How to carry out scientific planting management of greenhouse loofah? What should I pay attention to

Greenhouse loofah should be planted and managed on a daily basis, and attention should be paid to breeding and seedling raising.

The management of greenhouse loofah planting is not achieved overnight, and scientific planting management must run through the entire loofah growth process. First of all, we should pay attention to the issue of breeding and seedling. Because seed selection and seedling raising are the most critical steps in loofah planting, the author will first introduce the relevant aspects:

The so-called breeding is to select high-quality seeds of excellent varieties. The total quality of the loofah can ensure that the loofah will have strong disease and drought resistance and good growth in the future. High quality can ensure a high seed emergence rate, so seed selection is crucial.

After breeding, it is the seedling, the seed should be put in the water to absorb the water, the seed metabolism will be vigorous after washing, so the seed activity is increased, and then the seed is sown into the moist soil and waits for the seedlings to grow, and the seedling is completed.

In addition to the selection and seedling raising of greenhouse loofahs, we should also pay attention to these problems: pay attention to the application of chemical fertilizers in the early stage, pay attention to the appropriate temperature, and pay attention to the prevention of diseases and pests. These points are explained in detail below:

1. Greenhouse loofah planting should pay attention to the early application of chemical fertilizer: because the greenhouse loofah seedlings grow rapidly in the early stage, and the vines can quickly climb up, so nutrition is essential, so chemical fertilizer should be applied in time in the early stage. Because potassium is needed for leaves and vines to grow, potassium fertilizers should be applied more often.

2. Pay attention to the appropriate temperature for greenhouse loofah planting: the greenhouse loofah and its melon vine leaves belong to the broad leaves, and the broad leaves have a characteristic that they are heat-resistant but not cold-resistant, if the temperature is too low, the leaves will fall off, and the whole loofah vine will wither and die. Therefore, in order to avoid this situation, it is necessary to maintain the greenhouse temperature above 20 degrees, and the suitable temperature is about 25 degrees.

3. Greenhouse loofah planting should pay attention to preventing pests and diseases: there is an insect called mole cricket, which likes to eat plant vines, so it is very destructive to loofah. So this insect should be killed.

Because mole crickets hide in the soil, the specific method is to turn the shallow layer of soil to the side first, and then spray pesticides, so that the mole crickets can be effectively poisoned.

I think the first thing to do is to choose excellent varieties, try to choose some varieties with strong growth and strong adaptability; Fertilize the land where the loofah is planted, disinfect the seeds of the loofah, and select some loofah seeds with strong market adaptability; It is necessary to pay attention to the disinfection and sterilization of loofah seeds, and the loofah can be moderately promoted.

Water and fertilizer management can be carried out, and the temperature of the greenhouse should also be managed, so that scientific management can be carried out. It is necessary to pay attention to the temperature of the greenhouse, the humidity, the planting process, the planting spacing, and the way of maintenance.

It is necessary to choose the right variety, be sure to pay attention to the light, pay attention to the surrounding environment, need to treat the soil, pay attention to watering, pay attention to fertilization.

The loofah vine is about 1 meter long, and the vine fertilizer should be applied before the frame is erected. It is best to use rotten human manure and urine, if you only plant three or two, there will be a lot of wood, and chemical fertilizer will be used. We use 10 20 catties of compound fertilizer for one acre of land here, or flush with water or ditch application.

The physiological characteristics of the loofah are very fertilizer-loving, sunny, and the climate with obvious temperature difference between day and night, and should be applied to the planting plot with an appropriate amount of organic fertilizer and the soil is evenly turned over and then dried for 1 2 days to sow seeds, increase soil permeability and play a role in sterilization and disinfection, and the appropriate temperature for seed germination is about 28, and the germination will be relatively rapid when it is 30-35, and the growth is slow when it is below 18, so if the loofah is to be planted in the open field, it is best to choose when the temperature is stable. Try to avoid planting when there is a large temperature difference or when the temperature is low.

The loofah belongs to the climbing type of vegetables, and the growth process should build a melon shed to meet the habit of climbing the loofah, and the melon shed should master the height, generally more than two meters, with strong ventilation and good illumination, and also pay attention to removing the side vines in time to promote the main vine to form melons. In addition, it is also necessary to ensure reasonable watering, generally need to ensure that it is watered every day, unless it rains, because the demand for water for loofah is particularly high, and it is enough to water every day to ensure that the soil is moist, which we need to do in place.

