How to grow Trifolium repens

Clover can be planted in a large area by sowing, you can choose to sow the soil before sowing, turn it over once, and then sow, cover the surface of the seed with a very thin layer of soil, and new seedlings can grow in about half a month. in addition, the self-sowing ability of clover is very strong, it can be harvested many times after sowing in a year, and new plants can grow continuously, which can maintain a good coverage rate.

Planting method of Trifolium repens L.

1. Soil preparation and fertilization. Because the seeds of Trifolium repens are relatively small and thin, the competitiveness itself is weak, coupled with the existence of weeds in the surrounding environment, so the growth will certainly be relatively slow. Prepare the soil before planting the seeds to get rid of the weeds. At the same time, to apply basic fertilizer, you can apply about 25 kilograms of calcium, magnesium and phosphate fertilizer per mu. For some soils, such as stable manure for those lacking organic matter, 50 kg of lime can be applied to soils with excessive acidity.

2. Seed treatment. The seeds were treated by mechanical methods or immersion and corrosion in concentrated sulfuric acid before sowing. Soak in sulfuric acid for 20-30 minutes, remove it and rinse with clean water. Dry it before sowing. In addition, clover rhizobium can be used to mix seeds before sowing, which is beneficial to seed germination and plant growth.

3. Soil selection. Trifolium repens seeds do not have high requirements for soil, it is best to choose soil rich in calcium and humus and good drainage, which can provide more nutrition and good growth environment for seeds.

4. Seed planting. Sowing time and methods can be sowed in spring or autumn, single sowing, mixed sowing, strip sowing or sowing.

5. Sowing depth. The depth of planting is about 1-2 cm, not too deep, otherwise it is not easy to emerge seedlings. Of course, appropriate adjustments should be made according to the texture and dry and wet conditions of the soil.

Points for attention of Trifolium repens

1. Trifolium repens enters the dormant period in summer, and the leaves will wither to a certain extent. Flower friends, do not worry, do not rush to water and fertilize, just let it rest quietly. After summer, the white clover grows again.

2. There are many diseases of Trifolium repens, such as powdery mildew, spore anthracnose, gray mold, stem spot black stem disease, shell bisporo leaf spot, downy mildew and rust, so weeding should be done frequently and disinfection should be turned over before sowing.

Common insect pests of Trifolium repens and its control

1. Leafhopper pests. Control method: check in late April, if larvae are found, it can be 1500 times of fenitrothion or 2000 times of pyrethroids. Spray evenly, the leaf surface, the back of the leaf, and the plant should be sprayed inside and outside.

2. White pink butterfly pest. Control method: it can be sprayed and killed by spraying cyanobacteria in the larval danger period. You can also sprinkle 2.5% trichlorfon powder when the dew is not dry in the morning.

3. Land tiger insect pest. Prevention and control methods: in addition to the commonly used venom trapping and killing, carbofuran granules can be used for ditch or hole application, with a dosage of 1500-2000 grams per mu. The drug has a long residual period and can be protected from harm 7-8 weeks after application.

4. Spodoptera litura pests: control methods: the most suitable growth temperature of Spodoptera litura is 15-25 ℃, which can be used in the evening or morning, 2.5% trichlorfon powder and 5% fenitrothion powder 22.5-30kg/ ha, or 50% trichlorfon crystal 1000-1500 times, 50% dichlorvos emulsion 1000-2000 times, 50% fenitrothion emulsion 1000 times 50-100kg/ mu.

The planting method of Trifolium repens is relatively simple, in the planting treatment, we need to do a good job of land selection, soil preparation, and then disinfect the seeds. In the later stage of planting, it is necessary to strengthen the prevention and control of diseases and insect pests, only in this way can it grow healthily.
