).

2.Non-essential amino acids

The human body can synthesize by itself and does not need to obtain directly from food, including glutamic acid, aspartate, alanine, serine, glycine, proline, cysteine, etc.

3.Conditional essential amino acids

Under specific conditions (such as disease, stress), the human body's synthetic ability is reduced, and additional supplements are needed, such as arginine, glutamine, etc.

Amino acids are also widely used in the field of skin care, as skin care ingredients, they mainly have the following effects

1.Moisturizing

Some amino acids such as glycine, alanine, etc. have good hygroscopic properties, which can help the skin retain moisture and enhance its moisturizing ability.

2.Repair

Such as arginine, glutamic acid, etc. participate in the repair and regeneration process of skin cells, promoting wound healing.

3.Anti-aging

Certain amino acids have antioxidant effects that can help fight free radical damage and slow down skin aging.

4.Cleansing

Amino acid surfactants, such as sodium lauryl sarcosine, are commonly used in cleansing products for sensitive skin due to their mild, non-irritating properties.

Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
