Method for promoting growth of cucumbers

Abstract

The invention relates to the field of promotion of plant growth, and discloses a method for promoting growth of cucumbers. The method comprises the following steps: performing sprinkling irrigation treatment on cucumbers once every 7-10 days by using an adjusting agent aqueous solution in the environment with sub-appropriate temperature and light, wherein the sprinkling irrigation treatment is performed for 7-8 times in total, the adjusting agent contains sodium naphthalene acetate and polyaspartic acid in the weight ratio of the sodium naphthalene acetate to the polyaspartic acid being 1:(1-15). According to the method, the plant growth can be promoted, the vitality of root systems is strengthened, the photosynthetic rate is increased, and further the purpose of increasing the yield is achieved. In addition, compared with the prior art, an intelligent sprinkling irrigation device is used for performing sprinkling irrigation on the cucumbers, so that the fertilizer-water proportion can be reasonably controlled, the photosynthetic efficiency can be improved, water resources are sufficiently used, and further the cucumber yield can be notably increased.

Description

Technical field

[0001] The invention belongs to the technical field of promoting the growth of plants, and specifically relates to a method for promoting the growth of cucumbers. Background technique

[0002] Sub-optimal temperature and light environment exist for a long time in solar greenhouses in northern my country, and vegetable growth has been significantly affected. Suboptimal temperature and light can reduce the expression of cucumber N-transport protein gene, thereby reducing the activity of N metabolism-related enzymes and N content, while reducing cucumber photosynthesis, mineral element content and ATPase activity, and inhibiting cucumber growth. At present, the research on alleviating the adverse effects of low temperature and low light is mostly focused on supplementing light and increasing temperature. Although measures such as supplementing light and increasing temperature can alleviate or eliminate the impact of suboptimal temperature and light on plants, they w...

Examples

Embodiment 1

[0088] The tested cucumber (Cucumis sativus L.) variety is "Zhongnong 26", and the tested seedling seedling substrate is a soilless nutrient substrate, which is mainly a mixture of grass charcoal and vermiculite = 2:1 (V / V).

[0089] As the base fertilizer, 20 bags of chicken manure totaling 1000kg, 50kg compound fertilizer and 50kg superphosphate are applied. During the growth and fruiting period, 12 bags of N-P-K (15-15-20) water-soluble fertilizer, totaling 60kg.

[0090] The organic matter content of the nursery substrate is 0.738%, total K is 8900 mg / kg, and total P is 3870 mg / kg. The quick-acting N is 450mg / kg, the quick-acting K is 450mg / kg, and the quick-acting P is 1303mg / kg.

[0091] The content of soil organic matter is 1.06%, total K is 7675 mg / kg, and total P is 1570 mg / kg. The quick-acting N is 620mg / kg, the quick-acting K is 298mg / kg, and the quick-acting P is 129mg / kg.

[0092] The cucumber seedlings are planted when they reach two leaves and one heart. After plantin...

Embodiment 2

[0104] Cucumbers were planted in the same way as in Example 1. When the cucumber seedlings grew to two leaves and one core, the cucumber seedlings were planted. After the planting, the sprinkler irrigation regulator was started; set the 10th group: 2mg·plant -1 Sodium naphthaleneacetate+22mg·strain -1 Polyaspartic acid (a single dosage, the weight ratio of sodium naphthaleneacetate, polyaspartic acid and sodium nitrophenolate is 1:11), wherein the concentration of sodium naphthaleneacetate in the aqueous regulator solution for spray irrigation is 12ppm. The difference from the sixth group in the above-mentioned embodiment 1 is that this embodiment uses the following intelligent sprinkler irrigation device for intelligent sprinkler irrigation of the conditioning agent aqueous solution, such as figure 1 As shown, the smart sprinkler irrigation device includes a water tank 1, a fertilizer tank 2, a soil moisture sensor 8, a signal processing module 9, a control adjustment module 10, ...
