What are the requirements for water and fertilizer when planting pumpkin to increase yield?

When pre-seedling, add diammonium phosphate to rotted sheep manure, add 5 kg of diammonium to one acre of pre-seedling soil, and the ratio of soil and sheep manure is 8:2When the pumpkin is planted, water enough, at the same time, apply compound fertilizer or di'an phosphate 5 kg plus 4,000 kg of urea potassium sulfate 100 grams per mu, and water enough water to apply urea 5 kg per mu when flowering and fruit setting, or biological fertilizer, the pumpkin will have less water demand in the later stage, and there will be no need to water it when the weather is not very dry.

Pumpkin planting must be done with farmyard fertilizer and watering once a week, which can improve the melon setting rate and yield, and during pumpkin planting, it is sometimes necessary to pollinate by hand.

To plant pumpkin to increase yield, the requirements for water and fertilizer must first have sufficient water sources, and secondly, clean water sources. Due to the modern mechanization and serious air pollution, it is very difficult to require the purity of water sources.

To plant pumpkins, you must use farmhouse fertilizer, plant ash, choose some phosphate fertilizer or nitrogen fertilizer, loosen the soil in time, often replenish the soil with nutrient solution, water regularly, and keep the light sufficient. It can increase the melon setting rate and yield of pumpkins.

If you want to grow pumpkin for high yield, it is best to choose farmhouse fertilizer with appropriate calcium substance. Farm manure can choose chicken manure or pig manure. It is suitable for fully decomposed farmhouse fertilizer, not suitable for raw fertilizer

When we grow pumpkins, we should not use chlorine fertilizer, because it will affect the starch glycos, so that the sugar content is reduced, and we should not use cow dung. In short, pumpkin is most suitable for organic fertilizer with nitrogen, phosphorus and potassium compound fertilizer.

It is better to choose well-rotted farmhouse manure. It is best not to use fertilizers that contain chlorine. Scientific fertilization is needed in order to achieve high yields.

<> some farmers grow pumpkins, they always find that their pumpkins can't bear a few melons on a vine, and the neighbor's pumpkin is big and sweet, and they don't understand why their pumpkin vine is not worse than that of their neighbors, and why there is this phenomenon in terms of yield? In fact, in the different growth periods of pumpkin, the demand for fertilizer is different, the management measures are not the same, only in the different growth periods of pumpkin for reasonable fertilization can improve fruit expansion and coloring and promote the differentiation of female flowers, through pruning and topping to inhibit vegetative growth, improve the rate of pumpkin, and the prevention and control of pumpkin pests and diseases is also an indispensable measure in the planting of pumpkin, only do a good job of these management measures to double the pumpkin yield.

Pumpkin has a well-developed root system and strong fertilizer absorption ability, so it is necessary to apply sufficient basal fertilizer before planting, mainly with well-rotted organic fertilizer, and mixed with nitrogen, phosphorus and potassium compound fertilizer to help pumpkin thrive; There are two methods of sprinkling and concentrated application of base fertilizer, when sprinkling is generally combined with deep ploughing, after evenly spreading organic fertilizer or compound fertilizer, use a screw plow to reverse the suspicion of re-rake twice, so that the fertilizer and the soil are evenly mixed. When the fertilizer is less, the ditching is generally used to concentrate on the strip application, and the fertilizer can be applied in the sowing row.

The first is to apply sufficient basal fertilizer. Pumpkin needs a lot of water and fertilizer to grow, and it is necessary to apply sufficient basal fertilizer when planting to ensure sufficient fertilizer and water supply during the growing season.

The second is to hit the top at the right time. When the pumpkin vine grows to 2 meters, remove the growth point on the main vine, so that the main vine grows 3-4 branches, and flowers and fruits.

The third is to build a scaffold. When the branch grows to 2 meters, the vine is put on the shelf, which can improve the light transmission and ventilation conditions, so that the melon sitting rate can be increased by more than 40%.

Honey pumpkin is a hybrid generation of pumpkin varieties, also known as dog meat pumpkin, vine, branching is strong, the main side vines can bear fruit, honey pumpkin is sweet, powdery, delicate taste, rich in protein, vitamins, minerals and a variety of trace elements, is one of the varieties with better quality in Chinese pumpkin cultivation, suitable for cooking and deep processing.

When we fertilize pumpkins, we should do it according to the characteristics of pumpkins. Pumpkins have different nutrient needs at different growth stages. For example, when the pumpkin is young or in the seedling stage, the growth amount of pumpkin is not large, so the need for fertilizer is not high.

When the fruit is enlarged, the absorption of nitrogen and potassium by pumpkin will increase greatly. During the whole growth period of pumpkin, the nutrient requirement is nitrogen and potassium is the highest, followed by calcium, and the absorption of magnesium and phosphorus is the least.