There is no obvious definition of the planting time of loofah, spring, summer, autumn and winter, and the field planting generally chooses summer and autumn open field planting, which can be sown in the way of soaking and direct seeding. The loofah has the habit of liking fertilizer, in order to make the loofah planting to achieve high yield and high harvest, you must choose those plots to the sun, but this kind of loofah also has a disadvantage, that is, there are too many seeds, generally the author only eats the loofah skin, used to soak the sauerkraut to eat. No matter what kind of loofah, if you want to get a high yield, the first and most important thing is to set up a good shelf.

The area of a loofah vine can reach about 10 square meters.

After planting, you can build a trellis for the loofah to facilitate the growth of the loofah vines, you can use a wooden stake with a diameter of about 15 cm, the height of the stake is about 250 cm, insert the 40 cm part of the bottom of the stake into the soil, and place a bamboo pole around the stake to keep the stake upright. Bamboo strips can be placed on top of the trellis in a net, which can promote the elongation of the loofah vines. Water and fertilizer management should keep the soil moist during the growth period of the loofah, so that the loofah can receive rainwater and pay attention to drainage when there is more rain.

After planting the loofah, apply river mud to it, apply rotten manure once before it goes to the shed, and apply phosphorus and potassium fertilizer about once every 8 days after it goes to the shed.

When planting loofahs, first of all, we must pinch the tip, and then we must pay attention to fertilizer and water management, and we must build a frame in time to lead the vines, choose some high-quality varieties, and leave 1 2 melons on the strong side vines and then pluck the top.

First of all, when planting, we must choose the soil is more fertile and wide land, and use farmhouse fertilizer, do not use fertilizer bought outside, water the plants more, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray insecticides in time.

After planting loofah in summer when fertilizer water enters the melon setting period, the requirements for water and fertilizer are higher, generally watering once every 3-4 days, and watering in the morning and evening is better. Effectively combined with watering and topdressing to promote melons, growers can apply well-rotted farmhouse fertilizer to open ditches and apply deeply, and then combine with urea, phosphate fertilizer and potassium sulfate and other ternary compound fertilizers. At present, it has entered the middle of summer, which is the peak period of concentrated flowering and melon setting of loofah, and it is of great significance to strengthen the management of the four areas of the concentrated melon setting period of loofah to improve the yield of loofah and ensure the planting efficiency of loofah.

Generally, 2000 kg of organic fertilizer per mu, 50 kg of nitrogen, phosphorus and potassium (15-15-15) compound fertilizer as base fertilizer, top dressing 1 time 7-10 days after planting and slow seedling, 1-2 times per harvest after melon formation, top dressing 1 time, generally 5 kg of urea per mu, or 10 kg of compound fertilizer. It can be seen that the loofah is not only resistant to high temperature but also high humidity, suitable for warm, sunny, high air humidity and sufficient soil moisture environment. In this environment, the loofah has lush stems and leaves, many fruits, long harvesting times and high yields.

If you want to plant loofah, you must choose good seeds, we must choose high-quality, high-yield, good commerciality, suitable for the market varieties, we feel that the two varieties of green and double green are better. The seeds of the loofah are relatively hard and need to be raised. Because the loofah is a potassium-loving plant, if you use mulch, it is best to manage it carefully when it is a small seedling, because it is relatively brittle, therefore, we must plant it in time.

It can bear fruit in advance, and the appropriate sunshine and temperature during the whole growth period are conducive to the growth and development of stems and leaves, as well as flowering and fruiting. In this way, the purpose of high yield can be achieved, the loofah is a temperature-loving and heat-tolerant plant, and the suitable temperature for the growth of the loofah is 20 to 30 °. Let's talk about some precautions when planting loofahs.

To grow loofahs, it is necessary to build greenhouses, which can be cut into some foundations with some stumps or cement. And when building a greenhouse, the height should not be excessive, because the loofah has a strong climbing ability.

You can use clips, you can manage them with nets, and you can add these to them, so it's the best, and it's good to make it grow very fast.

First of all, in the process of planting, we must choose the soil is more fertile and broad land, and when fertilizing, we must choose farmhouse fertilizer, do not use fertilizer bought outside, we must often water the plants, and also prevent the occurrence of pests and diseases.

The loofah can be cultivated by raising seedlings in advance and planting on the balcony immediately after the final frost. Trellis cultivation is generally used on balconies (such as flat scaffolding, semicircular tunnel scaffolding). Before sowing, seed disinfection, soaking and germination are carried out, and the treatment method and seedbed preparation, sowing, seedling management, etc. can refer to the seedling raising methods of cucumbers.

