After September, various late-maturing and late-maturing apples have gradually reached the harvesting stage, and the harvesting of apples will directly affect the output and quality. If harvesting is too early, the fruit development is incomplete, the fruit is light, the appearance is poor, and the sugar content is low; if the harvesting is too late, the pulp flies quickly and the disease resistance performance declines and it is not resistant to storage. Only by appropriate harvesting can we achieve the best food and product quality, and the longest storage life, so as to obtain higher returns. How to distinguish fruit maturity and accurately grasp the best picking time? The author summarized several key techniques for your reference.
To see the vast majority of apple color varieties from apple fruit to maturity during the development process, the color of the peel must be a regular change, that is, peel color gradually changed from dark green to light green or yellow. Some coloring varieties often color earlier, but the peel color is still green. Only when the peel color changes from green to yellow is the performance of fruit ripening. Non-colored varieties, such as Jin Shuai, etc., are usually suitable for picking when the fruit color is slightly yellow.
To see if the fruit of the stalk is truly mature, an detached layer is formed between the base of the stalk and the fruiting stalk, and the fruit is slightly exposed to external forces and falls off.
See the growing period of fruit under normal climatic conditions, different varieties in a region have a relatively solid growth and development period, from flowering to maturity of the time required is also relatively fixed, usually early maturing varieties mature after 60-100 days Medium-maturing varieties are 100-140 days, medium and late-maturing varieties are 140-160 days, and late-maturing varieties are 160-190 days.
See the seed color In the fruit development process, the seed has a law of gradual browning. Cut open the fruit and if the seed turns brown or brown, it is ripe.
See the fruit hardness with the maturity of the fruit, the pulp becomes soft, the hardness gradually decreased, the hardness of the fruit matured relatively consolidated, such as Jin Shuai mature peeling hardness is usually 6.8 kg / square centimeter, Guoguang is 8.6 kg / square centimeter.
Looking at the fruit harvest ripening period and ripening period ripe fruit ripening period can be divided into harvest ripening period and ripening period. Harvest ripening period means that the fruit volume no longer increases, the base of the fruit stem has formed an off-layer; the ripening period of the fruit refers to the period when the fruit is best eaten, for example, the fruit of the late-maturing variety is harvested after 3 to 4 weeks of harvesting. However, the fruits of early maturing varieties are basically the same in both maturation periods, and often require early harvest for storage and long-distance transport.
Look at the weather and market supply and demand of the year. If there is a natural disaster, organize the manpower to properly catch up early. According to the market supply and demand situation in the year, in order to obtain better economic benefits, appropriate early mining or late mining.
In addition, the fruit picking period of the paper bag should be 20-30 days before the ripening period of the fruit. When the weather is sunny, remove the outer bag for 3-5 days and remove the fruit bag. After the fruit is turned to the positive surface for one week, turn the fruit, pick the leaf, and apply the reflective film to make the fruit become pink. You can pick, this is the best picking period for the product color, but the coloring is too heavy to be welcomed by the market.

Types of antibiotics
Thousands of antibiotics have been reported, which can be divided into six types according to their structure:
(1) sugar derivatives, mainly composed of hexosamine derivatives, such as streptomycin;
(2) polypeptide antibiotics, mainly or entirely composed of amino acids, have some characteristics of polypeptides or proteins, such as polymyxin, penicillin;
(3) polyene antibiotics, with multiple double bonds in molecular structure, such as nystatin and amphotericin;
(4) macrolide antibiotics, which are composed of one or more monosaccharides and together with carbon chains form a large aromatic lactone compound, such as erythromycin;
