Sprinkler Irrigation of Soybean at Grain filling stage
Soybean still needs some water and nutrients to promote material accumulation and maturity, increase seed setting rate and increase yield when soybean enters the grain filling stage and maturity stage. For many years, soybean has entered the grain filling stage, which is generally very dry, which has an adverse effect on the grain filling maturity of top and upper soybean. In response, some farmers used sprinkler irrigation well water to alleviate the drought during this period. The production practice has proved that the soybean pumped and sprayed at the grain filling stage can not promote maturity, but will lead to the early withering and death of some branches and plants, thus reducing the yield. The reason is that soybeans

Control of soybean root maggot
Soybean root maggot is also called Liriomyza sinensis. Only harms soybeans and wild soybeans. The larvae bite on the roots of soybean seedlings, form maggot channels, and excrete feces, resulting in root rot, dwarf of bean plants, and death of seriously damaged bean seedlings. This worm occurs only once a year. The pupa overwintered in the soybean root bark tumor or soil seam, and in the middle and late May of the next year, the pupae emerged into adults, laid eggs at the soybean roots, hatched larvae, and harmed the roots of soybean seedlings. Control methods: seed dressing with chemicals to prevent larvae, 40% dimethoate EC mixed with 0.7% of the seed amount, spray to the water, spray while mixing. Such as mixing

Effective control of soybean root Liriomyza sinensis
Soybean root miner Ophiomyiashibatsuji (kato), also known as Liriomyza huidobrensis, belongs to Diptera, Liriomyidae. Commonly known as soybean root maggots, bean root snake flies, root flies and so on. First, distribution and harm. Soybean root miner is mainly distributed in the main soybean producing areas, and is distributed in three provinces of Northeast China, Inner Mongolia, Hebei, Shandong and Shanxi, among which Heilongjiang, Jilin and Inner Mongolia are the most prominent. Liriomyza sativa is mainly harmed in soybean seedling stage, and its feeding habit is single, only harmful to soybean and wild soybean. Larvae in soybean

Application technology of soybean rhizobium
The use of rhizobium in soybean production is a mature and widely used technology, which can greatly improve the nitrogen fixation ability of soybean during the growing period and supply sufficient nitrogen for soybean production. Soybean rhizobium has two dosage forms: liquid and solid. Solid rhizobium was applied by seed dressing or soil application. Liquid rhizobium was used by soaking seeds. Soybean rhizobium agent can also be added when seed coating, but it should be noted that the coating agent and rhizobium agent should match each other, and the activity of rhizobium should not be inhibited because of the effect of seed coating agent. one

What are the characteristics of each development stage of soybean?
(1) germination period: it takes 10-15 days for spring soybean and 4-6 days for summer soybean when seeds germinate until seedlings are unearthed. The germination period of soybean mainly needs appropriate temperature and suitable soil moisture, and it is required to do a good job of seed treatment before sowing, improve the quality of soil preparation, master timely sowing, ensure loose soil in the field, prevent excessive soil moisture and poor permeability, and delay seed emergence or even seed rot. (2) Seedling stage: refers to the period from unearthed seedlings to flower bud differentiation, which requires daily average temperature of more than 20 ℃ and soil of 19% and 20%.

Key points of high-benefit technical cultivation of soybean
Soybean is one of the most important oil crops in China. Shandong soybean is famous in China. Shandong Province-has a unique advantage of soybean seed breeding, year-round stable production of soybean seed production base. Its improved varieties are exported to most of Shandong, Henan, Jiangsu, Anhui, Shanxi, Hebei and other provinces hundreds of counties and cities, known as hybrid beans, become famous brand products in the Yellow and Huaihe River Basin. The high-yield cultivation technique of soybean is one of the important technical measures to obtain high yield. In order to obtain a higher yield level, it is necessary to implement the matching of improved varieties and methods in order to achieve the goal of high yield and bumper harvest.

New technique of cultivating Pleurotus ostreatus with sweet potato vine
Sweet potato, also known as sweet potato and red potato, contains 8.1% crude protein, 1% crude fat, 28.5% crude fiber, 1.55% calcium, 0.11% phosphorus and trace amounts of lysine, methionine, isoleucine and so on. Sweet potato vine can be used to cultivate Pleurotus ostreatus by adding appropriate auxiliary materials, which is a good raw material for high quality and high yield. The specific practices are as follows. 1. Raw material handling. After harvesting and digging sweet potatoes, move the vines to the ground to make them 2-3 cm long, dry them in the sun, and pack them in woven bags. two。 Culture material formula. Use 10

Cultivation of Pleurotus ostreatus with bean straw bag wall
Using bean straw as culture material, Pleurotus ostreatus is cultivated by the combination of bag cultivation and wall cultivation, which can reduce the cost and improve the benefit. Preparation of culture materials: dry and mildew-free bean stalks were crushed after 2-3 days of sun exposure. Culture material formula (by weight): soybean straw powder 78%, wheat straw 10%, soybean cake 5%, corn meal 2%, gypsum 1%, calcium superphosphate 3.5%, urea 0.5%. The culture material was mixed with 130 kg of water and then piled up and fermented for 3 times during fermentation. Bagged inoculation: fermented culture

Winter cultivation of oyster mushroom three attention
1. Mushroom field selection: The ideal place for winter cultivation is the mushroom field with warming and heat preservation conditions, such as indoor mushroom house with warming conditions, underground mushroom field with higher temperature and Yangqi mushroom field cultivated in plastic greenhouse. The temperature of this kind of mushroom field can be controlled above normal temperature, so it is beneficial to the growth of fungi, and it can also be early fruiting. Usually, outdoor mushroom field can be selected for early winter planting time, and indoor mushroom house should be selected for late winter planting time. 2. Selection of strains: According to the arrangement of mushroom production period, winter planting Pleurotus ostreatus can be divided into winter planting and spring planting. The former selected low temperature varieties or medium and low temperature varieties

Heat preservation method of Pleurotus ostreatus cultivated in winter
The success rate of cultivating Pleurotus ostreatus in winter is high, and it is also a good time for people to make use of their spare time to get rich. However, when the temperature is low in winter, the bacteria of cultivated Pleurotus ostreatus are slow or delayed, and abnormal mushrooms are produced during the period of mushroom production. Heating with coal stove will not only increase the cost, but also cause poisoning of mushroom body. In practice, I created the method of using biological energy to keep Pleurotus ostreatus in winter, which has the advantages of cost saving and hygiene. This technology is introduced as follows: 1. Pleurotus ostreatus should be cultivated with bag material in late autumn. When the temperature is cold, there is half a bag of hyphae.
