There's a lot of writing on the internet about sunflower growing. The writer always thinks the theory is better than experience! As a result, the young editor was looking for this document
The method of planting sunflowers:
Soils: acacias prefer air-transmitting soils, and, if conditions permit, it is preferable to plant or at least mix grass-breed with grass-breeding, with a slightly more acidic soil ph in the range of 5. 5-6, which is most suitable for the growth of acacias, generally not above 7 because it affects the absorption of trace elements, the soil is not too salty and the soil is washed with clean water before planting。
It is easier for the new root to grow, and once or twice for the leaf to be sprayed, if the temperature is too low, if the northern wind is so high, if the conditions are enough to cover the wind, if the sun is large and growing for three to four days, it should be properly shaded, and it doesn't matter if after four days the sun is not afraid。
Water: water is a big problem! It is important to keep the soil wet for the first two weeks, but not too much water, so that it is easy to tie up the soil, have poor ventilation, and have poor water, especially in cold weather, and then two weeks later to use dry and wet spacing, which means that after one fertilization, it takes longer to dry the soil, with the advantage that it is better to breathe and dry soil that stimulates the roots, which are not good if the soil is wet for a long time
3. Fat water: if ec values 1. 0-1. 2 can be measured, it is best. After the third week, it can be raised to 2. 0, up to a maximum of 2. 5。
At least one leaf must be removed, not just a little bit, but the top advantage or not a white one, and it's important that every pair of neutrons has a bud, and it's not easy to grow when they grow, especially the chicken species。
There are six major problems in growing sunflower:
The best of the earth is charcoal, which, if not, can be mixed with so-called nutrients in the market, or with coconut condensation, leeches, pearl rock, but generally without clay, because of the easy choice of pelvis, which can be used by eight of them, as well as the normal 15-centriton basin, where the penner recommends two, so that it is easy to be full and flowers can come in advance, such as a basin above 20cm, and three are recommended。
A week after the seedlings were planted, water was stopped from the leaves. It is most appropriate to keep the soil moist, and the soil should be dryed properly once a week, so that the roots are not easily yellowed and the roots grow stronger。
The usual levels of grass-grain, nutrients and horticultural soil are between 6. 5 and 7. 5, which are neutral soils, while the most appropriate values are between 5. 5 and 6. 0 for acacia. Conditional florists can regulate soil alkalinity by adding a few lemonic acids, so that the flower is growing at a faster rate than has not been adjusted, and because other nutrients, such as magnesium, are more readily absorbed under low ph, the seedlings are healthier。
When the sunflower is five to six active leaves, the roof is sprung with a boom, one leaf is removed and four to five large leaves remain. Upon top, enhanced management of fatty water will generally result in 3-4 strong and side branches, with a 15-centimeter collection of flowers. If two plants are planted, six to eight branches can be obtained after the first hit is completed. If you're a desperate guy, you can even make it grow, but it's better to take a second take, when the side branch grows three to four leaves, then take the core off, and when you're done with the second take, you'll get a full stretch, and then you'll get a good harvest in a month。
As asymptomatic diseases tend to occur at temperatures below 18 degrees at night, generally there is no disease in the summer sunflower. It is the cold weather of winter that makes asymptomatic disease the most vulnerable. The solution is that, each month, the presence of bacterial clean-up in the soil can be significantly reduced. As for the pests, it is not usually the case, but be careful to observe, especially on the back of the leaves, not to be soft, to kill if there are little animals such as red spiders and steeds
The sunflowers don't like the heat if it's too high, like shanghai summer. Most species of sunflowers, new leaves turn yellow at night, and some of them, even new leaves turn white, when the sunflowers basically stop growing, mainly because the sunflowers are dark at night, they breathe well, they consume too much nutrients, they cannot accumulate, so the leaves turn yellow, so the measures we take are just a proper shade in the summer, after 5 p. M., some fatty water, and green in september
