Problems solved by technology

Therefore, this method has to pay a certain amount of production cost (some of the flourishing fruit set is not good, resulting in a decrease in production and quality), and most producers are unwilling to adopt it.

Embodiment 1

[0038] Under greenhouse cultivation conditions, the method for promoting the early cultivation of the giant rose grape of the present embodiment and improving the fruit setting rate comprises the following steps:

[0039] (1) Reasonable control of fertilizer and water before flowering: mainly to control nitrogen fertilizer and less watering to control growth. Under normal circumstances, it is forbidden to apply nitrogen fertilizers such as urea, diammonium, etc. before and after germination (if the growth is weak, apply a little water). Water after topdressing nitrogen fertilizer.

[0040] (2) 7 days before the first flowering, carry out topping of the main shoot, treatment of the auxiliary shoot and the whole inflorescence:

[0041] The method of pinching the main shoot and dealing with the auxiliary shoot is to keep 5-7 leaves above the inflorescence and pick off the top part of the new shoot, erase the auxiliary shoot below the inflorescence, and leave 1 leaf for pinching ...

Embodiment 2

[0045] Under greenhouse cultivation conditions, the method for promoting the early cultivation of the giant rose grape of the present embodiment and improving the fruit setting rate comprises the following steps:

[0046] (1) Reasonable control of fertilizer and water before flowering: mainly to control nitrogen fertilizer and less watering to control growth. Under normal circumstances, it is forbidden to apply nitrogen fertilizers such as urea and diammonium before and after germination of giant rose grapes. If the growth is weak, the amount should not exceed 5kg per mu. Only water once before flowering to keep the soil humidity at 75%-83 %, water after topdressing nitrogen fertilizer after fruit setting.

[0047] (2) 7 days before the first flowering, carry out topping of the main shoot, treatment of the auxiliary shoot and the whole inflorescence:

[0048] The method of topping the main shoot and dealing with the auxiliary shoots is: remove the top part from the 5-7 leaves...

Embodiment 3

[0052] Under greenhouse cultivation conditions, the method for promoting the early cultivation of the giant rose grape of the present embodiment and improving the fruit setting rate comprises the following steps:

[0053] (1) Reasonable control of fertilizer and water before flowering: mainly to control nitrogen fertilizer and less watering to control growth. Under normal circumstances, it is forbidden to apply nitrogen fertilizers such as urea, diammonium, etc. before and after germination (if the growth is weak, apply a little water). Water after topdressing nitrogen fertilizer.

[0054] (2) 8 days before the first flowering, carry out topping of the main shoot, processing of the auxiliary shoot and the whole inflorescence:

[0055] The method of topping the main shoot and dealing with the auxiliary shoots is: remove the top part of the new shoot at 7-9 leaves (retain 4-5 leaves on the inflorescence), wipe off the auxiliary shoots below the inflorescence, leave 1 leaf for p...

Abstract

The invention discloses a method for promoting early cultivation and improving the fertile fruit rate of giant rose grapes. The method comprises the following steps: (1) during the period from sprouting to blossoming of the giant rose grapes, nitrogenous fertilizer is not applied and the soil humidity is 75-83%; (2) in the 7-10 days before first blossoming, pinching of main shoots is carried out, sub-shoots are processed and then inflorescence is managed; (3) in the 3-5 days before first blossoming, new shoots of vain growth are wrenched to enable the vertical new shoots of vain growth to maintain the horizontal state and the parallel new shoots of vain growth to grow downwards in an inclined mode, and the giant rose grapes are cultivated in the environment of greenhouse heat preservation. In the step (3), the new shoots of vain growth are more than 60cm in length, and wrenching of the shoots is carried out on the positions 2-3 joints below the inflorescence. According to method for promoting early cultivation and improving the fertile fruit rate of the giant rose grapes, the fertile fruit rate can be 30-40%, the production requirement can be met, and the rose grapes are full and sweet and can reach the standard of first-class products.

Description

technical field [0001] The invention relates to a method for increasing the fruit setting rate of giant rose grapes under the condition of keeping warm in greenhouses and promoting early cultivation. Background technique [0002] Giant rose grape is a hybrid of Europe and America, originating in China, bred by Dalian Academy of Agricultural Sciences, parent is Shenyang Rose × Jufeng, introduced to Shanghai by Shanghai Malu Grape Research Institute in the spring of 2002. Since 2003, it has been popular in the market because of its excellent quality. Since 2004, it has developed rapidly in the suburbs of Shanghai and has officially become one of the four main grape varieties in Shanghai's grape planting industry. [0003] The giant rose grape has bright purple fruit, high sugar content (soluble solids can reach more than 20% after fully ripening), and strong rose fragrance, so it is very popular in the market. However, this variety grows vigorously, especially under the condi...
