However, many friends are troubled by the disease prevention and control of peppermint grown in their own homes. Today, I will take you to understand the introduction of the breeding mode of mint, as well as the summary of its disease prevention.

The mode of propagation of mint

In production, it is mainly propagated by rhizomes or seedlings. Peppermint is mainly propagated by separate plants and cuttings, and the stolons of the mother plant are cut off in the first and middle of April and planted respectively. Peppermint can also dig sturdy, white rhizomes, cut into 6-10 cm long, after planting covered with soil about 3 cm, about 15-20 days to sprout. Sowing is carried out in spring or autumn, peppermint takes 80-100 days from germination to flowering, grows slowly at the initial stage after germination, and accelerates after 2-3 weeks. In order to maintain good growth, it is best to update it every year. During the growth period, more nitrogen fertilizer is needed, properly combined with phosphorus and potassium fertilizer, and a large amount of water is needed at the same time. If there is harm to a small land tiger, it should be prevented and controlled in time.

Most of mint is cultivated in open field, and protected field cultivation or both open field and protected field cultivation can be adopted in the north. The cultivation season depends on the local climate and can be cultivated in the frost-free season. The protected field can be produced every year, and the open field in the north can be cultivated from April to October.

Rhizome propagation from late October to early November, dig up the rhizome from the seed land, select the white, sturdy, short Internode, cut into small segments of 10cm, and then plant into the deep trench of pre-dug 10cm, row spacing 25--30cm, plant spacing 15cm. After planting, cover with fine soil and rake flat and compacted.

Seedling propagation

The fields with sturdy plants, consistent growth and no diseases and insect pests were selected as seed plots. After autumn harvest, immediately ploughing, weeding and topdressing once. In the first ten days of April of the following year, when the seedling was high and 15cm, the seedlings were pulled out and transplanted. Two seedlings were planted in each hole according to row spacing 20cm and plant spacing 15cm. After planting, the soil is compacted, and then poured with thin dung water.

Damage to leaves and stems occurs frequently in rainy seasons. In addition to strengthening the field management and improving the ventilation and light transmission conditions, the prevention and control methods can be sprayed with 25% trimethoprim 1000 Mir 1500 times liquid blade spray.

Spot blight (also known as white star disease)

Damage to the leaves occurred in 5-October. In the early stage of the disease, remove and burn in time or spray with 75% chlorothalonil 500 Mel 700 times liquid.

The main pests are small land tiger and Spodoptera litura. The small land tiger can spray the rhizosphere with 40% chrysanthemum horse EC and chrysanthemum EC 2000Mel 3000 times, or irrigate the roots with 40% methyl isosaliphate 1000 times solution.
