Problems solved by technology

The problems caused by fertilizer damage are: first, the growth of vegetable roots is inhibited, and the function of absorbing water and fertilizer is weakened; second, the concentration of soil solution is too high, and reverse osmosis occurs in vegetable plants, resulting in physiological wilting or leaf margin scorching; The first is to emit toxic gas hazards; the fourth is to cause vegetable deficiency disease
[0004] Second, drug damage
[0006] Four, continuous cropping obstacles

Embodiment 1

[0100] Embodiment 1 tomato

[0101] 1. Greenhouse production in early spring

[0102] (1) Variety: It is advisable to choose varieties with good early maturity, cold resistance, disease resistance, high yield, good commerciality and long shelf life. Shanghai cooperation 903, cooperation 906, cooperation 908 and other tomatoes can be used.

[0103] (2) Land preparation

[0104] Vegetable fertilization should be based on fully decomposed organic fertilizers, with a small amount of chemical fertilizers. Because the mineralization speed of organic fertilizers is slow, it will not cause obvious accumulation of nitrate in plants, and it will help improve the soil aggregate structure and enhance permeability. Apply about 2,500 kg of fully decomposed high-quality organic fertilizer and 40 kg of compound fertilizer per mu of tomato field. If it is continuous stubble, 150-200 kg of quicklime should be applied, which is conducive to adjusting the pH value of the soil and promoting crop...

Embodiment 2

[0142] Embodiment 2 Cucumber

[0143] Cucumber likes warmth and humidity, and is not cold-tolerant. The suitable temperature for growth is 20-30°C, and the growth stagnates below 10°C, and it has a strong tolerance to high temperature. Using greenhouses to cultivate cucumbers can be sown one month earlier than open field cultivation. The yield per mu is 2500-300 kg, and the market is about 20 days earlier. The price is good and the economic benefits are considerable. The main cultivation techniques are as follows:

[0144] 1. Variety selection

[0145] Choose early-maturing, high-yielding, disease-resistant varieties such as Jinyou 1, Jinchun 2, Jinyou 20, and Jinyou 30 that are suitable for greenhouse planting.

[0146] 2. Sowing period

[0147] The best time for sowing is mid-January.

[0148] 3. Sowing seedlings and cultivating strong seedlings

[0149] 1. Seed disinfection, soaking and germination

[0150] Soak the seeds in hot water at 55°C for 10 minutes for high-...

Embodiment 3

[0170] Embodiment 3 bitter gourd

[0171] 1. Greenhouse production in early spring

[0172] (1) Variety: It is advisable to choose varieties with good early maturity and good commerciality. Xueyuzao, Chunhua, Lanshan bitter gourd and other varieties can be used.

[0173] 2. Sowing period

[0174] The best time for sowing is mid-February.

[0175] 3. Cultivate strong seedlings

[0176] 1. Seed soaking and germination

[0177] Soak the seeds in hot water at 55°C for 10 minutes for high-temperature disinfection, continue to soak the seeds for 18-22 hours, then break the shells, soak them in warm water for 2 minutes, pick them up, wrap them in a wet towel and place them at a temperature of about 32°C to accelerate germination , When the germ grows to 0.3-0.5 cm, it can be sown.

[0178] Other reference cucumber

[0179] 4. Colonization

[0180] Planting time: Generally, it can be planted in the middle and late March.

[0181] Planting density: Generally, 1500-2000 plants ...

Abstract

The invention discloses a premature efficient cultivation method of greenhouse vegetables. The method comprises the following steps of step I, constructing a greenhouse; step II, adjusting and controlling environment conditions in the greenhouse; step III, performing anniversary crop rotation arrangement of greenhouse vegetables; step IV, cultivating vegetables in the greenhouse; and step V, controlling diseases and insect pests and physiological barriers. According to the method disclosed by the invention, appropriate vegetable varieties are selected, fertilizer damage, pesticide damage, drought damage and continuous cropping obstruction can be overcome, and the cultivation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for early-maturing and high-efficiency cultivation of greenhouse vegetables. Background technique [0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. It appears that people can eat off-season vegetables. Generally, the vegetable greenhouse uses a bamboo structure or a steel structure frame, covered with one or more layers of thermal insulation plastic film, thus forming a greenhouse space. The outer film can well prevent the loss of carbon dioxide produced by the growth of vegetables inside, so that the shed has a good heat preservation effect. Artificially creating a suitable ecological environment, adjusting vegetable production seasons, regulating market demand, and promoting high-quality and high-yield vegetables are one of the effective means to increase farmers' income. Judging from the sur...
