Embodiment 1

[0023] Embodiment one: to the thinning and pruning of Zheshuang 72 rapeseed

[0024] 1. General situation The planting area is 0.3 mu, and 2400 plants were used for experiments, and the planting date was November 3, 2005.

[0025] 2. Pruning was carried out on March 20, 2006, and the inflorescence was cut for the first time, and the length of the tip was cut off by about 1 cm; the second cutting was on March 30, and the method was the same as the first time.

[0026] 3. Cultivation and management are the same as ordinary rapeseed cultivation.

[0027] 4. Harvested on May 21, 2006. After treatment and drying, the yield of rapeseed was 61 kg, which was 14.2% higher than that of the control.

Embodiment 2

[0028] Embodiment two: To high-oil 605 rape thinning and pruning

[0029] 1. General situation 100 plants were planted for experiments, and the planting time was November 3, 2005.

[0030] 2. Pruning On March 12, 2006, the rapeseed inflorescence was topped for the first time, and the length of the tip was removed by 1 to 2 cm. The second time on March 20th, the method is the same as the first time.

[0031] 3. Cultivation and management are the same as conventional rapeseed cultivation.

[0032] 4. Harvested on May 15, 2006. The average plant yields 68.5 grams of rapeseed, which is 21.5% higher than that of the control.

Abstract

The invention provides a crop pruning method, in particular to a pruning method which can improve the yield per unit area of the rape vegetable flower. The method of the invention is that in March to April, when the florescence of the rape is just over, the young (silique) fruit on the lower end of the anthotaxy comes into being preliminarily, and half of the flowers on the upside of the anthotaxy still do not fade, the technology measurement of pruning (or extirpating) the tip end of the anthotaxy can be conducted to prevent the anthotaxy of the rape from keeping on growing higher and consuming the moisture nourishment, and promote the footstalk on the lower end of the cutting opening to grow thicker, as well as the silique bigger and the purpose of production increase can be achieved with obvious economic benefit.

Description

technical field [0001] The invention relates to a crop pruning method, in particular to a rapeseed (Brassica napus L.) flower-thinning pruning method for improving yield per unit area. Background technique [0002] Pruning is widely used in the production of fruit trees, usually in the planting and juvenile stages, the dry shaping is carried out, and the plants are pruned into a certain shape. Such as the natural happy shape of a peach tree, the evacuated layered shape of a pear tree, etc. At the same time, diseased and insect branches, leggy branches, etc. need to be cut off. The central link is to make the canopy receive sufficient light, the fruit grows robustly, and achieves the purpose of high yield. [0003] The pruning technique is also applied to economic forests such as tea and Kudingcha. [0004] Sesame and soybean topping is to remove the tip of the trunk or branch. [0005] Picking the main moss of rapeseed is also a form of pruning. Rapeseed moss can be eat...
