Problems solved by technology

The advantage of flush fertilization is convenient fertilization and labor-saving; the disadvantage is that when the amount of irrigation water is large, the fertilizer is evenly dissolved in the water, and the concentration of fertilizer is low, resulting in low nutrient concentration in the soil solution, which is not conducive to the absorption of vegetable roots ; Only when the amount of fertilizer is large, the concentration of the soil solution can be increased to meet the requirements of vegetable root absorption; some nutrients move directly with the water to the deep soil layer, causing environmental pollution
Therefore, a prominent problem in the fertilization and cultivation technology of solar greenhouse vegetables is that the amount of fertilizer is too large
Excessive fertilization not only increases the production cost of farmers, but also causes environmental problems such as accumulation of soil nutrients, leaching of nitrate, deterioration of product quality and salinization of soil

Embodiment 1

[0011] Take eggplant as an example:

[0012] Soil fertilization, plowing, ridging, and transplanting of eggplants. After the eggplant seedlings are slowed down and before the plastic film is covered, an open hole 2 is dug on the ridge between the two eggplants on both sides of the irrigation ditch 3, and the open hole 2 is close to the irrigation. One side of the ditch 3, and open to the side of the irrigation ditch 3, the bottom of the cave 2 is 5 cm higher than the bottom of the irrigation ditch 3, and the bottom of the cave is lower than the water level of the irrigation ditch 3. There is a through hole corresponding to the mouth of the open hole 2 on the plastic film above; 5g of chemical fertilizer 4 is put into the hole of the open hole 2 one day before watering, and when watering, the water flows into the open hole 2 to dissolve and diffuse the chemical fertilizer; Make holes once and use them throughout the growth period of eggplant.

Embodiment 2

[0014] Take tomato cultivation as an example:

[0015] Soil fertilization, plowing, ridging, and transplanting of tomatoes. After the tomato seedlings are slowed down and before the plastic film is covered, an open hole 2 is dug on the ridge between the two tomatoes on both sides of the irrigation ditch 3, and the open hole 2 is close to the irrigation. One side of the ditch 3, and open to the side of the irrigation ditch 3, the bottom of the open hole 2 is 10cm higher than the bottom of the irrigation ditch 3, and the bottom of the hole is lower than the furrow irrigation water level of the irrigation ditch 3. There is a through hole corresponding to the mouth of the open hole 2 on the plastic film above; 15g of chemical fertilizer 4 is put into the hole of the open hole 2 one day before watering, and when watering, the water flows into the open hole 2 to dissolve and diffuse the chemical fertilizer; Make holes once and use them throughout the growth period of tomatoes.

Embodiment 3

[0017] Take growing peppers as an example:

[0018] Soil fertilization, plowing, ridging, and transplanting of peppers. After the peppers are slowed down, an open hole 2 is dug on the ridge between the two peppers on both sides of the irrigation ditch 3, and the open hole 2 is close to the side of the irrigation ditch 3. , and open to the irrigation ditch 3 sides, the bottom of the hole 2 is higher than the bottom of the irrigation ditch 3 by 7.5cm, and the bottom of the hole is lower than the water level of the irrigation ditch 3. Add 10g of chemical fertilizer 4, and when watering, the water flows into the open hole 2 to dissolve and diffuse the chemical fertilizer; once the hole is made, the whole growth period of pepper is used.

Abstract

The invention relates to a method for fertilizing with open cavity. Wherein, it digs open cavities on the ridges at two sides of vegetables of irrigation groove; the open cavity is at the inner side of irrigation groove while it opens to the groove; the bottom of cavity is higher than the bottom of irrigation groove at 5-10cm, while the bottom is higher than the water level of irrigation; at 1-2 days before irrigation, putting 5-15g fertilizer into cavity; irrigating the flow into cavity, to dissolve and expand fertilizer. The invention can reduce the process to dig cavity and cover soil, to utilize fertilizer fully. The invention can realize integrated fertilization.

Description

technical field [0001] The invention relates to a fertilization method for planting vegetables, in particular to an open hole fertilization method. Background technique [0002] At present, the main cultivation method for vegetable production in solar greenhouses is soil cultivation, furrow or border irrigation is used for irrigation, and flush fertilization is used for topdressing. The advantage of flush fertilization is convenient fertilization and labor-saving; the disadvantage is that when the amount of irrigation water is large, the fertilizer is evenly dissolved in the water, and the concentration of fertilizer is low, resulting in low nutrient concentration in the soil solution, which is not conducive to the absorption of vegetable roots ; Only when the amount of fertilizer is large, the concentration of the soil solution can be increased to meet the requirements of vegetable root absorption; some nutrients move directly with the water to the deep soil, causing enviro...
