2. Soil preparation: when preparing the soil, it is necessary to dig more than 20cm deeply and apply rotten farm manure 800~1000kg/ mu. Make a bed or bed, 1.2m wide.

3, sowing seedlings: spring sowing at the beginning of May, strip sowing mainly, row spacing 20cm, deep 1cm, soil thickness after sowing about 0.8~1.0cm, slightly suppressed, sowing amount of 250~300g/ mu, when the temperature reaches 20 ℃, it can sprout and emerge in 15 days, and the emergence rate is up to 80%. Transplanting in late May, row spacing 30~40cm, seedling 7-8 pairs of leaves pick out the heart, promote multi-branching, and blossom in July-August. Autumn sowing is carried out in late August, covered with grass or leaves to prevent cold in winter, planted in early May of the following year, and flowered in July.

4. Illumination: Xieqiu plants like light and are slightly shady. They generally grow in low mountain sparse forests and shrub meadow shady wetlands. Special attention should be paid in the process of planting.

5. Temperature: it is cold-resistant, and the temperature suitable for seed germination is generally about 20 degrees.

Prevention and control of diseases and insect pests

1. Leaf spot. Prevention and control methods: increase the application of base fertilizer to ensure the fertility of the soil and enhance disease resistance. It is found that the diseased leaves are removed in time to prevent and control the further spread of germs. if the disease is more serious, it should be disposed of in time. Before the onset of the disease, you can spray 75% chlorothalonil wettable powder 500,600 times liquid or spray 75% chlorothalonil wettable powder 1000 times liquid plus 70% methyl thiobacillus wettable powder 1000 times liquid for prevention and treatment.

2. The common pests include shell insects, aphids, leaf roll moths, thrips and so on. Shell insects can be sprayed with 1000 times of omethoate EC, 4000 times of potassium permanganate for thrips, 2000 times of pyrethroid EC and 2000 times of rotenin, etc.

Xieqiu Luo usually chooses spring or autumn when planting. Site selection and fertile land need to be done before planting. Management needs to be strengthened before planting, and timely pruning and fertilizing are necessary conditions to ensure its growth.
