Bagging of Red Fuji Apple Flower Pest Control

In mid-April (before flowering)

Control objects: 1. Powdery mildew, rust, and moldy heart disease. 2, cotton aphid, Lycium barbatus, leaf roller moth, green-lipped carp, Cornell mealybugs and so on. 3, gold pattern fine moth. 4. Hawthorn red spider, white spider 5, make up the boron increase the fruit setting rate.

Control measures: 1, 40% of Ninth 8000 times or imported 50% of carbendazim powder 800 times or 70% of ketamine 800 times or DuPont Fuxing 8000 times. 2, 48% of the Reef 1500 times or 1500 times the An Minle, (put the wall bee park, put the bees before 2 to 3 days before the spray Leben, safety against wall bees). 3, stuck die 2000 times. 4, 5% Adimensional salt 6000 times. 5, can be Boron 6,000 times or 1200 times boron spray.

Note: 1, Reuters prevention and treatment of apple ramie have special effects, spray again before flowering, spray after Xiehua again, can basically eliminate the damage of the year, and at the same time, governance of tumor lice, apple leaf roller moth, green clerodendrum, Conrad powder Pelicans and other wintering pests. 2, boron and manure can be boron-soluble, easy to absorb. 3. Rayleigh Liquid Boron is produced by Beijing Leili Agricultural Chemical Co., Ltd. 4, 500 times before flowering Rui frog spray the ground, can control a variety of underground pests.

From late April to early May (7-10 days after Xiehua)

Control objects: 1, rotten rot disease, anthrax, spotted defoliation, black pox, mold heart disease. 2, cotton Aphid, apple leaf roller moth, green-yellow grasshopper, cotton bollworm, Cornell mealybug. 3, apple red spider, hawthorn red spider, two leafhopper (white spider). 4, calcium deficiency bitter pit disease. 5, Bao Baobao fruit surface.

Prevention and control measures: 1, sterilization formula: green light + dragon light bracket 800 times. 2. 48% of Swiss frogs 1500 times or 50% 1500 times. 3,5% Dimensional salt 6000 times + powder 4,000 times or 6,000 times. 4, plant power 2008 calcium 2000 times. 5, control locusts can be used to 3,000 times. 6, plant power 2008 calcium 2000 times, can be boring 6,000 times or 1200 times boron.

Note: 1, Apple Xiehua before bagging, is the most critical time period for the prevention and treatment of apple disease, should be continuous spraying 3 to 4 times green big students, while the appropriate mix of chlorpromazine or bactericide, can effectively control Ring rot fruit disease, anthrax, spotted deciduous disease, black spot disease and red spot disease of bagging apple. 2, after the flower is still a key period for the prevention and control of overwintering insect pests, spray frogs can simultaneously cure cotton worms, leaf roller moths, green-yellow larvae, cotton bollworm, Cornell mealybugs and other pests. 3, small leaf roller moth light garden, can be used to solve both the music, leaf curling heavy park can be used for farm music. The leaf orchard is particularly serious in the orchard. 4, Apple Xiehua before bagging is the peak period of boron, spraying can be significantly increased the apple can significantly increase the apparent light. Boron supplementation here can increase fruit setting rate, promote calcium absorption and promote flower bud differentiation.

An Analytical Balance (often called a "lab balance") is a class of balance designed to measure small mass in the sub-milligram range. The measuring pan of an analytical balance (0.1 mg or better) is inside a transparent enclosure with doors so that dust does not collect and so any air currents in the room do not affect the balance's operation. This enclosure is often called a draft shield. The use of a mechanically vented balance safety enclosure, which has uniquely designed acrylic airfoils, allows a smooth turbulence-free airflow that prevents balance fluctuation and the measure of mass down to 1 μg without fluctuations or loss of product.[citation needed] Also, the sample must be at room temperature to prevent natural convection from forming air currents inside the enclosure from causing an error in reading. Single pan mechanical substitution balance maintains consistent response throughout the useful capacity is achieved by maintaining a constant load on the balance beam, thus the fulcrum, by subtracting mass on the same side of the beam to which the sample is added.[citation needed]

Electronic analytical scales measure the force needed to counter the mass being measured rather than using actual masses. As such they must have calibration adjustments made to compensate for gravitational differences. They use an electromagnet to generate a force to counter the sample being measured and outputs the result by measuring the force needed to achieve balance. Such measurement device is called electromagnetic force restoration sensor.
