Three ways to increase soybean production
After emergence of inter-seedling soybean, it is an effective measure to increase yield on the basis of whole seedling and early seedling. The effect of increasing yield mainly depends on the time of interseedling, which should be carried out urgently when two opposite single leaves are unfolded. When the first compound leaf of soybean seedlings is unfolded, choose a sunny day at noon and use animal power or machine to bring wood along the ridge to suppress. When pressing seedlings, we should pay attention to avoid cloudy or sunny mornings, so as not to break the seedlings. Pick the heart at the first or full flowering stage of soybean, remove the top of the main stem by hand, about 2 cm.

Secret recipe for increasing soybean production
In order to increase the yield of soybean, in addition to selecting excellent varieties, improving the nitrogen-fixing ability of nitrogen-fixing bacteria and controlling diseases and insect pests, the following four measures can be taken: 1. The specific method is: after the formation of two cotyledons of soybean, all the undeveloped leaves in the upper part are removed. In this way, the double main branch of & ldquo; & rdquo; can be produced. After the formation of the two true leaves, all the upper undeveloped compound leaves are removed to concentrate nutrients on the new main branches, accelerate the individual cell division of the plant, and promote the sturdy stems, luxuriant branches and leaves and pods of soybean.

Technical points of increasing yield of soybean
1. The ecological types of soybean varieties should be properly selected according to the natural conditions of the local soybean producing areas. The podding habits of soybean can be divided into three types: infinite, limited and sub-finite. Zhumadian, where Lao Zhao is located, belongs to the spring and summer soybean area of the Yangtze River valley. Summer cropping is 120 years and 150 days. Varieties with limited podding ability should be planted in this area, or infinite podding varieties may be selected, so the above phenomenon will occur. Therefore, attention should be paid to the selection of varieties, especially in high soil fertility and rain.

Nanometer magnetic fluid for increasing yield and accelerating ripening of soybean
Due to the large temperature change this spring, the closed weeding effect before soybean seedling is poor, the field is small, the phytotoxicity occurs in a large area, the soybean growth is hindered, the root system is poorly developed, the field is seriously stiff, and the growth process is delayed by 7 - 10 days on average. 1, the main performance 1, the new leaf growth is slow, the bottom leaf is yellow, the root rust root is red, and the root rot occurs in a large area at this stage;2, the normal growth field in the field only accounts for about 20% of the total area;3, the single branch is less, less than 20 - 30% or more.

Eight measures to increase soybean production
One is to apply fertilizer to flowers and pods. The growth and development of soybean is the most exuberant in the flowering and podding stage, and it is the period in which soybean needs the most fertilizer in its life. The application of flower and pod fertilizer can reduce the shedding of flowers and pods, promote the fullness of grains and improve the quality. Flower and pod fertilizer should be applied at the early flowering stage, with the combination of nitrogen and phosphorus fertilizer, urea 3kg / mu, phosphate fertilizer 7.5kg / mu, hole application at 5 cm on the side of soybean root, and soil cover fertilizer after application. The second is to spray foliar fertilizer. In addition to the three major elements of nitrogen, phosphorus and potassium, boron, zinc and molybdenum are indispensable trace elements in soybean. Therefore, during the period from flowering to grain filling,

10 measures to increase soybean production
1. Interseedling: on the basis of the whole seedling, soybean seedlings are carried out when two opposite leaves are unfolded, and the yield is generally increased by 10-20%. 2. Pressing seedlings: when the first compound leaf of some soybean seedlings is unfolded, choose a sunny day at noon and use animal power or machine to induce wood to press along the ridge, which can increase the yield by 8.5-10%. 3. Heart picking: in the early flowering or full flowering stage of soybean, about 2 cm of the top of the main stem is removed by hand, which can increase the yield by 7.2% and 10.8%. 4. application of rare earth: 2 kg of rare earth for every 1 kg of soybean seed, or concentrated at seedling stage and early flowering stage of soybean

How to spray nano magnetic energy liquid on soybean
This year, driven by the market, the enthusiasm of farmers in our province to plant soybeans is extremely high, and they have adopted high-yield practical cultivation techniques to increase investment, realizing uniform seedlings, complete seedlings and strong seedlings, laying a solid foundation for large-scale harvest. Recently, a lot of farmer friend calls advisory farming king nanometer magnetic fluid how to spray? The following is a brief introduction: First, foliar spray: What is the role of Nongwang Nano Magnetic Fluid? Nanometer magnetic fluid belongs to non-chemical products, which is magnetic fluid prepared by magnetic medicine biological engineering method.

High-yield cultivation techniques of uniform planting of soybean
The main results are as follows: 1. the planting density, row spacing and plant spacing are determined according to the plant type and branching characteristics of the variety. The main stem type varieties of ① with dwarf, precocious and anti-nephew branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling density 1.8-25000 plants. 2. the planting density is determined by the level of soil fertility and management level. After the planting row spacing is determined according to the variety, the density should be adjusted according to the soil fertility and the level of water and fertilizer management. 3. Sow as early as you can. Early sowing can significantly increase yield and fat content.

New cut flower carnation varieties' Linlong 2' and 'Linlong 3'
Shanghai Forest and Flower breeding Center has cultivated a series of new varieties of carnation (cut flowers, potted plants). Among them, the female parent of 'Linlong 2' cut flower carnation is' marble 'and the male parent is' Hongkashi'; the female parent of 'Linlong 3' is' Lightning 'and the male parent is' Tucks'. In 1998, an excellent single plant was selected and bred by tissue culture and propagation. The two varieties grew neatly and steadily and were authorized by the Ministry of Agriculture for new plant varieties on November 1, 2003. the variety rights are CNA, respectively.

How to cultivate carnation?
Carnation is also known as musk carnation, also known as carnation. Originally from southern Europe. It is a perennial plant and flower. Its leaves are opposite and linetype. The branches are longer. Spend at the top of the branch. The flowers are single and fragrant; they are red, white, yellow-purple and gold-sprinkled, etc. Propagation of Phyllostachys pubescens can be done by cutting, ramet, striping and sowing. General line cutting, but although this method can retain the characteristics of the variety, the amount of reproduction is small, and because of the shallow roots, there is often lodging phenomenon. Therefore, for the purpose of mass production of cut flowers, it is better to sow seeds. The sowing time should be Greater Cold Zhili.
