Description

Big-arch shelter is planted to kiwi fruit

Technical Field

The invention relates to a kiwi fruit planting greenhouse, and belongs to the technical field of planting greenhouses.

Background

Kiwi fruit (academic name: Actinidia chinensis Planch), also known as exotic fruit. The fruit shape is generally oval, the early appearance is yellow brown, the mature fruit is red brown, the skin is covered with dense villi, the pulp can be eaten, and the inside of the pulp is bright green pulp and a row of black or red seeds. Because the kiwi fruit likes food, the kiwi fruit is named after the kiwi fruit is also named after the kiwi fruit is seemingly called as the kiwi fruit because the peel is coated with hair, and the kiwi fruit is a fruit with fresh and tender quality, rich nutrition and delicious flavor.

The kiwi fruit is soft in texture and sour and sweet in taste. The taste is described as a mixture of three of strawberry, banana, pineapple. The kiwi fruit contains organic substances such as actinidine, proteolytic enzyme, tannin pectin and saccharides, trace elements such as calcium, potassium, selenium, zinc and germanium, 17 amino acids required by human body, and also contains abundant vitamin C, glucose, fructose, citric acid, malic acid and fat.

The kiwi fruit trees are water-requiring and waterlogging-feared, belong to fruit trees with weak physiological drought tolerance and weak moisture resistance, and have strict requirements on soil moisture and air humidity, so that the kiwi fruit trees are most suitable for being cultivated in regions with abundant rainfall, uniform distribution, higher air humidity and moist but no waterlogging.

The drought resistance of the kiwi fruit tree is poorer than that of a common fruit tree, the kiwi fruit tree has large and dense leaf type and large transpiration amount, the water demand is large, and according to measurement and calculation, the transpiration water loss of an adult kiwi fruit tree with the crown area of 25 square meters is more than 75 liters per day. When the water content of soil is reduced to 5% -6%, the water content is insufficient, the growth of kiwi fruit branches and tips is hindered, leaves begin to be drought, the droop of the leaves is reduced, and the leaf edges are withered. During drought, the leaves begin to dry up, irrigation or water spraying is needed in time, and particularly in the seedling stage, the root system is not completely unfolded and needs to be supplemented with sufficient water.

Besides drought resistance, the kiwi fruit trees are afraid of waterlogging, and when the drainage is poor or the waterlogging lasts for 2-3 days, the plants die by about 40%. In plum rain in south China or rain in north China, if the rain is continuously rained and the water drainage is poor, the roots are in a water-flooded state, the respiration of the roots is influenced, the root tissues are rotten for a long time, and the plants die. Therefore, deep furrow (such as a compartment furrow described below) and high furrow cultivation are required during planting.

Kiwifruit canker is a bacterial disease, almost all main production areas around the world occur, and the Kiwifruit canker mainly damages the trunk, branches, tendrils, leaves and buds of Kiwifruit, so that the trunk canker, the branches and tips of the Kiwifruit canker are decayed, the buds fall off, the leaves are scorched, and finally the whole plant dies until the garden is damaged. Is regarded as the incurable disease of the kiwi fruit and the bottleneck problem of the industrial development. The kiwifruit canker pathogen is mainly spread through rainwater, and particularly, the branches and leaves of the injured kiwifruit tree are easily affected.

In a kiwi fruit orchard, in order to keep out rain and prevent kiwi fruit canker, a planting greenhouse is usually adopted for planting kiwi fruits, and a drainage system is also very critical. The general structure of big-arch shelter is planted to kiwi fruit is: the greenhouse comprises a greenhouse main body, wherein the greenhouse main body comprises framework units which are arranged in rows and columns in a transverse and longitudinal mode, and each framework unit comprises an arch bar and 3 upright posts which are used for connecting two ends and the top of the supporting arch bar; the arch bar of each row of framework units is covered with a top film; the lower end of the upright post of the greenhouse main body is fixedly buried in the ground, a chamber ditch for draining water is longitudinally arranged on the ground below the adjacent position between every two rows of greenhouse main body units, two ends of the chamber ditch are communicated into a drainage ditch on the ground, the chamber ditch and the drainage ditch form a drainage system, rainwater flowing down from the top film can be drained to the drainage ditch through the chamber ditch, the rainwater is drained away by the drainage ditch, and the chamber ditch realizes the drainage function.
