Ecological planting method for interplanting herba capsellae in peach orchard

Abstract

The invention discloses an ecological planting method for interplanting herba capsellae in a peach orchard. The method comprises the following steps: (1) land preparation: selecting a well-drained sandy-loam peach orchard with a peach tree spacing of 5m, excavating dead furrows with the width of 35cm to 40cm and the depth of 40cm to 50cm among the peach trees, and applying 2,000kg / hm<2> of organicfertilizer and 1,000kg / hm<2> of three-element compound fertilizer into the dead furrows; (2) sowing: selecting a small-leaf herba capsellae variety, sequentially excavating six rows in each side of soil between the peach trees and each dead furrow in a manner that each row has a length of 25cm, and sowing 1kg to 1.5kg of seeds per 667m<2> in early march in a manner that full contact between the herba capsellae seeds and the soil is guaranteed; (3) fertilizer and water management: carrying out seedling emergence 5 to 7 days after sowing under normal conditions, and watering a proper volume ofwater after seedling emergence to guarantee soil moist; (4) plant disease, insect pest and weed control: employing pymetrozine and imidacloprid pesticides to control aphids of the herba capsellae; (5)in-time picking: carrying out picking when the number of true leaves is 10 to 13; and (6) reserving seeds in last batch of harvesting of the herba capsellae; dispelling ladybirds, lacewings and minute pirate bugs to the peach trees, so as to control peach aphid pests; and crushing the remaining herba capsellae with a rotary tiller, and then, carrying out deep tillage for direct field returning, so as to improve a soil structure of the peach orchard and increase organic matter supply.

Description

technical field

[0001] The invention relates to the technical field of agricultural ecological planting, in particular to an ecological planting method for interplanting shepherd's purse in a peach orchard. Background technique

[0002] Peach (Amygdalus) originates in China and has a very wide distribution range. At present, the main production areas are Jiangsu, Zhejiang, Shandong, Hebei and other provinces. Peach is a small deciduous tree with high economic value. Peach blossoms can be viewed and admired. The fruit is nutritious and juicy. It can be eaten raw or made into preserved peaches and cans. Peach kernels are also edible. For a long time, the cultivation of peach orchards has been dominated by clear tillage. The ecological diversity in the orchard has decreased sharply. The control effect of natural factors on common peach diseases, insect pests and weeds has declined. The frequency and amount of chemical fertilizers and pesticides used have increased, resulting in...
