1. The amount of fertilizer absorbed during the whole growth period of pepper and the proportion of fertilizer required at each growth stage
　　 1. The amount of fertilizer absorbed during the whole growth period of pepper
　　 Pepper is a type of vegetable with a large amount of fertilizer. For each 1000 kg of fresh pepper, about 5.19 kg of nitrogen, 1.07 kg of phosphorus pentoxide and 6.46 kg of potassium oxide are required. If the plan is to use 6,000 kilograms of fresh pepper per acre , taking into account the seasonal utilization rate on the dry land of nitrogen fertilizer (the utilization factor is generally 1.3-1. 5), then the pure nitrogen per acre is 20. 4-23 kg, five. phosphorus oxide 3.2 kg, 20 kg of potassium oxide.
　　 2. The proportion of fertilizer required for each stage of growth of pepper.
　　 The amount of nutrients such as nitrogen, phosphorus and potassium absorbed by pepper in different growth stages is also different.
　　 First, from emergence to bud, because the plants are few leaves small, the dry matter accumulation is slow, so the nutrients needed are less, accounting for 5% of the total absorption; the second is the growth from the bud to the initial flowering, nutrition body rapidly expanding, gradually increasing the amount of dry matter accumulation, increased absorption of nutrients, accounting for about 11% of the total absorption; the third is from the beginning to spend full bloom is the result of a strong period of chili vegetative and reproductive growth, but also the absorption of nutrients and most of the nitrogen element period, absorbing about 34% of the total; Fourth anthesis to maturity, nutrient plant growth is weak, then the requirement for a maximum phosphorus, potassium, about 50% of the absorbent; after closing off the mature fruit, in order to promote growth and foliage during this time and the need for a larger number of nitrogen fertilizer.
　　 Second, pepper root characteristics and protection measures
　　 1. Characteristics of the roots of pepper.
　　 First, the root distribution of pepper is shallow. The transplanted peppers are cut off from the main roots, and the depth is generally 25-30 cm. The roots are mainly distributed in the 5-20 cm soil layer.
　　 Second, the root system of pepper is weakly developed, the amount of root is small, and the adventitious root is not easy to occur at the base of the stem.
　　 Third, the roots of peppers are not drought-tolerant, and they are afraid of cockroaches.
　　 2. Protection measures for pepper roots.
　　 When cultivating, it is advisable to choose fertile soil with good aeration. It is best to use root-protecting seedlings (such as paper tube, plastic raising seedlings, etc.) The seedling age of the planting should not be too large. The seedlings should be used before planting to promote the white seedlings. The occurrence of new roots and soil planting. Paying attention to protecting roots during seedling and transplanting is one of the important links in early ripening and high yield cultivation of pepper.
　 Third, the requirements of pepper on the soil.
　　 Capsicum has higher requirements on soil conditions, and the clay soil retains water and fertilizer retention ability, but the drainage and permeability are poor. After the pepper is planted, the ground temperature rises slowly, the seedlings are delayed, but there is stamina; the sandy soil has good drainage and permeability , after planting The ground temperature is increased fast, and the hair is early, but the ability to protect the hair is poor, and the early stage is easy to prematurely decay; the sandy loam has better fertilizer, water retention and permeability, and is most suitable for pepper growth. The pH of the soil is preferably pH 6. 2-7.

The supporting tube stand is also called the branch pipe seat, saddle seat and saddle type pipe joint. It is mainly used for reinforcing pipe fittings of branch pipe connection, instead of using different diameter three - way, reinforcing plate and strengthening pipe section. It has the advantages of safety, reliability, lower cost, simple construction, improvement of medium channel, series standardization, convenient design and so on, especially in high pressure, high temperature, large diameter and thick wall pipe. It is widely used instead of the traditional branch connection method.
The main body is made of high quality forgings, and the material is the same as that of pipeline materials, such as carbon steel, alloy steel, stainless steel and so on. Both the pipe and the head are welded, and the joint of the branch pipe and other pipes, such as the short pipe, the plug and so on, the connection of the instrument and valve, has many types of welding, socket welding, thread and so on.
