Effective types, appropriate concentrations, application times and times, methods of application, and precautions.
First, the appropriate range
This technology is suitable for apple production areas such as Bohai Bay, Loess Plateau, and the Yellow River old track. It is suitable for the production of main cultivars, but there are slight differences among varieties.
II. Kinds of sparser
1. Chemical sparse agents include lime sulfur, organic calcium and olive oil.
2. There are naphthalene acetic acid, carbaryl, sodium naphthalene acetate and other chemical and fruit thinning agents.
三ã€Stripping agent application technology
1. Chemical sparse technology
(1) Type and suitable concentration. Lime-sulfur mixture: Concentration of lime-sulfur mixture made by the fruit farmer is 0.5 to 1 Baume, and the concentration of the 45% crystal lime used in commercial products is 150 to 200 times; the organic calcium preparation is 150 to 200 times the suitable concentration for spraying. Liquid; olive oil: suitable spray concentration of 30 to 50 grams / liter.
(2) Suitable spraying period. In the early stage of full bloom (ie, 75% to 85% of the central flower is open), the spray is applied for the first time, and the flowering period (ie, 75% of the whole tree is open) is sprayed a second time. Han Fu and other varieties with many flower buds can be sprayed once at the end of the flowering period (ie when more than 95% of the flowers in the whole tree are open).
2. Chemical fruit thinning technology
(1) Type and concentration. Carbaryl concentration is 2.0-2.5 g/l. The naphthalene acetic acid concentration is 10 to 20 ppm; the naphthalene acetic acid sodium concentration is 30 to 40 ppm.
(2) Suitable spraying period. Cevain was sprayed for the first time 10 days after flowering (the center fruit diameter was 0.6 cm) and sprayed the second time 20 days after flowering (central fruit diameter 0.9-1.1 cm). Naphthalene acetic acid and sodium naphthalene acetic acid were sprayed for the first time 15 days after flowering (the center fruit diameter was about 0.8 cm) and sprayed the second time 25 days after blooming.
3. Chemical sparse + fruit thinning technology. In the case of a single sparse flowering effect, a combination of chemical sparse flowering and chemical fruit thinning may be used. The spraying time and appropriate concentration of various chemical sparse and thinning fruit preparations were the same as those of sparse or individual fruit thinning.
Fourth, spray method
1. Select a sprayer with good atomization performance, focusing on evenly and finely sprayed flowers or young fruit parts.
2. The amount of spray, knapsack sprayer control 75 to 100 kg of liquid per acre.
Single Packed Yellow Waxy Corn Cob
For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).
Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
