The difficulty of harvesting safflower filaments is a problem for the development of the safflower industry. In this research, a harvester that uses reciprocating shearing to harvest safflower filaments was developed and then tested by harvesting No. 5 Yumin stingless safflower plants in Xinjiang. Whether to install fixed blades, the DC motor speed, and the installation angle were the test factors, and the net harvest rate and impurity content were the response indices. The optimal parameter combination was obtained by a quadratic orthogonal regression test. The optimal parameters were DC motor speed of 150 r/min, installation angle of 45° and fixed blades. In field testing, the harvesting rate of safflower filaments was greater than 95%. The test results were close to the predicted values, and the model was verified as effective.
The present study was conducted in Karnal, Rohtak and Jhajjar districts of Haryana state covering 360 respondents. Results showed that majority of the respondents had availability of refrigerator, sickle, scooter/motorcycle, accessed safe drinking water within the premises, had toilets within their house with flush type of sanitary latrine, had electricity and separate space for cooking and were using LPG for cooking. Overall Livelihood Security was found medium in all the selected three districts. Therefore, in case of significant and positive correlation of independent variables with livelihood security indicators, the null hypothesis (Ho) was rejected in relationship between independent and livelihood security of farmers. Livelihood security had significant and positive relationship with z value at 5 per cent level of significance which showed that it is between -1.96 to +1.96, therefore, the data falls between the acceptance region, that’s why null hypothesis is accepted.
Soilless cultivation is a way to overcome the obstacles of continuous cropping, secondary salinization and other issues. Due to the weak buffering capacity of root microenvironment and high sensitivity for changes in the environment, the control of root zone temperature is difficult. A novel type of soilless culture facility was designed to solve the above problem, which was composed of soilless cultivation trough, cultivation bracket, water and sewer pipelines, and temperature control system. Three experiments were taken to test its control performance,1) By the experiment on temperature control performance test of flow water, it was validated that the designed soilless culture facility could control flow-through water temperature effectively and accurately 2) After finishing the experiment on temperature control performance test of culture substrate in cultivation tank, it could be verified that the novel soilless cultivation facility could control the temperature of culture substrate in cultivation tank accurately and effectively 3) The experiment on lettuce growth under the effect of root zone temperature control was done, which could prove that root zone temperature affects crop’s growth directly. Experimental results showed the practicality and the reasonability of the novel soilless culture facility and its root zone temperature control system.
The present study was conducted in Karnal, Rohtak and Jhajjar districts of Haryana state covering 360 respondents. Results showed that the respondents were from age group 36-50 years who belonged to general caste and educated up to middle school were married. They belonged to joint families and had small sized families having up to 4 members in a family with involvement in farming. The respondents had less than 2.5 acre of land which was fully irrigated and had owned pump/bore/tube well as irrigation source. They had pucca house with an annual income more than Rs. 2 lakhs and had more than 10 years of farming experience. Majority of the respondents had access and high utilization to mobile phone and internet.
Aiming at the current obstacles to the continuous cropping of facility vegetables and the serious damage of root-knot nematode diseases in the greenhouse vegetables. In this paper, a comprehensive equipment for reducing obstacles in continuous cropping of protected vegetable soil was developed. Through the theoretical calculation of soil subsoiling device, the component parameters of subsoiling device were obtained. Through the combination of empirical design and theoretical design, the design of key components of soil subsoiling device was determined, and the prototype trial production was completed. In order to deeply analyze the interaction process between blade and soil, a blade soil finite element model was established. The field test results of the prototype showed that the subsoiling depth of the machine was 390 ~ 410 mm, the average ditch depth was 395 mm, the stability coefficient of ditch depth was 98.3%, the average ditch width was 495 mm, and the consistency of ditch width was 98.5%, which basically meet the agronomic requirements. Through the comparison of soil compactness before and after operation, it could be found that after deep loosening, the soil was obviously loose, the soil hardness decreased, and the soil permeability was improved. The incidence rate of 40 days after transplanting was only 53.5%, which was 23.6% incidence rate compared with the reference area. At the same time, this paper could provide reference for the obstacle reduction of soil continuous cropping in orchards, mulberry orchards and tea orchards.
