Introduce the use of foliar fertilizer and several commonly used topdressing methods for reference by farmers(flat plastic tray). In addition to applying the base fertilizer, they should be sprayed with 1~2% urea (ammonium sulfate) solution in the seedling stage, middle and late stage, once every 7~10 days, even spray 2~4 times, it can accelerate leaf seeding and rapid growth(gallon nursery pots), and it can save cost and increase nitrogen fertilizer utilization rate, which is 20~30% higher than soil application.
(large 20 gallon nursery plant pots for sale)Vegetables such as melons and fruits have a relatively balanced need for nitrogen(plastic grow pots), phosphorus, potassium and trace elements (mainly boron, zinc and molybdenum). That is, 1~2% urea water in the seedling stage is added to 3000 times 802 spray. Take strong long leaves(cell trays), use 1~2% urea mixed with 0.1~0.3% boric acid and 1000 times plant power 2003 solution for 2~3 times (about 7 days each time), increase fruit setting rate and prevent "flower" Unreal."
Leafy vegetables need more water and fertilizer during the whole growth period(greenhouse supplies pots). The vegetables such as stems and stems need more phosphorus and potassium fertilizer than nitrogen fertilizer during their whole growth period, especially in the middle and late stages. If the potassium fertilizer is insufficient, the organic nutrients produced by the leaves will be transported slowly and less to the roots(gallon plant pot), and premature aging and leaf wither (or brown spot).
(large 20 gallon nursery plant pots for sale)Fertilization of melons and fruits should be more scientific(wholesale greenhouse pots). According to different types of vegetables, scientific and rational selection of foliar fertilizer is very important for vegetable growth. In the autumn, the climate is relatively cool. The temperature in winter is generally low. At this time, the temperature is generally 16 °C. In the result period, 1~2% urea aqueous solution or 0.2~0.3% potassium dihydrogen phosphate solution is sprayed(propagation tray), once every 7~10 days, a total of two or three times.
After sowing or planting vegetables(seed starter trays), in order to meet the needs of their growth and development, more top dressing is often required. In addition to applying a small amount of nitrogen fertilizer in the seedling stage, more potassium and phosphate fertilizers should be applied in the middle and late stages. Many people want to know how red diamonds are fertilized(plug trays). The first thing to know is that red diamonds have different methods of fertilizing every season.
(large 20 gallon nursery plant pots for sale)If the temperature does not reach above 16 °C, do not fertilize the red diamond(square nursery pots). If it is reached, it can be applied to a small amount of urea or a small amount of flower-specific fertilizer once a week. In the summer fertilization, it should be noted that when the temperature reaches 30 ° C or above, the fertilization should be stopped in time(104 cell trays bulk). And take some facilities to cool down and humidify, to prevent the red diamond from being hurt due to high temperature.
Avoid the damage of red diamonds caused by high temperature and low temperature(black plastic plant pots). When the temperature at this time is between 16 ° C and 30 ° C, the frequency of fertilization can be appropriately increased. Can promote the growth of red diamonds. Fertilizer is mainly based on flower-specific fertilizer, and some urea or potassium dihydrogen phosphate can be added to fertilize(72 cell seed starting trays). The frequency can be increased to 3 to 4 times a week.
