1, variety selection

Fennel varieties can be roughly divided into three kinds, fennel, fennel and bulb fennel three kinds of fennel varieties, fennel varieties are high, the growing period is shorter, but the aroma is lighter. Fennel is a little shorter than fennel, but the flavor is heavier and tastes better, and we generally grow fennel here. The last is bulb fennel, bulb fennel in the growth of a certain stage of its branches and stems will hold together, but the yield is the highest, the flavor is also the lightest, no matter which varieties can be sown in the fall, so we can choose their own favorite varieties in the sowing can be.

2, the whole ground fertilization

Fennel on the growth of environmental requirements are relatively low, but to make fennel yield high, it is best to choose to plant in fertile soil, good drainage performance of the sandy soil, in the planting of fennel before the bottom of the fertilization, the bottom of the fertilization is best to choose the fully rotted farmyard manure, in the bottom of the fertilization after the application of a good deep ploughing can be planted.

3, planting management

The seeds of fennel are particularly small and light, and direct sowing can easily lead to uneven planting, in order to make the fennel planting more uniform, you can add an appropriate amount of sand to the seeds, which will make the planted fennel particularly uniform. In order to prevent watering after planting the seeds all washed together, it is best to water enough before planting, after spreading the fennel seeds in the top and then covered with a layer of film, and sprayed with water in the morning and evening to improve the fennel seedling rate.

4, planting fennel is generally selected in the spring and fall, spring planting in March-April, fall should be selected in August-September. The warm climate is very helpful for seed germination. If planted in the summer, high temperatures and strong light will affect the development of seedlings. Winter temperatures are too low for the seeds to root easily after planting.