The soaking time is generally 8 10 hours, and germination can be germinated and sown in 2 to 3 days. Due to the large size of the seeds, the soil should be about centimeters when sowing.

Luffa is a relatively common vegetable in life, and the market demand is also particularly large, the prospect is very good, and the area planted in our country is quite a lot. Not only can it be grown in greenhouses, but it is also very good to cultivate it in the open air. The temperature in summer is very high, and the speed of loofah seedlings is also very fast, if it is cultivated in greenhouses, the management and quality and yield of loofah will be affected to a certain extent.

Valuation managementThe loofah itself is a kind of spreading vegetable, and after planting, it is necessary to build a melon shed, and it must meet the habit of loofah. When building a melon shed, you must control the flower pot, the height can not be too low or too high, it is recommended that it is about two meters, and the shape of the melon shed is mostly semicircular. When the loofah seedlings grow to two meters, they will spread reasonably and climb the shelf, and when the melons are removed, they can also promote the melon vines to find the melons.

Fertilizer and water managementThe seedlings will appear one month after the loofah planting, and the demand for nutrients is also particularly high. In this way, different nutrients are guaranteed at different stages, especially in the early stage of melon bearing, and sufficient nutrition must be provided. The second topdressing will improve the efficiency of melon formation.

Every time you pick melons, you can top dressing once, control the process of watering, not too much, if there is stagnant water, you should also do a good job of eliminating and selecting. <>

Weed managementNo matter what is planted, it is necessary to remove the weeds inside in time to avoid weeds affecting the nutrients needed by the loofah seedlings, and then relax the soil. Even if there are a lot of loofahs, if there is no management in the later growth process, it will affect the sales problem. Pay attention to the strength, do not hurt the roots of the melon when cultivating the soil, which will expose the growth of the roots and seedlings and affect the fruit of the melon.

Especially in the summer, the amount of fruit is very large, and the work force of each picking is also particularly large, in order to reduce the impact of unripe melons and fruits on the quality, we must wait until they are ripe before picking.

Generally, the growth temperature of the loofah is about 20, but the survival temperature of its fruit is about 27 degrees, so that they can shine enough sunlight, so as to ensure that they can flower and bear fruit, and there should be fertilization when watering, generally watering 1 2 times, and when it is ripe, it should be used with sufficient water once, and it should be noted that it should prevent the production of some germs and carry out prevention and control.

The temperature should be controlled above 20, and excess weeds must be pulled out, ventilation management should be strengthened, and more sunlight should be used.

First of all, the temperature in the room should not be too high, and then it should be properly watered and fertilized, and weeds should be removed from the land.

Adjust the temperature and light to have a higher temperature in the whole growth period, the suitable temperature for growth is 20 24, and the suitable temperature for fruit development is 24 28. Around 15 loofahs grow slowly, and below 10 growth is inhibited. In the management, the temperature in the greenhouse should be kept at 25 30 during the day and about 18 at night.

Before the loofah is extracted, the sunshine time can be properly controlled to promote the growth of stems and leaves and the differentiation of female flowers. During the flowering and fruiting period of loofah, it is necessary to open the grass in time and make full use of the sunlight to raise the temperature, so as to facilitate flowering and sitting melon.

Timely watering and topdressing loofah seedlings do not require much water, depending on the moisture situation, watering 1 2 times in a timely manner. When the loofah vine is about 5 cm long, combined with the soil, 30 kg of potassium dihydrogen phosphate per mu is applied, and the water is poured once. The flowering and fruiting period of loofah is in mid-May, the temperature is high, generally watered once every 7 8 days, and 5 kg of urea per mu is applied at the same time.

Set up a frame to tie vines, plant adjustment loofah vines up to 8 meters long, when the vine is about 25 cm long, it needs to be erected. In order to reduce the space occupied by the pole and shade, it is generally tied directly to the greenhouse support with iron wire or nylon rope to form a single-row vertical frame, the top is not crossed, and the vines are vertically led upwards according to the original planting row spacing and density. After the loofah vine is put on the shelf, every 4 5 leaves are tied 1 time, and the S-shaped binding method can be used.

At the same time, pay attention to the timely fall of vines. Since the loofah itself is more resistant to disease, the leaves on the fallen vine do not need to be removed.
