Embodiment 1

[0018] (1) Cut off the stem and drop the head: For jujube trees with high trunk and low yield above 5 years old, the head is directly dropped to about 50cm, so as to promote the germination of hidden buds at the main trunk to make new and strong jujube heads;

[0019] (2) Select and retain high-quality jujube heads: select 3 jujube head branches that are more than 40cm away from the ground, and erase the remaining jujube head branches;

[0020] (3) Pinching of jujube heads and secondary branches: When the jujube heads germinate 4 secondary branches, pluck the top 1cm; after one week of jujube head topping, pick the remaining 4 secondary branches at the fifth node (Take off the top 1-5cm), and at the same time thin out the excess and weak side branches to promote the production of high-quality lignified jujube;

[0021] (4) Jujube tree selection and topping: choose one jujube tree for each side branch, thin out the weak-growing jujube tree, and keep 10 leaf pinches for the shed...

Embodiment 2

[0026] (1) Cut off the stem and drop the head: For jujube trees with high trunk and low yield over 5 years old, the head is directly dropped to 60cm, to promote the germination of hidden buds at the main trunk to make new and strong jujube heads;

[0027] (2) Select and retain high-quality jujube heads: select 5 jujube head branches that are more than 40cm away from the ground, and erase the remaining jujube head branches;

[0028] (3) Pinching of jujube heads and secondary branches: When the jujube heads germinate 6 secondary branches, pick the heart, that is, remove the top 1-5cm; Pick the heart at the top (remove the top 1-5cm), and at the same time thin out the redundant and weak side branches to promote the production of high-quality lignified jujube;

[0029] (4) Jujube hanging selection and topping: choose 2 jujube hanging leaves for each side branch, thin out the weak growing jujube hanging leaves, and keep 10 leaves of the jujube hanging leaves for topping, and the sp...

Abstract

The invention discloses a yield increasing method for low-stem and short-crown red dates, and relates to the technical field of agricultural planting. The method comprises the following steps: cuttingstems to obtain vegetative shoots, selecting and remaining high-quality vegetative shoots, decoring the vegetative shoots and secondary branches, selecting and remaining fruit shoots, decoring the fruit shoots, fixing fruits, harvesting fruits and trimming the shoots in winter. The method disclosed by the invention has the advantages of low tree crown, easiness in management, large red jujube size, high yield, high quality and high fruit setting rate.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for increasing the yield of jujubes with low stems and short crowns. Background technique [0002] Jujube belongs to the plants of Angiosperm, Dicotyledoneae, Rhamnaceae, Rhamnaceae or Jujube. Its vitamin content is very high. Meiyu, which has natural vitamin pills, has the effect of nourishing yin and nourishing blood; Crops with strong adaptability and a wide range of planting, jujube is known as a hardcore crop, with the characteristics of cold resistance and waterlogging resistance, and is the first choice for the development of water-saving forestry and fruit industry. [0003] In recent years, jujube planting in my country has shown rapid growth. The yield and income of jujube trees have increased steadily, and the jujube industry has flourished. Especially for the demand for increasing production of low-stem and short-crown jujubes, a planting method...