1. The seedling stage and vine extension stage of pumpkin are mainly based on fast-acting nitrogen fertilizer under the condition of applying sufficient rotted organic fertilizer, which is determined according to the fertility and barrenness of the land. 2. Water and fertilizer management of pumpkin sitting melon period and pumpkin fruiting period: after pumpkin sitting, in order to reduce physiological phenomena such as falling melon, timely topdressing and watering are the key, apply 15 kg of urea and potassium sulfate per mu about 8 kg, divide and dismantle 2 times, pay attention to cultivating loose soil once after fertilization and watering, and fertilize and resell the pumpkin normally in the melon-bearing period.

3. In the later stage of pumpkin fruiting, due to the photosynthesis of leaves and the ability of roots to absorb nutrients are also weakened, fertilizer and water management in this period is mainly to prolong the function of leaves, and can not be watered more, you can consider using leaf fertilization to supplement the nutrients needed by pumpkin, and the foliar fertilizer is sprayed once every 10 days for 2-3 times.

The roots of pumpkin are well developed, and the absorption capacity and drought tolerance are relatively strong. However, the leaves of pumpkin are also relatively large and very numerous, so the evaporation effect is also very vigorous. Therefore, we must do a good job of irrigation and watering to ensure the yield of pumpkins.

After the pumpkin is officially eaten, it is generally watered again after about 7 days to promote the growth of branches and leaves. And, after sitting the fruit on top of the pumpkin, sprinkle the puffed fruit once. After that, it is necessary to do a good job of watering according to climate change, soil conditions, etc., to promote the growth of pumpkins.

When the fruit grows, the water should be appropriately reduced to improve the construction quality accumulation and quality of the pumpkin fruit. The top dressing of pumpkin is mainly nitrogen fertilizer, and at the same time, it should be matched with an appropriate amount of phosphorus and potassium fertilizer. When topdressing, it is necessary to divide and top dressing according to the different growth times of pumpkins and the needs of nitrogen, phosphorus and potassium fertilizers.

At the seedling stage, nitrogen fertilizer should be topdressed, and about 6 7 catties should be added. During the fruiting period, we should not only inject enough nitrogen fertilizer, but also replenish phosphorus and potassium fertilizer in time to make the fruit swell normally. After sitting on the fruit, top dressing should be done about twice or so.

When topdressing, we should pay attention to the position, not directly hit the plant, to avoid, and not to bring fertilizer damage to the plant. The basic fertilizer of pumpkin is generally based on organic fertilizer, which is paired with an appropriate amount of compound fertilizer. Among them, the common compost and green manure are used in large amounts, generally accounting for the general extent of all fertilizers.

The amount of temple sugar is kept at about 3500 kg, and then an appropriate amount of phosphorus and potassium fertilizer should be mixed, mixed with organic fertilizer thoroughly, and put into the soil. There are generally two methods of fertilization of basic fertilizers: insecticide and concentrated application.

Strabismus should be combined with deep ploughing. If the fertilizer is less, it should be applied intensively in the ditch.

Pumpkin is a vine crop with well-developed roots, deep soil, strong absorption and fertility, so it is highly resistant to drought and barren. Therefore, the soil requirements are not strict during the planting period, but it is best to plant sandy soil with deep soil, good drainage and fast temperature. Pumpkins have less need for fertility at the seedling stage, but the demand for fertility rises sharply after the fruit swells.

In particular, nitrogen fertilizer, potassium and then phosphorus uptake increases, watering. But in the early stages of growth, if there is too much nitrogen fertilizer, the stems and leaves will become longer, and the cucumber will fall off easily. After alleviating the seedlings, water the dry soil and weather changes, generally more on sunny days, no watering or less on cloudy days, more subsidies for sand, and less for clay to prevent soil plate condensation.

If the plant has already borne fruit, in order to promote the expansion of the fruit and refreshment, if it does not rain, it should be watered in time.

In the seedling stage of pumpkin, mainly top dressing nitrogen fertilizer, can promote the development of roots and seedlings, when the pumpkin bears fruit, it is necessary to have sufficient nitrogen fertilizer and timely supplement phosphorus and potassium fertilizer, so that the pumpkin fruit can be fully expanded, before and after pumpkin flowering, fruit expansion period, and then spray some foliar fertilizer to promote the expansion and development of pumpkin, improve yield and quality. When the pumpkin begins to be harvested, you can apply some organic fertilizer in an appropriate amount, mainly to prevent the premature aging of the pumpkin plant, and increase the yield in the later stage.

If you want to make pumpkins have a high yield and a good harvest, you should usually enter, let's do feng shui management I don't know what to do, so manage it at any time, and want to make pumpkins have a high yield and a good harvest.

Fertilizer and water management of pumpkin in China should be carried out according to different growth stages, soil fertility and plant growth. In the application of fertilizer, organic fertilizer and inorganic fertilizer should be coordinated, and organic fertilizer should be increased as much as possible. Generally, organic fertilizer and phosphate fertilizer are used as base fertilizer; Potash fertilizer is also mainly used as base fertilizer, 1 3 as top dressing; Nitrogen fertilizer 1 3 can be used as base fertilizer, 2 3 can be used as top dressing.

