1. Pre-harvest Management 1 Trim the ears. First go to the soft tip, cut off the 1/4-1/3 portion of the ear, pickle the unsweetened, juicy, soft, and easily dehydrated fruit, then remove the unripe, poor-quality, low-sugar green and damaged grains. Diseased grains. 2 skillful fertilization. One month before harvesting, nitrogen fertilizer was stopped and more phosphorus and potassium fertilizers were used to increase sugar content and storage stability. 3 prevention and treatment of diseases. When the fruit starts to be colored, spray 800 times of tumefait, 600-800 times of carbendazim, or 800-1000 times of seoxe once every 10-15 days. 4 strictly control the water. Stop watering and eliminate waterlogging within 15 days before picking to improve quality and storage. 5 Spray hormones. In order to prevent shredding and fruit stem shrinkage during storage, spray 0.2%-0.4% borax for 15-45 days before harvest, and spray 0.006%-0.01% qinggansu 15 days before or 3 days before harvesting. Spray 0.005%-0.01% naphthalene acetic acid plus 0.0001% of Qingxin. 2, harvesting and harvesting standards. 1 Fully matured. Coloring is good, the tissue is full, and the peel, fruit powder and wax are thick. 2 Harvest time. Choosing from clear, low-temperature mornings or evenings, harvesting is not recommended for rainy or foggy days. 3 harvest method. After cutting with scissors, trim the ears and place them in cartons or baskets lined with 3-4 layers. The containers should be light. It is advisable to put 5-10 kilograms, and the covered paper is pre-cooled. 3, pre-storage processing grapes in -1 °C -0 °C, relative humidity 90% -95%, oxygen 2% -45 and carbon dioxide 3% -5% of the appropriate storage conditions, generally can be stored for about 5 months. Drug treatment before storage, right antiseptic rotten: 1 heavy sulfite release method. 0.3%-0.6% of the weight of the grapes were weighed respectively as sodium bisulfite and anhydrous silica gel. The two were well mixed and then distributed in several small bags and dispersed in the grape box (the medicine bag was separated from the paper between the fruits). Then use the wrapping paper to seal the grapes and the medicine bag in the box, and change the medicine bag every 30-45 days. 2 sulfur fumigation method. The crushed grape vines were piled into pods and covered with plastic masks. They were ignited with 2-3 grams of sulfur per 1 cubic meter. Fumigation for 20-30 minutes, then open the hood to wind, 15 days after fumigation again. Afterwards, fumigate once every 1-2 months. 3 sulfur dioxide gas smoke method. Place the grapes in a box, cover with a plastic cover, and fill with sulfur dioxide gas (sulfur dioxide volume is 0.5% of the volume of the cover). After 20-30 minutes of fumigation, cover and vent. After fumigation once every 15 days, the sulfur dioxide concentration can be reduced to 0.1%-0.2%. 4. Storage methods Storage sites should be first sterilized with 1% formalin, or 1.5%-2% sodium hydroxide, or 10% bleach (dispensed overnight after use) and then stored.

Sunshine condition: apple is the fruit tree, the central health area of the whole year is nearly 3,800 hours, is beneficial to the Apple Fruit coloring. The piedmont apples are red and bright.
Temperature difference factors: ambassador apple nighttime respiration weak temperature gap between day and night, consume less organic matter, the accumulation of organic matter during the day more, that apple store down a large number of glucose sugar candy, etc have better taste. The average diurnal temperature difference between apple and apple is 14 degrees centigrade, and the larger diurnal temperature difference ensures the sweet and delicious characteristics of the apple.
Other factors: frost can make apple blossom and fruit, which can cause frozen flower jelly, which is bad for apple's production. The piedmont apple has been kept at least 167 days without frost for the whole year, which minimizes the influence of apple on yield and quality.
