The evaporation is large, downy mildew is caused by the infection of cabbage downy mildew(seed starting trays), and the seedling disease is viral disease and downy mildew. Insect pests are aphids, cabbage caterpillars, diamondback moths and rapeseed meal; virus diseases are mainly caused by turnip mosaic virus and tobacco mosaic virus. When the climate is high and dry, the virus is transmitted by migration(bulk 14 gallon pots). Therefore, prevention and control of aphids is an effective measure to prevent viral diseases.(cheap 3.5 inch square plastic plant pots wholesale)
The prevention and treatment method is to use disease-resistant varieties(square grow pots), seed disinfection before sowing, and the early stage of the disease, spraying alcohol, Bordeaux mixture, carbendazim, chlorothalonil, daisen zinc, and profitable fungicides. After the sowing and covering operation, the insect pest control can be sprayed with 40% omethoate emulsion 1000 times solution, 20% bifenthrin EC 2000 times solution, worm water agent 1500 times solution(bulk 10 gallon pots), and green water agent 10001500 times solution.
After 2 leaves and 1 heart, the worms occur in large quantities(cheap plastic plant pots bulk). In addition to chemical control, weeds should be removed, shading should be cooled, and the nursery environment should be improved. Spray water for 1 to 2 foliar sprays, and spray 0.2% to 0.3% urea and potassium hydrogen phosphate. It is the pruning before the spring spring shoots of the second year after the lemon picking(7 gallon nursery pots bulk). In the northern region, it is easy to prun as soon as the spring temperature rises and before the spring shoots sprout.
(cheap 3.5 inch square plastic plant pots wholesale)In summer, the temperature is high, and the early leaves are light green and small lesions(nursery plant pots), which gradually expand into yellow-green irregular lesions, and white moldy on the back of the leaves. The shading net is not covered for 3 to 5 days before planting, so that the vegetable seedlings can be adapted to exercise under natural conditions(5 gallon nursery pots bulk). After 128-well seedlings are broadcast for 18 to 20 days, the seedlings can be colonized when they grow to 4-5 true leaves.
Since the disk is covered with a white mulch and other materials(large plastic terracotta pots), it is important to emphasize that the square matrix is better than the circular one, because in the same number of cells, the square is larger than the circular one. The nutrient soil or matrix is more, the top of the square caucus is more inclined, and the root distribution is more uniform(3 gallon nursery pots bulk). The roots of the circular cuffs are heavier, and the growth after colonization is not as good as the square, so the square shape can be preferred.(cheap 3.5 inch square plastic plant pots wholesale)
Or put it on the nursery bed frame and cultivate 3 strong and evenly distributed main branches under the cut(plastic plant pots wholesale suppliers). It is generally believed that there are fewer main branches, more branches, and the distance between the main branches and the auxiliary branches must be reasonable. Secondly, after the rod is set to grow to 20 to 30 cm each time, the top is removed(2 gallon nursery pots bulk). The lemon tree pruning is mainly divided into two periods, which can be trimmed in winter and spring.
(cheap 3.5 inch square plastic plant pots wholesale)Another pruning period is the growing season, which is after the lemon spring shoots are extracted and before the fruit picking(plastic plant trays wholesale). It is divided into summer pruning and flowering pruning. The main purpose is to control the growth potential of its shoots and promote fruit growth and development. The flowering period is mainly to remove some of the leafless flowering branches, reduce the amount of flowers and nutrient consumption(gallon pot), and achieve the purpose of fruit preservation.
