Time and technical measures for mustard cultivation
Mustard is a flavour, especially in the middle of the country, where summer is a necessity for every household. Mustard cultivation takes place in spring and summer, spring and summer harvests and summer and autumn harvests. This paper presents only some of the technical points related to the summer mustard cultivation。
First of all, the mustard growth characteristics make it possible to provide good conditions for growth according to their growth characteristics. Mustard mustards are highly resilient, sexually happy, growing in warm and wet environments, less demanding soil, and generally grown, but grow better on loose and fertile soil, with high temperatures and rainy seasons fearing water accumulation and short-term water accumulation leading to death. Seeds tend to develop easily, sprouts are less stringent than temperature requirements, seeds are fertilized at 15-20°c and grow at 20-25°c, and seedlings are resistant to temperatures around 0°c. Mustards are hot and colder, but they can be frozen at below 2°c, and they are not allowed to happen. The seeding period requires soil to be humid, fearing drought and water scarcity. A dry environment in the form of seedlings is characterized by poor rainfall。
Based on the above growth characteristics, the following measures should be taken:
I. Employment to get out of the hell
Mustard is considered to be the most suitable at 20-25 degrees in the light of temperature requirements, so it should be grown by the end of june and by 10 july in the summer. In the future, the seedlings are not easy to grow, and they are weak. Measures to reduce temperature need to be used。
Selection of suitable varieties
The mustard varieties divide the leaves into round leaves and sharp leaves. Round-leaf varieties are thick, short-term, fat-leafed, of good quality, hot and cold and flowery, and are suitable for harvest. Fly leaves are thin, long and thin, but smelly, flowering and growing seeds, and harvesting leaves is shorter. So in the summer of june and july, we should choose the heat-resistant round leaves。
Iii. Fertilizing the whole area
The mustard roots are shallow into the soil, usually at about 15 cm, and grow well on loose land. In addition, leafy vegetables are fertile soil, which requires more nitrogen fattening because of their predominance. It is therefore necessary to establish a good soil environment for mustard growth by tilling and fertilizing, defusing and fertilizing fields before planting. The mustard plantations require scavenging, shattering the soil, which does not affect seedlings, and the small mustard seeds are less powerful. Acres are subject to three to four fertilisations per acre, 80 pounds of compound fattening, so that the fertilizer is spread evenly on the surface of the earth, at a depth of 30 centimetres, and when it is cultivated, it is protected in a timely manner。
Iv. Sowning
Mustard mustard is sowed mainly with dry seeds and does not require seed seeding. Because of the small size of the seed, the water will be soaked with the soil, then the seed will be soaked in the ground from 1 to 2 centimetres, so that the dry earth will affect the seedlings, which will be followed by the cover of the straws in time to cover the shades of the sun, so as to generate the seedlings. When 60 to 70 per cent of seeds are sprouts, the cover is removed in time to prevent the creation of high seedlings. And the top uses sunnets to cover the sun for three to five days against high temperature burns。
V. Post-plant management
As a result of the heat and high evaporation, seedlings should be wetted early or late every day, so that the soil is wet and warm. The tri-leaf period begins with the uprooting of weeds and bush seedlings, allowing for sufficient individual growth space for the seedlings, usually at a distance of 4 cm. The urea was washed with water once, 10 pounds per acre and 15 centimetres or more, followed by fattening once, and could be harvested by 20 centimetres. During this period, water is wet and dry, and the soil is always wet to grow fresh leaves。
