Planting method and time of clover

The planting time is from March to April in spring or September in autumn. Soak the seeds and germinate: mix the seeds with water and ammonium molybdate in the ratio of 5000 to 1, then soak the seeds for 12-13 hours. Choose soil: farming with pastoral soil, yellow sand and organic fertilizer at the proportion of 5:3:2. Start sowing: sow 18-20 seeds on the soil. Watering and fertilization: appropriate amount of calcium phosphate fertilizer and nitrogen fertilizer can be applied. The suitable temperature for growth is 19-24 ℃.

First, planting time

Clover is suitable for sowing in March-April in spring or September in autumn. if sowing in these two periods, the survival rate will be higher. First of all, you need to select high-quality seeds. Clover blossoms in July-September every year. Clover seeds can be obtained from flowers, and if you find it troublesome, you can also go to the market to buy clover seeds.

Second, seed soaking and germination

During this period, the seeds also need to be treated, and the selected seeds need to be mixed with water and ammonium molybdate in the ratio of 5000 to 1, and soaked for about 12-13 hours, which is helpful to promote the seeds to take root and sprout quickly and prevent diseases and insect pests.

Third, choose soil.

Clover does not have very high requirements for soil. It likes to grow in soils with loose soil, good permeability and water retention, and high fertility. Generally, pastoral soil, yellow sand and organic fertilizer can be mixed at 5:3:2. This mixed soil can promote the growth of clover more robust.

Fourth, start sowing

During this period, you can spread 18-20 seeds on the soil, then cover a small amount of fine soil, spray an appropriate amount of water to keep the soil moist, and then keep it in a cool place for maintenance, wait for 3-7 days before the seeds will take root and germinate. then move it to a sunny place and breed it carefully.

5. Watering and fertilizing

During the growth period of clover, watering should not be too much or too little, otherwise it will affect the normal growth of clover. Generally, if the soil is not dry, there is no need to irrigate, and the amount of fertilization should be well mastered. Calcium phosphate fertilizer can be applied every 10-15 days in spring and autumn. Nitrogen fertilizer needs to be applied every other month in summer, and no fertilizer can be applied in winter.

VI. Suitable temperature

Clover can be placed in a place of sufficient sunshine maintenance, help to promote its growth better, increase its ornamental value, clover suitable for growth temperature of 19-24 ℃, during the period not less than 5 ℃, winter need to move it indoors, give it sufficient sunshine, and then control the temperature above 5 ℃, conducive to clover safety over the winter.

VII. Prevention and control of diseases and insect pests

1. Sclerotinia disease

(1) symptoms: Sclerotinia sclerotiorum is an easy disease of clover. In the early stage of the disease, the leaves show water stains and light brown stains, which will quickly spread to other leaves for a long time, seriously affecting the overall beauty of clover and growing white flocs, which gradually wither the clover and cause the whole plant to die.

(2) Control methods: if clover is found to have Sclerotinia sclerotiorum, the clover should be dug out of the soil, then cut off the rotten roots, replanted in the new soil, and then sprayed with 20% silazolide. Or 40% humulent wettable powder and other agents for control, need to be sprayed every 7 days, continuous use for 3-4 times.

2. White powder butterfly larva

(1) Disease: clover is more vulnerable to the harm of white butterfly larvae from April to October. White pink butterfly larvae will not absorb the juice of clover, but will directly eat the leaves of clover, resulting in the normal growth of clover. It will also reduce its ornamental value, and seriously lead to the wilting and death of the clover.

(2) Control methods: if white butterfly larvae are found to harm clover, all the larvae can be disposed of artificially during this period. It can also be sprayed with 1000 times of Clematis powder or 1000-1500 times diluted with Bacillus wettable powder. It should be sprayed once every 7 days and used continuously for 2-3 times.
