When planting lettuce, how to use farmhouse fertilizer correctly?

In lettuce planting, cooked rot farmhouse manure can be used as a base fertilizer; Growers can decide the amount of farm fertilizer according to the soil fertility of the planting site; Under normal circumstances, it is advisable to apply 2500 kg to 4000 kg of cooked rot and sterilized high-quality farm fertilizer per mu; Lettuce planting is generally transplanted by seedlings, from the beginning of the seedlings to use farm fertilizer, but the use of farm fertilizer must be already rotten, without fermentation and rot farm fertilizer is not much nutrients. The method of fermentation is to collect pigs, cattle and other livestock and poultry manure and bedding, add human manure and urine, and then accumulate and ferment. Lettuce has strict requirements for fertilizer and water, and improper management will cause overgrowth and premature sprouting, and cannot form fat and tender fleshy stems.

Spring lettuce. The sowing date is after September of the first year, and the growth stops for a period before winter. After planting and slowing seedlings, fast-acting nitrogen fertilizer was applied, with kilograms of urea or 10 kg of ammonium sulfate per 667 square meters.

<> first time was after the lettuce survived. At this time, it is necessary to lift seedlings, so at this time nitrogen fertilizer-based fertilizer should be applied, 5-8 kg of urea can be applied per mu, or human feces and urine can be sprinkled, and about 600-800 kg per mu should be used with diluted human feces and urine 2-3 times. When the rosette leaf is formed, the fleshy stem begins to grow and expand, and it is necessary to pay attention to the management, and it is easy to cause the fleshy stem to crack due to drought and waterlogging or top dressing too late.

Therefore, with the gradual increase in temperature and the increase of rain, a slight negligence causes a reduction in production, in case of dry weather, timely irrigation, when the rain is excessive, should be immediately drained to resist waterlogging.

In order to ensure its rapid and strong growth, the spacing and row spacing should be kept 25cm 30cm, watered in time to promote root development, keep the soil moist, if the planting is a high temperature period in summer, it should be properly shaded to avoid damage to the seedlings. After applying plantar fertilizer, there is basically no need to fertilize a piece of black soil fertile land, transplant the seedlings that grow into the ground to transplant to the land, you must choose good weather when transplanting, the day is too hot to dry the lettuce seedlings, the downpour will knock the lettuce seedlings to the ground, and the drizzly weather is the most suitable for transplanting lettuce.

In fact, when using, you can directly mix these farm manure and water in a certain proportion and pour them into the ground, so that they can play a role in fertilization.

The nutrient needs of lettuce during growth will vary with the change of growth stage. In the long period, the amount of lettuce compound fertilizer is very large, so it is necessary to pay attention to the timely application of lettuce compound fertilizer, and then in the post-maturity period, the amount of lettuce compound fertilizer should be appropriately reduced to prevent the decline of storage capacity. The potassium requirement of the posterior lettuce is large, followed by nitrogen, followed by phosphorus.

We must grasp the frequency of fertilization, pay attention to the appropriate dilution of manure, this ear sample can promote the growth of seedlings, to ensure that nitrogen, potassium, phosphorus are complete.

In the process of planting lettuce in the village, the use of farm fertilizer will make the lettuce grow better, which is a natural pollution-free planting before the disadvantages. But water immediately after fertilization.

When using farmhouse fertilizer, it must be rotten, it must not be fermented, and it must be uniform when fertilizing.

Rural planting lettuce, the use of farmhouse fertilizer can ensure the normal development of lettuce roots, and the use of fertilizer due to lettuce and oxygen requirements are very high, so farmhouse fertilizer must ensure the absorption of water and nutrients, because farmhouse fertilizer is also called organic fertilizer, so its cost is not high, but the nutrients contained in it are very rich, in addition, in the aspect of fermentation, you can consider using weeds or various garbage as raw materials for fermentation, you can choose according to your own situation according to local conditions, When the choice is followed, you can turn it into the soil for fermentation, of course, you can also use some commonly used hot fertilizers according to your own situation, such as Yang De is a pig phoenix, which can also be used quickly after fermentation.

Generally, common farmhouse fertilizer is a hot material, you can consider the use of sheep manure or pig manure, cow manure is very rich in nutrients, and there are a lot of organic matter and a variety of lettuce growth nutrients, put in the soil for the first time to sell, and then ferment, at the appropriate time to add some water, so that he maintains a certain degree of heat, at this time the nut is basically fermented in about a month, in this case, the lettuce is fertilized, can ensure a lot of nutrients for lettuce.

Of course, plant ash can also be used, but there will be a large number of nutrients such as calcium, potassium and other nutrients, which can generally be used as base fertilizer, and the plant ash can be mixed with the soil to add lettuce, not to mention that, it can ensure the rapid growth of lettuce. Lettuce has a strong absorption capacity, its root system is relatively developed, so, during the daily topdressing period, we must keep the soil moist to avoid uneven dry and wet conditions, it is very easy to cause liver meridian cracking, and top dressing, do not be too frequent, you can slowly carry out top dressing after survival.

Generally, farmhouse manure is used and eaten three times a day. It's about 500 grams at a time. Drip irrigation is an option, and in addition, no irrigation is allowed in it.

It can be diluted relative to the farmhouse fertilizer, and then evenly sprayed in the soil, but also on the roots of the lettuce, so that the fertilizer can be better used.

It is suitable for the use of fertilizers containing trace elements, so when using fertilizers, we must pay attention to the fertilization of farm fertilizer, and be sure to let it rot. When using farmyard fertilizer, you can also dilute it before using it.

The most feared thing is potassium fertilizer, so don't use potassium fertilizer when planting lettuce, you can choose some nitrogen fertilizer.

The most feared thing is potash, so don't use potash when growing lettuce.

Lettuce is very afraid of chicken manure that is not well rotted, which contains harmful substances that will slow down the growth of lettuce.
