Problems solved by technology

; and in winter with low temperature and little sunshine, due to the small angle of sunlight and weak sunlight, if the north-south ridge cultivation mode is adopted, the plants in the north will be blocked by the plants in the south, and the sunlight received by the plants in the north is seriously insufficient, and the length of the north-south ridge surface in some areas Shorter, only about 10 meters, frequent U-turns are required during mechanical operations, a large amount of labor is required, and the production cost is relatively high

Embodiment 1

[0048] Variety selection: Due to the climate characteristics of low temperature and low sunshine in the winter and spring festivals in Jiangsu Province, we choose cucumber varieties with strong disease resistance, low temperature and high humidity, low light tolerance, moderate plant age, good fruit type and high yield. The variety is Dongmei 906;

[0049] Grafting and raising seedlings: Cucumber grafting and raising seedlings are generally carried out in the solar greenhouse. The grafting and raising seedlings are carried out in mid-to-early October in the autumn. The grafting method is mainly grafting. The rootstocks generally choose pumpkin varieties with developed root systems, strong combining ability and strong disease resistance. Grafting standards The thickness of the hypocotyls of cucumber seedlings and pumpkin seedlings is basically the same, which can increase the survival rate of grafting; grafting seedlings can prevent and control cucumber soil-borne diseases, such as...

Embodiment 2

[0059] The interval between the two ridges on the south side in Example 1 is greater than the interval between the two adjacent north ridges, and the interval between the two ridges on the south side and the interval between the two adjacent north ridges are different by 10-20 cm.

[0060] Using the above scheme, the cucumber yield is 5620kg / mu.

Embodiment 3

[0062] Such as figure 2 As shown, the height of the cucumber main vines on the north ridge in Example 1 is higher than that of the cucumber main vines on the south ridge, and the height difference of the cucumber main vines between two adjacent ridges is 10-20 cm. The hanging rope is used for hanging the vines. 1 A straight line connected parallel to the top of each row of cucumber main vines and moves up and down parallel as the cucumber main vine 2 grows.

[0063] Using the above scheme, the cucumber yield is 5710kg / mu.

Abstract

The invention provides a cultivation method suitable for solar greenhouse overwintering-crop cucumbers. The cultivation method comprises the following steps: a cucumber variety with high disease resistance, low temperature and high humidity resistance, weak light resistance and high yield is selected; pumpkin seedling hypocotyls are grafted on cucumber seedling hypocotyls by a cuttage grafting method in early to mid October; before ridging, furrow application of farmyard manure and base fertilizer and earthing up are carried out firstly, then, three-nutrient compound fertilizer is broadcast, ridging is performed in the east-west direction, after ridging, drip irrigation tapes are spread and mulching is carried out; adjacent two rows of cucumber seedlings are planted on each ridge surface in a triangular shape; when the cucumber seedlings grow to 20 cm or higher, vines are hung obliquely towards the south to enable main vines of cucumbers to form an included angle of 45-60 degrees withthe ground; hanging ropes used for hanging vines are parallel to the ground and vertically parallelly move along with growth of the main vines of the cucumbers; and a solar greenhouse is adopted to control temperature and humidity, the temperature is kept at 25-30 DEG C in the daytime and 13-15 DEG C at night. The cultivation method is suitable for cucumbers to uniformly receive sunlight under low-temperature and less-sunlight conditions.

Description

Technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a cultivation method suitable for overwintering cucumbers in a solar greenhouse. Background technique [0002] Cucumber (scientific name: Cucumis sativus L.) is an annual trailing or climbing herb of the Cucurbitaceae family, also known as courgette and cucumber. Cucumber is one of the main facility vegetables in my country. It has a delicate taste and rich in vitamins and minerals. Stems are used medicinally to reduce inflammation, expectorant and antispasmodic. In order to meet people's demand for fresh cucumbers in winter, there is an urgent need to study the cultivation techniques of overwintering cucumbers in solar greenhouses. For many years, cucumber production has been using the traditional north-south ridge cultivation model. ; And in winter with low temperature and low sunshine, because the angle of sunlight is small and the light is weak, if the north-so...
