Method for preventing and removing field weeds in Paeonia suffruticosa Andr planting with covered with gardening ground film

Abstract

The invention discloses a method for preventing and removing field weeds in Paeonia suffruticosa Andr planting with covered with a gardening ground film. The method comprises the following steps: (1) pre-weeding: for fields with excessive weeds, removing the weeds thoroughly before maturity of grass seeds at the alternated aestivo-autumnal interval; (2) deeply ploughing, tedding and applying base fertilizers: deeply ploughing and tedding the fields one month ahead of planting, and plowing the fields before applying the base fertilizer; (3) finishing the fields and bedding: finishing the fields again before sowing, performing shallow plowing, fine finishing, and bedding; (4) planting: planting the Paeonia suffruticosa Andr in southern China in late October to mid-November, shearing off disease and defective roots and roots which are broken or broken by more than 20cm before planting, then bundling, sterilizing, taking out, draining off and planting; and (5) covering the gardening ground film: covering the gardening ground film along the lines of planted Paeonia suffruticosa Andr, connecting the gardening ground film by ribbons or iron wires closely, and nailing the gardening ground film with gardening ground nail at an internal of 1m. For the method, the air permeability is good, adverse effects on the root systems are avoided and almost no influence on soil physical and chemical properties exists.

Description

technical field [0001] The invention relates to a method for preventing and removing oil peony field weeds by covering planting with horticultural ground cloth, and belongs to the technical field of agricultural production. Background technique [0002] In 2011, the Ministry of Health issued the "Announcement on Approving Ingot Maple Seed Oil and Peony Seed Oil as New Resource Foods". Since then, peony for oil has attracted wide attention as a new type of woody oil crop. By 2016, the national oil peony planting area has exceeded 2.0×10 4 hm 2 , the annual output of peony seeds is nearly 6,000×10 4 kg. At the same time, the annual processing capacity of peony seed oil has exceeded 15,000×10 4 kg. [0003] With the rapid development of oil peony, the management cost is increasing year by year. Especially in the Yangtze River Delta region, weed control is the largest cost expenditure. According to the survey, the current cost of weeding in the Changshanjiao area is 600-12...

AI Technical Summary

Problems solved by technology

[0004] At present, the seeds of peony for oil—peony seeds are cultivated for oil. There are a lot of weeds in the field, and the workload of manual weeding is huge. At present, there is no targeted herbicide. Even if there is, it cannot be used.

Some relevant experts use two-color mulch to lay, which has a certain effect on weed control, but it has a great impact on the root respiration of peony, especially in high temperature and high humidity conditions in summer, peony will die