According to research, adding phosphorus fertilizer on the basis of a certain amount of nitrogen and potassium can increase pumpkin yield. After the pumpkin seedlings are slowed down, if the seedlings are weak, the leaf color is light and yellow, it can be combined with watering for top dressing, top dressing can be used with 1: (3 4) light manure water, that is, 1 part of human manure and urine plus 3 4 parts of water, the amount per mu is 250 300 kg, and the top dressing is applied to the tree fertilizer.

If the fertility is sufficient and the soil is dry, it can also be watered only without top dressing.

From the perspective of the nutritional requirements of pumpkin throughout the growing season, the demand for nitrogen and potassium is the largest, followed by phosphorus, calcium, magnesium, boron and other elements. The law of fertilizer demand is "less at both ends and more in the middle". The demand for fertilizer in the early and late growth stages is relatively high, and the demand for nutrients gradually increases after seedling slowing, and the demand for nutrients is the largest in the fruiting stage and expansion stage.

Therefore, on the basis of applying sufficient basal fertilizer before planting, pumpkin should be topdressed in time during the growing period. The purpose of pumpkin seedling fertilization is to raise seedlings, strengthen seedlings and plant trees, and topdressing should be based on fast-acting nitrogen fertilizer. Pumpkin seedlings grow in small quantities and generally do not require overwatering and fertilization.

If the seedlings are weak after transplanting and planting, they can be drenched with 10% diluted manure or 6 kg of nitrogen fertilizer per mu with water within 7 days after the seedlings are slowly planted. For plots with good soil moisture, high soil fertility and vigorous growth, less or no topdressing can be applied to prevent pumpkin seedlings from growing.

As pumpkins enter the middle and late stages, the leaves gradually age, the roots gradually weaken, and the ability to absorb water and fertilizer from the soil and produce organic nutrients through photosynthesis gradually decreases. In order to prevent premature senescence and fertilization, prolong the life of leaves, supplement the required phosphorus, potassium, boron, magnesium, calcium and other medium and trace element nutrients, meet the needs of pumpkin flowering and fruiting, so as to improve the yield and quality of pumpkin, fertilization should be applied to the soil together with foliar fertilizer spraying. In the application of foliar fertilizer, it is recommended to spray urea water, potassium dihydrogen phosphate, borax solution, amino acid calcium, brassinolide and other foliar fertilizers 2-3 times at the beginning of the flowering and fruiting stage, and spray once every 7-10 days, which can not only supplement nutrition for pumpkin, but also protect the flowers.

Generally, no fertilization is required during the seedling retardation period, and fertilization can be applied after the end of the seedling retardation. Pumpkin vines need to be topdressed after stretching, mainly to apply rotten farmhouse fertilizer, pay attention to control the amount of nitrogen fertilizer, so as not to promote the growth of vines and affect the later fruit set. Therefore, pumpkin should be sprayed with foliar fertilizer every 10 days, while organic water-soluble fertilizer can make pumpkin vines grow more vigorously.

Spray urea 1-2 times to promote seedling growth. Pumpkin enters the vine extension stage, combined with cultivation and weeding, and 10 15kg of ternary compound fertilizer is applied per mu, which is conducive to the formation of female flowers and the setting of melon. Entering the fruit expansion period, fertilizer and water management should be strengthened to promote fruit expansion, and the ternary compound preparation containing fertilizer and potassium chloride 5 10 kg per mu should be applied.

After that, fertilize once for each melon harvested, and fertilize 3 or 4 times in a row.

Because the pumpkin fruit is large in size and heavy in weight, the bracket chosen should be strong, able to bear weight, and able to support the pumpkin to remain stable. The erection method is generally a "human-shaped" frame or a flat scaffold. When tying tendrils to a shelf, one main side is usually used, leaving only the first strong side tendril, removing the tendrils and diseased leaves on the other side.

Put the main vine on the shelf first, and when the side vine grows to 30cm, cut off the shelf and tie it up.

In addition to the application of basal fertilizer, pumpkin should have at least three times of top dressing during the growth process, the first time is to burn before and after the vine extension period, increase organic fertilizer, balance water solubility; The second topdressing was at the pumpkin swelling stage, and high-potassium water-soluble fertilizer was topdressed. The third top dressing is based on the pumpkin growth, in.

2. The application of organic fertilizer and high potassium fertilizer at the fruit expansion stage of the three fruits is auspicious and deficient. It should be noted that pumpkin needs a large amount of water in the fruit expansion stage, so it needs timely irrigation, and at the same time, it can be used with microbial inoculants to promote root development and ensure the fruit setting rate in the later stage.

How to manage water and fertilizer for pumpkin planting? I can't talk about it because I'm not an expert on it. Go find it. The answer to so many side arguments is much more reliable than what I said about the withered ears.
