Problems solved by technology

[0005] In order to overcome the problems of low yield and poor quality of jujube planting in sandy soil in the prior art, the present invention provides a biological fertilizer method for drip irrigation of sandy soil in jujube orchards. This method can quickly fertilize jujube under the condition of drip irrigation. The sandy soil of the garden improves the yield and quality of red dates; and this method reduces the amount of farm manure and reduces the cost

Embodiment 1

[0018] Choose a conventional red jujube dense planting garden, the age of the tree is more than 2 years but less than 8 years, the tree height is more than 40 cm, the number of jujube trees per mu is 250, and at a distance of 30 cm from the stem of the jujube tree, 2 peanut seeds are ordered every 8 cm , as shown in the attached picture, distributed in a circular shape, with a total of 23 on-demand holes, a total of 5,750 on-demand holes per mu. The jujube trees are irrigated with a single-tree, single-pipe drip irrigation system. In the field, according to the biomass of 200 grams per hole, a total of 1,150 kilograms of root stubble per mu is returned to the field.

Embodiment 2

[0020] Choose a conventional jujube orchard, the age of the tree is more than 2 years but less than 8 years, the tree height is higher than 40 cm, the number of jujube trees per mu is 144, and at a distance of 30 cm from the stem of the jujube tree, 3 peanut seeds are sown every 8 cm. As shown in the attached picture, it is distributed in a circular shape, with a total of 23 holes on demand, and a total of 3321 holes on demand per mu. The irrigation method of jujube trees adopts a single-tree single-pipe drip irrigation system, and dissolves soluble fertilizer urea and high-purity potassium sulfate and injects them into irrigation. The system is combined with irrigation water to achieve the purpose of drip irrigation with fertilizer and water. After the peanut growth period is over, the root stubble and grains are completely returned to the field. According to the biomass of 260 grams per hole, the total root stubble returned per mu is 861.12 kg, of which the peanut Planting fr...

Embodiment 3

[0023] Choose a conventional jujube orchard, the age of the tree is more than 2 years and more than 8 years, the tree height is more than 40 cm, the number of jujube trees per mu is 144, and at a distance of 30 cm from the stem of the jujube tree, 3 peanut seeds are ordered every 10 cm , as shown in the attached picture, distributed in a circular shape, a total of 18 holes were sown on demand, and a total of 2592 holes were sown on demand per mu. The irrigation method of jujube trees adopts a single tree double-pipe drip irrigation system. Field, according to the biomass of 220 grams per hole, a total of 570.24 kg of root stubble per mu.

Abstract

The invention relates to a sand soil improvement technology, in particular to a biological fertilization method for sand soil of a date garden. The method provided by the invention adopts the technical scheme that peanuts are uniformly planted in a position with a distance being 20 to 30cm away from a date tree stem, after the peanut growth period is completed, root stubbles and seed parts of the peanuts are completely returned back into field, and the irrigation mode of the date tree is the drip irrigation mode. Through the technical scheme, the problems of low red date planting yield of sand soil and poor fruit product quality in the prior art are solved, and the drip irrigation biological fertilization method for the sand soil of the date garden is provided. The method has the advantages that under the drip irrigation conditions, the sand soil of the date garden can be fast fertilized, the yield and the quality of the red date are improved, in addition, the consumption of farmyard manure is reduced by the method, and the cost is reduced.

Description

technical field [0001] The invention relates to sandy soil improvement technology, in particular to a biological fertilizer method for sandy soil in jujube orchards. Background technique [0002] Due to the unique ecological environment and climatic conditions in Xinjiang, the red dates planted are smooth and bright in appearance and have high nutritional value. Therefore, the government vigorously promotes the cultivation of jujubes. In 2011, the cultivation area of ​​jujubes in Xinjiang was 48.10×10 4 hm 2 (7.215 million mu), it has leapt to the first place in the area of ​​forest and fruit in Xinjiang. The planting area extends to the edge of typical deserts in Xinjiang, such as Korla, Aksu, Kashgar and Hotan. This area is mainly dominated by large areas of sandy soil. The characteristics of sandy soil are: sand content exceeds 50%, clay If the content is less than 30%, the pores between the soil particles are large, the small pores are few, the capillary action is wea...
