Problems solved by technology

Film mulching can significantly reduce soil evaporation and reduce water consumption by increasing the temperature in the early stage of grape growth. However, due to the rapid long-term temperature increase, it exceeds the optimum temperature for normal plant growth, which is not conducive to plant growth and increased crop yield.

Embodiment 1

[0015] Example 1: See figure 1 , a delayed cultivation method of grapes, the steps of which are;

[0016] (1) In the solar greenhouse, a single-wall fence is used for cultivation, capitulum pruning, mixed pruning of medium and short shoots, the spacing between plants is 0.8m, and the spacing between rows is 2m; the building area of ​​a single shed is 8m×80m,

[0017] (2) Choose a colorless transparent polyethylene plastic film with a thickness of 0.0004mm, and cover it with a width of 80cm between rows; use semi-decomposed wheat straw with a length of 3cm for the covering thickness of 5cm; first cover the straw and then cover it with plastic film. All coverings are spread between the rows of grape plants with a width of 80cm;

[0018] (3) Irrigation: Moderate water deficit means that the soil moisture content is lower than 60% of the field water holding rate for irrigation. After irrigation, the soil moisture content is 70% of the field water holding rate, and the irrigation ...

Embodiment 2

[0021] Example 2: see figure 1 , a delayed cultivation method of grapes, the steps of which are;

[0022] (1) In the solar greenhouse, a single-wall fence is used for cultivation, capitulum pruning, mixed pruning of medium and short shoots, the spacing between plants is 0.9m, and the spacing between rows is 2.25m; the building area of ​​a single shed is 8m×80m,

[0023] (2) Choose a colorless transparent polyethylene plastic film with a thickness of 0.005mm, and cover it with a width of 90cm between rows; use half-decomposed wheat straw with a length of 4cm for the covering of straw, and cover it with a thickness of 8cm; first cover the straw and then cover it with plastic film. All coverings are spread between the rows of grape plants with a width of 80cm;

[0024] (3) Irrigation: Moderate water deficit means that the soil moisture content is lower than 65% of the field water holding rate for irrigation. After irrigation, the soil moisture content is 75% of the field water h...

Embodiment 3

[0027] Embodiment 3: see figure 1 , a delayed cultivation method of grapes, the steps of which are;

[0028] (1) In the solar greenhouse, a single-wall fence is used for cultivation, capitulum pruning, mixed pruning of medium and short shoots, the spacing between plants is 1m, and the spacing between rows is 2.5m; the building area of ​​a single shed is 8m×80m,

[0029] (2) Choose a colorless transparent polyethylene plastic film with a thickness of 0.01mm, and cover it with a width of 100cm between rows; use half-decomposed wheat straw with a length of 5cm for the straw covering, and cover it with a thickness of 10cm; first cover the straw and then cover it with plastic film, All coverings are spread between the rows of grape plants with a width of 80cm;

[0030] (3) Irrigation: Moderate water deficit means that the soil moisture content is lower than 65% of the field water holding rate for irrigation. After irrigation, the soil moisture content is 75% of the field water hol...

Abstract

The invention relates to a straw mulching method which can improve yield and quality of retarding cultured grape trees by improving facilites, in particular to a retarding culture method of grape trees. The retarding culture method of grape trees is mainly characterized by including the following steps: (1) adopting vertical trellis culture in a solar greenhouse, conducting capitate pruning and medium-short mixed trimming, wherein the strain distance is 0.8-1m and the row distance is 2-2.5m; selecting colorless and transparent polyethylene plastic films as thick as 0.004-0.01mm and paving them with the row width as 80-100cm; using semi-decomposed wheat straws with 3-5cm length for straw coverage, wherein the coverage width is 5-10cm; paving the straws before covering mulching films, wherein all coverage substances are paved between rows of grape plants and the paving width is 80-100cm; (3) irrigation: moderately depleting water to irrigate when the soil moisture content is lower than 65% of the field moisture content, wherein the soil moisture content after irrigation is 75% of the field moisture content and the irrigating water quota is 270 m3 / hm2; (4) fertilizing: fertilizing 45-60 m3 / hm2 farm manures and 1500-1800 kg / hm2 calcium magnesium phosphate after fruits of the year before are picked up, fertilizing 500-550 kg / hm2 urea and fertilizing 1225-1500 kg / hm2 in the germination stage, dressing 750-800 kg / hm2 urea in the fruit swelling period, and mounting a fertilizing tank in the greenhouse for fertilizing.

Description

technical field [0001] The invention relates to a cultivation method for improving the yield and quality of delayed cultivation grapes. Background technique [0002] Surface covering cultivation is a technical measure with the main purpose of soil conservation, water conservation and yield increase. It is an advanced cultivation technology popularized and adopted in agriculture at home and abroad in recent years. Different mulching modes can reduce water consumption of crops. Covering can avoid the direct exchange of soil moisture with the external environment, prevent soil moisture from evaporating to the outside and cause water loss, and can conserve soil moisture to varying degrees and reduce evaporation. Film mulching can significantly reduce soil evaporation and water consumption by increasing the temperature in the early stage of grape growth. However, due to the rapid long-term temperature increase, it exceeds the optimum temperature for normal plant growth, which is ...
