Problems solved by technology

Although root-restricted cultivation has many advantages, the root-restricted method and the choice of root-restricted materials are the key factors for the success or failure of root-restricted cultivation.
In the actual application process, the root system at the bottom of the root-restricting container is easy to grow out of the container, and the root-restricting effect cannot be achieved; if the bottom is covered with plastic film, it is easy to cause salt return, which is not conducive to growth

Embodiment 1

[0044] Embodiment 1: Nitrogen management method for reducing walnut empty shell rate

[0045] The present embodiment provides a nitrogen management method for reducing the empty shell rate of walnuts, and the specific steps are as follows:

[0046] (1) Design and manufacture root limiting device.

[0047] (2) Select the test site and measure the soil texture of the test site.

[0048] (3) Fertilizer preparation: Fertilizers at the germination stage include 39.5kg of decomposed sheep manure, 19.5kg of oil residue, 39.5kg of soil, 700g of slow-release nitrogen fertilizer with a release period of more than 90 days, 350g of diammonium phosphate, 350g of potassium sulfate and 100g of compound amino acids, Mix well to obtain.

[0049] The fertilizer for the walnut fruit expansion stage includes 3.8kg of instant nitrogen fertilizer urea, 400g of compound amino acid, and 95.8kg of water, which are obtained after fully dissolving the instant nitrogen fertilizer urea and compound amin...

[0055] Example 2: A Root Restriction Device Applicable to the Nitrogen Management Method for Reducing the Empty Shell Rate of Walnuts

[0056] Refer to the attached Figure 1-7 As shown, the present invention provides a root limiting device suitable for embodiment 1 to provide a method for reducing the empty shell rate of walnut nitrogen, comprising a circular container, the circular container is provided with a base 1, and the base 1 and the circular container are movable Connection, the circular container is formed by connecting a plurality of arc-shaped shrouds 2, and a plurality of round holes 3 are provided on the shroud 2, and a shroud groove 14 is provided at one end of the shroud 2, and a shroud is provided at the other end Convex plate 15, coaming plate groove 14 and coaming plate convex plate 15 are adapted to be arranged, and coaming plate 2 lower end is provided with draw-in groove post 7, and base 1 circumference is provided with a plurality of grooves 11, and gro...

Embodiment 3

[0062] Example 3: Root-limiting device suitable for reducing walnut empty shell rate nitrogen operation method

[0063] Refer to the attached Figure 1-7 Shown, when applying a kind of root-limiting device that reduces the walnut empty shell rate provided by the present invention, earlier open the circular pit of suitable size between the walnut tree plant, earlier the coaming plate projection 15 of coaming plate 2 and coaming plate Groove 14 is connected into a circular container with small hole post 6 through small hole one 4 and small hole two 5, the quantity of coaming plate 2 can be selected according to the size of demand, then base 1 is connected with expansion circle 9, and expansion circle 9 is about to be connected. The groove column 10 on the top is snapped into the groove 11 to achieve the connection between the expansion ring 9 and the base 1, and the connection between the expansion ring 9 and the expansion ring 9. At this time, the number of expansion rings 9 is...

Abstract

The invention discloses a nitrogen operation method for reducing empty shell rate of walnuts. Nutritional characteristics and soil characteristics of walnut trees in main production areas of Xinjiangwalnuts are investigated, a nitrogen fertilizer operation method test is performed according to nutritional requirements of the Xinjiang walnut trees, root limiting device nitrogen fertilizers in different growth periods of the walnuts are prepared, root limiting devices are used for fertilization, the empty shell rate, yield, quality and the like of the walnuts are investigated, and the walnut tree root limiting devices are used for supplementing mineral elements to the walnuts, in this way, the empty shell rate of the walnuts can be remarkably reduced, the per unit yield of the walnuts is increased; and meanwhile, through annual nitrogen fertilizer operation on the walnuts, the phenomena of walnut kernel leakage and shell collapse caused by multi-frequency and high-quantity nitrogen fertilizer input for guaranteeing the walnut yield in the past can be improved. The method is applied to the walnuts of different varieties in different regions. According to the technical scheme, the method is applied to three kinds of walnuts, the yield per mu is increased by 20%-30%, the cost is reduced by 3%-7%, and therefore the method has important significance for management of walnut orchardsmainly based on sandy nature.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a nitrogen operation method for reducing the empty shell rate of walnuts and an application thereof. Background technique [0002] Walnut (Juglans regia) is a plant of the Juglandaceae Juglans genus, also known as Qiang peach and walnut. It can not only be eaten raw, but also can be squeezed for oil and made into cakes. It is not only delicious, but also has high nutritional value. It is often called "longevity fruit" and "longevity fruit". Xinjiang walnuts are well-known at home and abroad for their large size, thin shell, early fruit, high quality and high yield. At the same time, Xinjiang is also the main birthplace of my country's walnut industry. Xinjiang has a long history of growing walnuts, and the walnuts grown in Xinjiang are in Kashgar, Aksu, Hotan and other places in southern Xinjiang. [0003] In walnut production, some fruits do not have seed kerne...
