How to prepare and fertilize autumn cucumbers in the open field?

The stubble of autumn cucumbers in the open field is spring crops, most of which are stubble at the end of June and early July, and the rain is generally sufficient in various places during this period, and the weeds breed seriously. Therefore, after the harvest of the previous crops, it is necessary to remove the dead branches and rotten leaves, especially the weeds, in time to avoid the hidden dangers caused by weeds in the melon field, and then turn the dry soil deeply, and require a certain number of days to expose the soil, increase fertility, kill part of the soil-borne pests and diseases, and at the same time can be appropriately applied to fully rotted and pollution-free manure manure or human manure as base fertilizer, and 3000 4000 kg per 667 meters 2. After ploughing and mixing well and fully exposed to the sun, make furrows.

In autumn, open-field cucumber cultivation is generally made into small high furrows to facilitate growth. Small furrows are generally 1 meter wide (40 50 cm wide furrows, 60 cm wide furrows) planted in two rows, with a plant spacing of 22 cm.

For base fertilizer, you can use well-rotted poultry manure, chicken manure, and cow manure, but it should be rotten, that is, after fermentation, and then with microbial agents, you can choose more strains, such as 2 billion, 6 active bacteria, such a fungus agent has high bacterial activity, especially the fungus agent with Trichoderma harzianum, the activity will be higher, so manure + 2 billion bacteria agent can be used as base fertilizer.

Cucumber is a temperature-loving and humidity-loving plant, with a suitable growth temperature of 18 32, a suitable air relative humidity of 70% 90%, and a soil moisture of 85% 95%.

Cucumber has a shallow root system, so it should be cultivated in humus loam soil rich in organic matter and good air permeability. The soil should be mildly acidic to weakly alkaline. It can be applied with rooting agent and Yanwo biological fungus.

Seedling fertilization: use Yanwo water-soluble fertilizer, fully and evenly. If you find that there is a lack of fertilizer at the seedling stage, you can use Yanwo potassium dihydrogen phosphate foliar fertilizer and spray it on the foliage.

It is conducive to cultivating strong seedlings.

Plantar fertilizer: Generally, the roots enjoy rooting agents and Yanwo biological fungi agents, which are conducive to slowing down seedlings.

Soil top dressing: 5000 kg of cucumber per mu, from planting to the end of harvesting, a total of 8 10 times of top dressing. The first top dressing after planting slow seedlings was mainly water-soluble fertilizer. In the peak period of vegetable melon, increase the number of top dressing. It is conducive to promoting the normal development of fruits and the healthy growth of plants.

Cucumber bottom fertilizer, with rotten sheep manure, it is best to add bacteria twice rotted sheep manure, high organic matter content, less harmful bacteria, do not burn the roots and do not hurt the roots, can effectively improve the yield and quality!

This batch of cucumbers should be cultivated very well, because it is very difficult to feed these cucumbers if they are cultivated after the autumn. So I think we should use good fertilizer to fertilize which Zen.

When watering cucumbers, you should be careful to water once every 4 or 5 days, and you can water once a week after the weather turns cooler.

1. Apply sufficient base fertilizer: the vegetative growth of cucumber before melon formation is the stage to lay the foundation for later flowering and melon, especially the development of root system, which directly affects the absorption of water and fertilizer in the later stage. Therefore, when cucumber is planted, the application of sufficient basal fertilizer and re-application of Luyuanyou's rotted organic fertilizer can fertilize the soil and improve the structure of the cracked soil, which is conducive to the growth of the root system.

The specific amount of fertilizer should be reasonably determined according to the local soil fertility level and the planned yield, generally 400-600 kg of commercial organic fertilizer or 2000-3000 kg of rotting manure, 20-35 kg of phosphorus nitrate fertilizer, and 3-6 kg of potassium sulfate per 667m2. 2. Reasonable topdressing with acacia fertilizer: the topdressing of cucumbers should follow the principle of a small amount of many times, and each topdressing should be combined with irrigation as much as possible to facilitate the dissolution and absorption of nutrients.

At the seedling stage, unless the seedlings are defertilized and grow poorly, they should not be topdressed. The topdressing period should be grasped after the root melon is harvested, and then immediately after each picking, topdressing 1 time or 1 topdressing every 10-15 days.

To choose a fertilizer suitable for cucumbers, we should pay attention to the stage of fertilization, but also pay attention to the control of temperature, according to the growth of cucumbers, choose fertilizers at different stages, and also pay attention to some management skills, etc.

