Therefore, seize the favorable opportunity for the temperature to rise, and put shallow water as appropriate when fertilizing(propagation tray). The timely application of fertilizer can stably improve the fruit setting rate of strawberries. The seedling age is about 60 days, there are 10 parietal leaves, the diamond plate is 15cm, and there are 2 to 3 branches for stocking(black plastic plant pots). When stocking, 10 straw ropes are bunched up and gradually inserted into the bottom.

After the water chestnut grows out of the water surface(plug trays), if the density is too high, artificially dense and even seedlings can be taken to prevent the water chestnut from sealing the water surface early and opening it small, which affects the yield. As aquatic vegetables, water chestnuts require different fertilizers from upland crops and require more fertilizer(4 cell propagation trays wholesale). 10 kg, which can come from soil organic fertilizer and chemical fertilizer respectively.
(cheap plant propagation trays manufacturers poland)Except for proper dosage, apply sufficient base fertilizer. Before planting, you can apply 2000 kg of pig manure or decomposed mud manure(gallon nursery pots). When the water chestnut germinates, you can apply 5 kg of urea as quick-acting fertilizer. After flowering, divide it 2 or 3 times and combine it with 2 or 3 packs of strong yield increasers for disease and insect control(nursery plant pots). Potassium dihydrogen phosphate is applied foliar to prevent premature aging.
Production practice shows that the method is: top dressing in stages(gallon plant pot). Topdressing 2 times. The first application was in the first leaf-leaf stage, 10 kg of urea per acre, and the first application was before the lotus leaves were sealed, and 15-25 kg of compound fertilizer was applied per acre. Generally, 5-6 kg of urea and 10-15 kg of compound fertilizers are suitable(6 cell propagation trays wholesale). Dry water is exposed to dry topsoil before blind sowing, and 1 kg of zinc sulfate is added in areas with a lack of zinc.
First apply 250 ~ 300 grams of nitrogen, phosphorus, potassium (15-10-30) full-nutrient water-soluble fertilizer per plant(50 cell seedling trays wholesale), and apply 3-5 kilograms of water or biogas slurry or rotten human and animal manure. Strengthen the management of flowering period and improve the fruit setting rate. Weak trees do not cut(cell propagation tray wholesale). In general, timely topdressing can increase the number of effective flower buds and increase the fruit setting rate.(cheap plant propagation trays manufacturers poland)
Because the strawberry has a shallow root system and is sensitive to the response of fertilizers, urea and compound fertilizers should be the main fertilizers(square grow pots). The amount of fertilizer should not be too large. In addition, in the flowering and fruiting stage, a 0.2% potassium dihydrogen phosphate solution and a 600-800 times solution of a new high-fat film were applied as foliar sprays, which had a good effect on improving quality and increasing yield(12 cell propagation trays wholesale).
However, generally, 1 kg of borax is added in areas with a lack of boron(plastic plant pots wholesale suppliers). At present, for the high quality and high yield of Chinese cabbage, how much nitrogen fertilizer is appropriate? Production practice proves that for every 1,000 kg of fresh vegetables, about 2.0 kg of pure nitrogen needs to be absorbed from the soil, and a total of 5,000 kg of fresh vegetables needs to absorb pure nitrogen(8 cell propagation trays wholesale). Then place the towel in clean water.
(cheap plant propagation trays manufacturers poland)In some remote areas, there may be insufficient nitrogen fertilizer supply, thin leaves, pale tissues, and coarse tissues(flat plastic tray). Fertilization not only affects yield, but also has poor quality. Therefore, the seedling stage is very small, accounting for about 2% of the total, and the rosette stage is increased to about 28% of the nitrogen(18 cell propagation trays wholesale), and the nitrogen absorption amount during the filling stage is the largest, accounting for about 70% of the total.
In most Chinese cabbage production, the actual amount of applied nitrogen far exceeds the required amount(large plastic terracotta pots). Excessive application of nitrogen fertilizer not only results in the thickening of the outer leaves of the Chinese cabbage, poor quality, low yield and quality, but also the large amount of water in the leaves, which is not storage-resistant after harvesting(40 cell propagation trays wholesale). It is easy to rot, and it is susceptible to diseases and insect pests at the later stage of growth.
Nitrogen fertilizer application should be applied in stages, reflecting the former light and heavy(seed starter trays). The amount of chemical nitrogen fertilizer should be reduced under the condition of applying a large amount of organic fertilizer. Application of appropriate amount of nitrogen fertilizer has a good effect on the growth and development of Chinese cabbage(36 cell propagation trays wholesale), is conducive to photosynthesis, and is the key to achieving high quality and high yield of Chinese cabbage.(cheap plant propagation trays manufacturers poland)
