What are the conservation and management measures for weeds?

Weeds are drought-resistant and cold-resistant, grow vigorously, and can be managed extensively after planting. The main maintenance management measure is pruning. Pruning is usually done 4-5 times a year, and the time of 1 is in the middle and late May, which should not be too early, otherwise the growth potential will be weak after pruning, and the last time of 1 is not later than the end of August. The height of each cut depends on the specific situation of each place, generally 3 ~ 5 cm.

Fertilization and watering can increase the density of weeds and prolong the green period to some extent. Fertilization is generally in May and September 1 time, with urea 15 ~ 20g per square meter and sufficient watering.

Weeds grow rapidly, have strong reproductive ability and strong competitive ability with weeds, and there are not many weeds in general. If necessary, the mixture of simazine and 2- methyl -4- chlorine can be used for control in April, which can effectively inhibit the germination of weed seeds and kill the growing dicotyledonous weeds.
