Repairing method of soil in kiwi orchards

Abstract

The present invention relates to a repairing method of soil in kiwi orchards. The repairing method of the soil in the kiwi orchards comprises the following specific steps: S1, layered improvement is conducted: a topsoil block diameter is adjusted to be less than 1 cm and a use amount of a farmyard manure is more than 20 tons / mu; a bottom soil block diameter is adjusted to be less than 10 cm and ause amount of the farmyard manure used is more than 10 tons / mu; S2, field ditches are designed: central ditches and ring ditches are dug, soil on both sides of the center ditches is gathered to form ridges to form multiple ridge belts and field ditches, circuits are arranged in the ring ditches, height of the ridge belts is larger than height of the circuits, height of the circuits is the same asheight of the field ditches, height of the circuits is larger than height of the ring ditches, and height of the ring ditches is the same as height of the central ditches; and S3, rehabilitation yearby year is conducted: the farmyard manure is applied, planting by a green manure is conducted, and earthworms are put every year. The repairing method improves yield and quality of kiwifruits.

Description

Technical field [0001] The invention relates to an orchard soil management technology, in particular to a method for repairing kiwi orchard soil. Background technique [0002] Since the National Kiwi Scientific Research Symposium was held in Xinyang, Henan in 1978, the kiwi fruit industry has ushered in a vigorous development in my country for 40 years. As of 2018, the total planting area of ​​kiwifruit in the country has exceeded 240,000 hectares, and the resulting area is about 160,000 hectares, with an annual output of about 2.55 million tons, making it the seventh fruit planted in my country. In the actual production of kiwifruit, since soil restoration was not taken after the establishment of the garden, the kiwifruit tree body may be generally in a sub-healthy state, prone to root rot, canker, etc., ranging from dead trees to damage to the garden; in addition, production Fruits are also prone to quality problems such as poor ready-to-eat, intolerance to storage, and unstab...

AI Technical Summary

Problems solved by technology

In the actual production of kiwifruit, due to the lack of soil restoration after the establishment of the garden, the kiwifruit trees may generally be in a sub-healthy state, easily infected with root rot, canker, etc., ranging from dead trees to serious damage to the garden; Fruits are also prone to quality problems such as poor ready-to-eat properties, intolerance to storage, and unstable flavor and taste, which affect market prices
