During the growth period of rape, it is necessary to apply fertilizer and water frequently to make the seedlings more robust. In the northern winter, it is also necessary to cover a layer of organic fertilizer, which is mainly used to keep warm and prevent frostbite. Rape also has many uses. It is edible when the rape bud is not open. Because the seeds will swell when they absorb water on the paper towel, if they are placed densely, it will affect the germination of seeds.

Pine nuts are spread by squirrels storing winter food. Generally, in autumn, in order to store enough food, squirrels will take their favorite nuts away, bury them in the ground or store them in tree holes, so that they can sprout again in spring. Pine nuts are rich in unsaturated fatty acids, which can promote children's growth and development, but also conducive to the recovery of the body after illness.

After finishing the above work, we need to put the seeds of Catharanthus roseus in a place with scattered sunlight for maintenance. We should not put them in the sun. We need to open the bag for half an hour every day to supplement the air in the plastic bag. During this period, we don't need to add water, because the water is very small in a sealed environment. When there are buds, we need to transplant the germinated Catharanthus roseus into the soil in time.

It can often be seen beside the country roads, because the seed has a thin layer of thorns on its surface, which will stick to the clothes if it is careless. Radishes are planted in different varieties according to different seasons. Generally speaking, radishes are planted most in autumn and winter. The best temperature for radish germination is 20 to 25 degrees Celsius, so its germination rate will be improved.

Many people are unfamiliar with coriander, but when it comes to coriander, everyone is familiar with it. It can also be sown in autumn, but it is best to rub the seeds when sowing, so as to improve its budding rate. Wheat is divided into spring wheat and winter wheat. Winter wheat is usually planted from September to October of each year, and then harvested from April to May of the next year. The germination of the seeds after germination was about a week earlier than that of the normal seeds.

Spring wheat is usually planted around the Spring Festival every year and harvested from August to September. The peak period of wheat planting is from September to October every year, but the specific time varies from region to region. Precautions for planting wheat there are many things to pay attention to when planting wheat. Before planting wheat, the seeds need to be dried for about three days, which will speed up the germination of wheat seeds.

When selecting wheat seeds, we must try to select high-quality seeds, and dry the seeds to wake them up. We need to select those plants that are full. When selecting, we can pinch them. If they are solid, it means that the seeds are full. Then soak the lavender seeds in clean water for 12 hours, which is conducive to improving the germination rate of lavender seeds.

Of course, after it sprouts, the temperature requirement is not very high. It can grow even at a temperature of minus two degrees Celsius. To prepare pot soil for planting lavender, you can choose a larger flower pot, which is conducive to the growth of lavender. The soil needs to choose fertile soil with good drainage. Generally, we use sand and vermiculite, which has good drainage and is conducive to the growth of lavender.

Can old seeds still be used? Different seeds have different storage periods, but we believe that the life of seeds is closely related to the storage environment. Seeds such as coriander, tomato and pepper can be preserved for 2-3 years or 4-5 years. Some seeds have a special service life. For example, celery needs to be stored for three years, so the germination rate will be higher. A basket full of culture medium can sow about 100 seeds.

Carnations can be sown all year round as long as the sowing temperature is appropriate. If the temperature cannot be guaranteed, it is best to sow carnations in spring and autumn every year, because the temperature in these two seasons is more suitable for the growth of carnations. At this time, the germination rate of carnations sown is also the highest. When the germinated seeds are planted in the soil, the seedlings can grow in twoorthree days.

Preparing soil carnations like fertile, breathable and well drained soil, so we can mix soil containing humus with peat soil. Such soil has very good drainage and permeability, and there are sufficient nutrients for carnations to grow. It is very suitable for planting carnations. And like leek, cabbage and other seeds, it is best to use the new seeds of the year, otherwise it will affect the germination rate.

Before sowing, we should first thoroughly water the soil, and then spread the prepared carnation seeds on the surface of the soil. When sowing the seeds, do not let the carnation seeds be too dense so as not to affect the germination, and then spread a layer of soil. The soil should not be too thick, otherwise the carnation seeds are difficult to germinate, and then put them in a cool and ventilated place to wait for the carnation seeds to germinate. During this period, we should keep the soil moist. We can spray water on the soil with a watering can.

At the beginning of sowing, we first sprinkle the seeds of lavender on the soil, and then cover a layer of soil. The covered soil should not be too thick to avoid affecting the growth of lavender, and then seal the flowerpot with plastic film, which can reduce the evaporation of water and help maintain the temperature. It will make Lavender grow faster, and then put it in a cool and ventilated place for maintenance.

How to spread the seeds of Xanthium sibiricum both humans and animals play a very important role in the process of spreading the seeds of Xanthium sibiricum. When the rape is mature every year, many pods will be produced after the rape flowers fall completely. When the pod is about to crack, break it with your hands and take out the seeds inside. Then the seeds will be properly dried for a period of time. After a few days, they will be collected and stored for sowing next year.

The effect is very good, the root system is developed, and the seedlings are neat and strong. Generally, the seedlings can be raised and transplanted to the pot within 40 days. The pot culture medium with a length of 50 cm and a width of 30 cm can be used for pot planting. There are 200 pot cups in a pot. One seed can be sown in each pot. Generally, it can take root and germinate after 40 days. When 3~5 true leaves are grown, it can be transplanted together with the culture medium. This method has better effect than field sowing and plastic box seed sowing.

Before planting rape flowers, we usually plant them in autumn. Before planting rape flowers, we first apply fertilizer on the cultivated land selected in advance, which can be either chemical fertilizer or farm manure. After the fertilizer is applied to the soil, plough it with a tiller to fully mix the fertilizer with the soil, which can make the soil more fertile and nutritious, let air into the soil, and help the breathing of seed buds.
