The number of buds and bolls falling off has been greatly reduced(200 cell seed trays). If the traditional method of fertilization, often can not meet their needs, resulting in poor nutrition growth and premature aging. In addition, due to the introduction of insect resistant genes(10 gallon nursery pots), the disease resistance ability of insect resistant cotton decreased, and it is easy to cause diseases such as red leaf and stem blight.

Generally, 25-30kg of urea and 10kg of potash should be applied per mu(15 gallon nursery pots wholesale). Potassium fertilizer has the function of enhancing cotton's resistance to adversity and the effect of disease prevention. If the application of N and P fertilizer is increased blindly and the application of organic fertilizer and K fertilizer is ignored, not only the cost of fertilization will be increased(greenhouse trays), but also the cotton will be premature or late maturing, which will have a great impact on the yield and quality.(plastic 1 gallon plant container manufacturer)
According to the characteristics of fast and concentrated flowering and Bolling of insect resistant cotton, 2 / 3 of the boll fertilizer can be applied at the initial flowering stage(5 gallon nursery pots), and the remaining 1 / 3 can be applied after 15 days or so, which can not only meet the needs of continuous flowering and Bolling of cotton, but also effectively avoid the excessive growth and premature aging of cotton plants(plastic gallon containers). Therefore, it is necessary to apply more potassium fertilizer to insect resistant cotton.
Generally, the reproductive growth is vigorous, the bolls are early and many, and the peak of fertilizer demand is fast and fierce(1 gallon nursery pots bulk). It is necessary to increase the application of organic fertilizer and potassium fertilizer, and reduce the operation of nitrogen and phosphorus fertilizer as follows: Apply about 3000 kg of organic fertilizer and 10-15 kg of potassium fertilizer per mu(buy plastic plant pots). When potted evergreen, it needs to apply sufficient base fertilizer during potting.
(plastic 1 gallon plant container manufacturer)In the later period of cotton growth, the absorption capacity of root system decreased, and it was easy to cause premature senescence, so top dressing was needed(7 gallon nursery pots). Foliar topdressing has the advantages of simplicity, quick effect, good effect and fertilizer saving, which can save 2 / 3 of fertilizer compared with soil topdressing(plastic nursery containers). Evergreen, like many potted flowers and plants, also prefer a fertile soil environment.
Now, has this "water culture wind" come to your home? The common cultivation method of evergreen is soil(72 cell propagation trays wholesale). Can evergreen be cultured in water? From the perspective of environmental protection, the roots of hydroponic plants are less likely to grow bacteria than those of soil cultured plants, and they look more "eye-friendly"(3 gallon plastic pots). Of course, evergreen can also be cultured in water, but if the care is not proper, the survival rate is relatively low.(plastic 1 gallon plant container manufacturer)
Prepare a suitable transparent vase and wash it(25 gallon nursery pots). During hydroponics, do not immerse all roots in the water, but leave 1 / 3 or 1 / 4 of them on the water surface. During hydroponics, change water every 3-4 days. When evergreen grows new roots, remove the old ones in time(nursery plant pots wholesale). After new roots grow, water can be changed every 15 days, and foliage plant nutrient solution can be added, but it should not be changed completely.
(plastic 1 gallon plant container manufacturer)In recent years, a large number of insect resistant cotton introduced from all over the country has effectively controlled the harm of cotton bollworm(plastic plant pots). Specifically, wash the soil on the root and remove the withered root. If we want to cultivate evergreen by water, we should start from the following aspects(2 gallon pots for plants). Generally, the boll stage is the most vigorous growth and development period in cotton life, which needs the most fertilizer.