In fact, it is necessary to mix with water for fertilization, do not fertilize when the temperature is too high, you must pay attention to the proportion when fertilizing, can not lead to too high or too low concentration, try to fertilize evenly and evenly spread the fertilizer in each place.

The correct method of cucumber fertilization: bottom fertilizer, cucumber fertilization to eat less and more meals, seedling stage, early flowering stage, cucumber to apply as much organic fertilizer as possible, common organic fertilizer, flower bud differentiation, top dressing, harvest period.

The increase of base fertilizer should be dominated by organic fertilizer, supplemented by organic fertilizer. Generally speaking, for plots with medium soil fertility efficiency, 4000-6000kg of pig manure and 20-30kg of phosphate fertilizer can be increased for 1 mu. Cucumber topdressing organic fertilizer should prevent the amount of one-time use is too high, especially organic fertilizers such as ammonium chloride and sodium chloride are not easy to be high.

Be sure to eat small and frequent meals to prevent the accumulation of salinity in the soil and cause more salt to hinder. Each royal servant grows a variety of chemical fertilizers, and the maximum amount of fertilizer applied at one time should not be too much. One week after transplanting, the water-soluble fertilizer of the long-rooted seedlings was applied when the agricultural mulch film was applied when the seedlings were watered.

Generally, amino acid sedans are used for water-soluble fertilizer, and the amount of fertilizer per mu is about 5 kg.

Pay attention to the closure and merger

The main purpose is to promote the germination of new roots at the seedling stage, the growth and development are robust and abundant, and lay the foundation for the later melon formation. Can be sprayed through the leaves of urea solution, or potassium dihydrogen phosphate solvent. Plant fertilizer needs to be dominated by thin farm fertilizer, and a small amount of frequent meals should be used.

Cucumbers need to apply more well-rotted organic fertilizer, which can not only make the soil loose, warm, breathable, and lock in water and solid soil. It will not affect the growth and development of young stems because of the high concentration of soil solution. Common Organic Fertilizers:

Mule and horse manure, mule and horse trotters, farm manure, chicken and duck manure, etc. Organic fertilizer is best used in greenhouses, containing tanks or ponds.

Hello, August is the autumn cucumber planting season, before planting, we must first understand the cucumber planting technology and management, which choose the planting time, select excellent varieties, reasonable fertilization, scientific management are more important content.

Preparation before planting.

Autumn cucumber planting to choose a good time, generally speaking, cucumber planting time in autumn to choose the beginning of August, this period has passed the summer high temperature and high humidity stage, the temperature has dropped, the precipitation is relatively reduced, pests and diseases are not easy to breed. In addition, the suitable temperature for cucumber flowering and fruiting in autumn is about 30 degrees Celsius, so there are still certain requirements for temperature.

In addition, growers should choose cucumber varieties suitable for their own environment and soil before planting, otherwise there may be low fruit setting rate and many diseases.

Cucumber fertilization is reasonable.

Cucumber is a crop with a relatively short maturity period and rapid growth, so it is necessary to choose a fast-acting fertilizer when using fertilizers, such as water-soluble fertilizers with a large number of elements.

In addition to the traditional manure, you can also use the finished organic fertilizer, compound fertilizer, and add microbial agents to improve the soil and improve the fertilization efficiency, such as the microbial agent of the sea, 6 kinds of salt-tolerant compound bacteria, with a bacterial content of 2 billion grams, which can enhance soil activity and permeability, and the effect is good.

After the cucumber enters the growth period, it is necessary to give an appropriate amount of topdressing according to the growth of cucumber, reasonable topdressing, and the water-soluble fertilizer can be selected when topdressing, and it is applied together with irrigation each time.

Cucumber plantation park management.

Cucumbers have a large demand for water and need to be watered in a timely manner, but it is necessary to pay attention not to over-irrigate, otherwise it will cause diseases and lead to reduced yields, especially in summer, there will be a large amount of precipitation in a short time, and it is necessary to drain water in time to avoid excessive water.

Cucumbers are also prone to pests and diseases, such as aphids, downy mildew, etc., which need to be controlled from the seedling stage, sprayed with pesticides in time, and cleaned up the park.

Do a good job in water and fertilizer management and pest control, the yield of cucumbers can be basically guaranteed, and then according to the growth of the timely erection and harvesting, to avoid high temperature caused by the aging of cucumbers.
