example 1

[0013] Example 1: The winter wheat variety Shimai 18 was selected. On December 1, bamboo splits with a length of 1m were used to build an arched scaffold with a height of 20cm and a total width of 5m. On January 20th, a plastic film with a thickness of 0.06mm, 0.03mm and 0.03mm from top to bottom and a width of 6 meters was covered on the arch shed. There were holes with a diameter of 20mm on the innermost layer of the plastic film, accounting for about 40% of the total area. . The plastic film around the shed is compacted on the ground with soil. On February 15th, the outermost plastic film with a thickness of 0.06mm was peeled off, and on March 5th, the second layer of plastic film with a thickness of 0.03mm was peeled off. The east and west sides of the three-layer perforated membrane are ventilated. On March 31, the third layer of porous film was removed, and the scaffolding was dismantled at the same time.

[0015] Example 2: The winter wheat variety Hengguan 35 was selected. On December 1, bamboo splits with a length of 1.5m were used to build an arched scaffold with a height of 25cm and a total width of 7m. On January 25th, a plastic film with a thickness of 0.08mm, 0.03mm and 0.03mm from top to bottom and a width of 8 meters was covered on the arch shed. The innermost plastic film had a hole with a diameter of 15mm, accounting for about 35% of the total area. . The plastic film around the shed is compacted on the ground with soil. On February 20, the outermost layer of plastic film with a thickness of 0.08mm was removed. On March 8, the second layer of plastic film with a thickness of 0.03mm was removed. The east and west sides of the three-layer perforated membrane are ventilated. On April 3, the third layer of porous film was removed, and the scaffolding was dismantled at the same time.

[0017] Example 3: The winter wheat variety Heng 4399 was selected. On December 1, bamboo splits with a length of 1.8m were used to build an arched scaffold with a height of 20cm and a total width of 5m. On January 30th, a plastic film with a thickness of 0.08mm, 0.03mm and 0.03mm from top to bottom and a width of 6 meters was covered on the arch shed. There were holes with a diameter of 20mm on the innermost plastic film, accounting for about 40% of the total area. . The plastic film around the shed is firmly on the ground with bricks. On February 18, the outermost layer of plastic film with a thickness of 0.08mm was removed, and on March 10, the second layer of plastic film was removed. The east and west sides of the three-layer perforated membrane are ventilated. Remove the third layer of perforated film on April 1, and dismantle the scaffolding at the same time.

Abstract

The invention discloses a high-yield cultivation method improving grain number per spike and grain weight of winter wheat and advancing maturity. The method is especially suitable for winter wheat ultra-high yield cultivation in wheat and corn double cropping heat shortage regions. Main steps and principles comprise: (1) building a shed frame with height of 20-25 cm, after vernalization of the winter wheat, in the late ten days of January, covering three layers of plastic films on a rye, increasing temperature to promote the winter wheat to turn green early; (2) after temperature rises, keeping temperature under the film stable through reducing the number of film layers, in mid-and-late March, uncovering shed walls on two opposite sides to ventilate, training cold resistance for 5-7 days;(5) in the end of March and beginning of April, when wheat in the shed joints, uncovering a third layer of pore film. Through covering the plastic film, time from turn green to jointing is prolonged,so spikelet number is increased. After the film is uncovered, temperature is relatively low, after wheat jointing, growth becomes slow, floweret deterioration number is reduced, flowering is brought forward, setting percentage is improved, grouting time is prolonged, and wheat matures in advance, and dry hot wind is avoided and grain weight is improved.

Description

technical field [0001] The invention relates to a new crop planting method, which is especially suitable for super-high-yield cultivation of winter wheat under the condition of two-cropping winter wheat-summer corn in the northern part of the North China Plain and the accumulated temperature is extremely tense, and can also be applied to the balance of winter wheat and summer corn crops Increase production. Background technique [0002] (1) Winter wheat-summer corn double-cropping production in the northern North China Plain is seriously insufficient. Winter wheat-summer corn double-cropping is the main cropping system for agricultural production in the North China Plain. The heat resources in the North China Plain decrease from south to north, and the accumulated temperature drops from 5,200°C in Xinyang in southern Henan Province to 4,200°C in Baoding in central Hebei Province. The northern part of the North China Plain is controlled alternately by the winter and summer m...
