Planting method for white flesh loquats and greenhouse thereof

Abstract

The invention discloses a planting method for white flesh loquats and a greenhouse thereof. The method comprises the following steps: transplanting white flesh loquat seedlings to specified positions at the planting density of (3-5)*(2-4) meters in February to April, preferably March; and fixing poles 25-50 centimeters away from the transplanted white flesh loquat seedlings, keeping four side branches as main branches after side branches sprout each year, keeping three branches sprouting on each main branch for serving as secondary main branches, keeping three branches sprouting on each secondary main branch for serving as a fruiting branch group, and culturing for three and a half years till branches of each tree body reach grade 9-10 so as to enter a blossoming and fruit setting period. Specific to the problems existing in the conventional greenhouse equipment and open field white flesh loquat production, the planting method and the structure of a greenhouse facility are improved, so that yield reducing factors such as freeze injury, fruit cracking, sun burn and the like are eliminated completely, and the aims of preventing freezing in winter as well as shading from rain to prevent fruit cracking and shading from high temperature to prevent sun burn at a fructescence period can be fulfilled.

Description

technical field [0001] The invention relates to the field of processing and manufacturing of agricultural planting equipment, in particular to a planting method of Baisha loquat and a greenhouse thereof. Background technique [0002] Loquats are divided into Hongsha (red meat) varieties and Baisha (white meat varieties) varieties. The Baisha variety is deeply loved by consumers because of its sweet-like honey taste and strong fragrance, and its price is much higher than that of the Hongsha variety. At present, the market price of white sand loquat varieties in my country is 40-80 yuan / kg, while the price of red sand varieties is only 12-20 yuan / kg. Although Baisha loquat has good quality and high price, it blooms earlier than Hongsha variety in autumn, and the young fruit is very easy to freeze and die in winter, resulting in reduced yield or even no harvest. Therefore, freezing injury is one of the important factors restricting the growth of Baisha loquat yield and the ex...

Problems solved by technology

However, there are many weaknesses in the traditional plastic greenhouse facility cultivation, coupled with the lack of targeted management technology, it cannot solve the problems of Baisha loquat freezing damage, fruit cracking, sunburn, etc.

One is that the ventilation of traditional greenhouse facilities is poor. Only the skirt film and side doors can be opened for ventilation and cooling. The top film cannot be uncovered and the skirt film is only opened by 1m. When the sun is strong at noon in winter or at noon in spring and summer, the temperature inside the shed is high. If the temperature is above 10℃ outside the shed, it will often cause a high temperature of 35℃ or more in the shed, which will cause sunburn on the surface of Baisha loquat fruit; secondly, the shed lacks an external sunshade cooling device. Loquats are dehydrated and shrunk. Thirdly, the existing greenhouse facilities management technology lacks pertinence. Technologies such as the determination of the closed skirt time and the temperature and humidity management in the greenhouse do not target the characteristics of loquats, which leads to premature end of dormancy in greenhouses for loquats in winter. When the growth resumes, when encountering strong cold air, the frost resistance of Baisha loquat in the greenhouse is not as good as that of dormant fruits in the open field, which directly causes the phenomenon that the young loquat in the greenhouse is more severely damaged than the loquat in the open field.
