Embodiment 1

[0025] A method for splitting roots to prevent water movement in alternate irrigation of peanut root system partitions, characterized in that it comprises the following steps:

[0026] (1) Tilt the cultivation pot with an inclination angle of 45 degrees, fill half of the soil into the cultivation pot, compact it, and level the side of the soil, and the side of the soil is perpendicular to the bottom of the cultivation pot;

[0027] (2) Apply solid Vaseline on half of the soil surface. The thickness of the Vaseline application is 0.5cm. The distance from the highest point of the application position to the opening of the cultivation pot is 5cm. Fill the other half of the soil and compact it to ensure that the soil on both sides of the Vaseline consistent weight;

[0028] (3) Lay the cultivation pot flat, cover the soil surface of the vaseline partition, and sow peanut seeds on both sides above the vaseline, avoid sowing directly above the vaseline to affect seed germination, an...

Embodiment 2

[0031] A method for splitting roots to prevent water movement in alternate irrigation of peanut root system partitions, characterized in that it comprises the following steps:

[0032] (1) Tilt the cultivation pot with an inclination angle of 45 degrees, fill half of the soil into the cultivation pot, compact it, and level the side of the soil, and the side of the soil is perpendicular to the bottom of the cultivation pot;

[0033] (2) Apply solid Vaseline on half of the soil surface. The thickness of the Vaseline is 1cm. The distance from the highest point of the application position to the opening of the cultivation pot is 8cm. Fill the other half of the soil and compact it to ensure the weight of the soil on both sides of the Vaseline. consistent;

[0034] (3) Lay the cultivation pot flat, and cover the soil surface of the Vaseline partition with a thickness of 1cm. When sowing peanut seeds, they should be sown on both sides above the Vaseline to avoid affecting seed germin...

Embodiment 3

[0036] Table 2: Effects of alternate irrigation (PRD) with vaseline and partitions on the growth of potted peanuts at seedling stage

[0037]

[0038] Alternative root zone irrigation technology can promote the growth of plants, but if the test program is not used properly, it may have the opposite effect on the test results. Table 2 lists the effects of vaseline instead of partitions on peanut seedling plants. The effect of alternate irrigation on the root system and root system of peanut seedlings with partitions exceeds 20%, and the water seepage rate in the root zone is 8.76%, indicating that the partitions have affected the peanut seedlings. The effect of alternate irrigation of root partitions; and the alternate irrigation of root partitions using vaseline instead of partitions can promote its growth and development, indicating that the effect of using petroleum jelly on alternate irrigation of root partitions can be ignored.

Abstract

The invention belongs to the technical field of crop cultivation and relates to a root splitting method for preventing water from moving in alternate irrigation of peanut root system zones. The method comprises steps as follows: (1) a cultivation pot is inclined, a half side in the cultivation pot is filled with soil, the soil is compacted, and the side surface of the soil is leveled and is perpendicular to the bottom of the cultivation pot; (2) the surface of the soil on the half side is smeared with solid vaseline, the other half side of the cultivation pot is filled with soil, the soil is compacted, and the weight of soil on two sides of vaseline is consistent; (3) the cultivation pot is placed flatly, the soil surface zoned by the vaseline is covered with soil, and peanut seeds are sown and covered with surface soil again. The method has the advantages that the method is simple, the used material, namely, vaseline, is low in cost, partition boards with special specifications are not required to be manufactured independently, and all that is required is to smear vaseline to the interfaces of the zones of the root systems; by means of characteristics of vaseline, water moving between root zones can be effectively hindered, growth of the root systems is not affected, the root systems can penetrate through the vaseline layer to grow, and the problem of hindering of the partition boards to root system growth is solved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a root division method for preventing water movement in alternate irrigation of peanut root systems. Background technique [0002] Drought and lack of water resources have seriously restricted the sustainable development of food production and agriculture in northern my country. The traditional extensive irrigation technology has led to an extremely low utilization rate of agricultural water, only 30-40%, resulting in a serious waste of water resources. In addition, the rainfall in the northern region is low and the distribution of precipitation is uneven. Every year, grain loss due to drought accounts for 1 / 6 of the total annual output. Therefore, to study the drought-resistant physiology of crops while taking water-saving agricultural measures is one of the important research topics for the sustainable development of agriculture today. [0003] Peanut is a...
