Problems solved by technology

Returning crop straw to the field is to supplement and balance soil nutrients. The biggest problem with returning straw to the field is that it is difficult to plow the straw into the soil
Even when the straw is successfully plowed into the soil, other problems can arise in the straw in the furrow, such as tearing the mulch, hindering root growth
③ Straw energy, including biomass fuel, straw gasification, processing briquette fuel, making gas, etc. This method is not conducive to the improvement of organic matter in cultivated land soil
④Building materials, light industry and textile raw materials, such as straw boards, are currently processed in a small amount and the utilization rate is not high
⑤ Straw substrate. The use of straw as a base material for edible fungi is a food-related technology. At present, the technology of using straw to produce oyster mushrooms, shiitake mushrooms, enoki mushrooms, and Coprinus comatus is relatively mature, but there are problems with high technical requirements. Corn stalk and wheat stalks have a low yield of edible fungi

Embodiment 1

[0032] A method for fertilizing compressed jujube stalks comprising the following steps:

[0033] The first step is the production of compressed straw fertilizer blocks. The crushed straw (60%), clay (25%), and mineral source fertilizer (15%) are mixed with water and then compressed into blocks using a briquette machine. After air drying, a diameter of 15cm-16cm, cylinder or cuboid with a height of 12-13cm, the finished product is a straw compressed fertilizer block with 3-5 holes in the middle. Mineral source fertilizers include fulvic acid, magnesium stone powder, boron mud, phosphate rock powder, potassium feldspar, etc. Fulvic acid has small molecular weight, high active genes, improves soil, increases ground temperature, promotes root development, and effectively adjusts soil pH, etc. unique effects. In the case of dry climate, it reduces the stomatal opening of crops, commonly known as "Drought No. 1". Mineral source fertilizers such as phosphate rock powder, potassium...

Embodiment 2

[0041] Embodiment 2 Fish scale pit:

[0042] In the method described in embodiment 1, for the jujube orchard on the sloping land of about 15 ° for slope, rainwater collectors can not be used, but fish scale pits are built, and the length and width of the fish scale pits are 1.5m*1m, and the depth of the pit is 50cm. The application point of the straw compressed fertilizer block is at the deepest depth of the fish scale pit.

Embodiment 3

[0043] Example 3 Ridging of tree trays:

[0044] In the method described in embodiment 1, for the jujube orchard on the flat ground, especially the jujube orchard that can utilize external water sources such as dry wells and river water to carry out a small amount of irrigation, it is possible to carry out ridging of the tree tray or ditching under the crown without using a rainwater collector. During the dry season, when the tree tray is used for irrigation or ditch irrigation, the limited water can be introduced into the depth of the soil by using the water guide of the straw compressed fertilizer block to improve the drought resistance of the orchard.

Abstract

The invention discloses a straw compressed block for a dry farming jujube orchard and a fertilizing method thereof. The fertilizing method comprises the following steps: preparing a straw compressed fertilizer block with the central part provided with 3 to 5 hollow holes; preparing a straw rainwater collector; selecting 2 to 4 points below the crown of the peripheral crown of a jujube tree in early October and middle October in autumn or in mid-to-late April in spring every year, and digging pits by using a pit digging device; and placing 2 to 3 straw compressed fertilizer blocks into each pit, mounting rainwater collectors above the straw compressed fertilizer blocks, when topdressing is performed on jujube trees according to the requirements of different phenological periods, dissolvinga formula fertilizer with 20 to 30 kg of water, and guiding the dissolved formula fertilizer into an underground soil layer through channels of the hollow holes arranged at the middle parts of the straw compressed fertilizer blocks. The fertilizing method provided by the invention realizes innovative utilization of straw, and can improve the fertilizer and water utilization rates of arid and semi-arid areas, specifically rain-fed agricultural areas.

Description

technical field [0001] The invention discloses a compressed straw block for dry jujube orchards and a fertilization method thereof, belonging to the technical field of straw treatment and utilization methods. Background technique [0002] The soil barrenness of cultivated land in our country is serious. The low content of organic matter is the main factor restricting the quality of fruits in my country. At the same time, the organic matter of orchard soil has not only reached the lowest point in history, but also close to the ecological "warning line". What is even more worrying is that the organic matter of cultivated land is still declining at an annual rate of 0.05 percentage points. In the development of the fruit tree industry, we should insist on using land to cultivate land and improving soil quality, which is of great significance to improving product quality and realizing supply-side reform. [0003] The red jujube cultivation areas on both sides of the Yellow Riv...
