In june, it was the golden window that planted the sunflower. It's hot, it's hot, it's hot, it's hot, it's hot, it's hot, it's hot, it's hot, it's hot. They sell a dozen pounds at the city's restaurant, they grow their own food, they don't have to buy it all summer。
But a lot of freshmen grow acorns, and the first step is to plant the seeds -- the seeds don't grow for ten and a half days, they're taken apart and they rot in the ground. The root of the problem is in the selection, leaching and seedling chain, where one step at a time is wrong and the yield is half as low。
I. Selection: don't lose on the starting line
The autumn seed shell is hard and thick, with its own wax, which is its instinct for self-protection, but it is also the source of the seed problem. Selection is the first step, with three main points to remember。
First, buy the right varieties. It is common for the market to have yellow and red sunflowers, which are soft and high-yielding and suitable for family cultivation and bulk production, and red berries, which have high but slightly lower luminous content. Either way, it is important to look at the date of production on the packaging - the normal two-year lifetime of the acorn seeds and the fall in the masonry rate. Don't rush it all down, grab a little test, have a background。
Second, eye-screening. The seeds are poured on white paper before they are soaked, and they are removed from the plume, the moth, and the moldy particles, leaving only those which are full and of equal colour. This step seems to be a simple one, and many people are in trouble, and half of it goes on as “duds”。
Third, sunburn activated. The selected seed stand is tanned for one to two days in the sun, not more than two centimetres thick, with two or three strokes in the middle. Sunshine can break the seeds and kill parts of the surface of the fungus. It can also produce tiny cracks in the skin and lay the foundations for subsequent leaching。
Ii. Leaching: the temperature of water tends to vary
Leaching is part of a lot of rollovers. Autumn skins are hard, do not impregnate direct seeding, produce slow and unsophisticated seedlings, have the same size, small, passive post-management. But leaching is not just water; it is the wrong way to bubble seeds。
Water temperature is the primary key. The most prudent method is to impregnate the seed with warm water: 50 to 55 degrees celsius, which is about five times the size of the seed, while pouring the water with chopsticks, so that the seed is evenly heated. Water temperature decreases naturally and continues to soak, with a total duration of 8 to 12 hours. The temperature of water is too high to burn embryos, the temperature of water is too low to soften the skin, and 50 degrees is a safe and effective zone。
How much is it going to be? Scratch the seed with your finger, grow the skin soft, but it doesn't fall off, and the seed clearly inflates the water, and that's the state. Water is exchanged once or twice and water is kept clean at all times. It's hot in the summer, it's bad for the bubbles, don't throw it in the water all day。
Another practical technique is impregnation. Leaching with a 1% small sodium solution or polybacterial soluble solution can both soften the skin and kill the seed-carrying fungus and prevent sudden fallout and desolation. However, when impregnated, the agent must be washed with fresh water and rebreeded, and the residual agent inhibits the bud。
Iii. Treasure: the need to keep the air wet
It is also possible to sow well-impregnated seeds directly, but they are then sprouted, are produced quickly and in a high degree of integrity, and can pre-empt the bad seed that does not germinate, without waste。
The seeding method is simple. Find a clean gauze or a kitchen paper towel, so that it can be soaking with warm water that it doesn't drop water, that the seeds will be laid on it, covered with another layer of wet cloth, and placed in a plate or in a preservation box. And then put it in warm places, 25-30 degrees centigrade. The natural temperature in june is almost adequate, and indoor temperatures are sufficient, with no deliberate warming。
Check at least twice a day. The gauze was sprayed in time to keep it wet and the molded seeds were immediately picked out to prevent infection. There is another detail that is often overlooked: the sprout environment needs to breathe, not be suffocated in plastic bags, and the lack of oxygen suffocates seeds。
Lou white can sow. In general, two to three days, the seeds display a small white sprouts of no longer than half a centimetre, which is the best time to sow. The sprouts are too long to break when seeding, and they have to pay. If it rains or is poorly prepared, it is possible to keep the white seed in the shade and control the water “crawling”, but at most one day, it is difficult to grow。
The seed must be deep. Autumn seeds have a general top soil capacity of about two centimetres deep, each with two seeds, a centimetre of thin soil, and a light repression and water. The soil is wet, but not water, and the temperature is above 20 degrees. Small seedling arches can be seen in five to seven days。
The june sunflowers were grown in time, but not yet. The three steps of seed selection, leaching and sprouts are rounded together, and the drop rate is stuck at the same time. It makes sense to keep these details in place, so that they are strong enough to water and fatten them. After all, how many acupunctures can be picked in the fall is decided from this moment when the seeds are now baking。
